A fire rating is two numbers and a name: how hot the inside may get, for how long, and who checked. Here’s what UL 72, the Japanese JIS test, EN 1047-1, EN 15659 and NT Fire 017 actually test, and what “1 hour” means when it’s your house on fire.
350°F
(177°C): the most the inside of a UL Class 350 safe may reach
420°F
(216°C): the charring point of paper, per the US National Park Service
30 ft
(9.1 m): the hot drop in UL’s and Japan’s impact tests, about three storeys
<5 min
for modern furnished rooms to reach flashover in UL’s 2012 experiments
Key takeaways
- Every fire rating pairs an inside temperature limit with a time in a standard furnace fire. UL Class 350 (paper), EN 1047-1 “P”, EN 15659 and NT Fire 017 “Paper” are all paper classes; data and film need the stricter classes.
- UL 72 and the Japanese JIS test count the cooling period after the fire and offer a hot 30-foot drop test. Not every standard does both, so the same “1 hour” can mean different things.
- A rating is only as good as whoever certified it. UL, ECB•S and SBSC test samples and list the products; “tested to”, “ETL Verified” and in-house claims each mean something narrower, and you have to read which claim each mark covers.
- In 1939 tests by the US National Bureau of Standards, furnished rooms that burned out completely were equivalent to 29 to 45 minutes of the standard test fire. Modern rooms burn faster, fires spread, and a safe may sit in hot debris, so the rating’s hours are a margin, not a promise.

The fire standards at a glance
Five tests cover most fire safes sold today. They share one idea: put the safe in a furnace that follows a standard fire curve, measure the temperature inside, and give it a class for what it can protect and a time for how long. The details differ, and the details are what you’re paying for.
| Standard | Where | Classes | Times | Hot drop test | Main certifiers |
|---|---|---|---|---|---|
| UL 72 | US, Canada | Class 350 (paper), 150 (film, tape), 125 (disks)1 | ½, 1, 2, 3, 4 hours1 | Optional, 30 ft2 | UL |
| JIS S 1037 | Japan | General paper; flexible disk cartridges3 | 30 min to 3 hours for paper3 | Yes, 9.1 m after rapid heating3 | Registered third-party bodies3 |
| EN 1047-1 | Europe | P (paper), D (data), DIS (diskettes)4 | S 60, S 120 (minutes)4 | Yes, “fire shock and impact test”4 | ECB•S5 |
| EN 15659 | Europe | Paper only (“light fire storage units”)6 | LFS 30, LFS 60 (minutes)6 | Not described in the scope | ECB•S5 |
| NT Fire 017 | Nordic countries | Paper, Data, Diskette7 | 60, 90, 120 minutes7 | No7 | SBSC, ECB•S85 |
If you only remember one thing from the table: the number on the label is the time in a furnace, and the class is what the inside temperature was held below. Both have to match what you’re storing.
UL 72: Class 350, 150 and 125
UL 72, “Tests for Fire Resistance of Record Protection Equipment”, is the American standard behind almost every “UL Class 350 1-hour” sticker; the current edition is ANSI/CAN/UL 72:2026.9 A 1993 guide by the US National Park Service quotes its core rule: equipment is classified by an interior temperature limit and a time, and the rating means that limit “is not exceeded” for the stated time, “including the cool down period following the standard fire exposure”.1 That last clause matters. The heat stored in a safe’s walls keeps flowing inwards after the flames are out.
| UL class | Inside limit | Humidity limit | Intended for |
|---|---|---|---|
| Class 350 | 350°F (177°C) | None; the inside can be “at or near 100%” in a fire | Paper records |
| Class 150 | 150°F (66°C) | Below 85% | Paper plus film, photographic negatives, magnetic tape |
| Class 125 | 125°F (52°C) | Below 80% | Also flexible computer disks |
The fire endurance test
UL’s own description: the furnace reaches about 1,000°F (538°C) within five minutes and then follows a set temperature schedule while sensors record the inside temperature and humidity. When the time is up, the burners go off and the safe cools in place before it’s opened to see whether the contents are still usable, not stuck together or crumbling.2 The longer the rating, the hotter the furnace gets by the end:
| Rating | Furnace temperature reached |
|---|---|
| ½ hour | 1,550°F (843°C) |
| 1 hour | 1,700°F (927°C) |
| 2 hours | 1,850°F (1,010°C) |
| 4 hours | 2,000°F (1,093°C) |
The explosion and impact tests
Unless its label says otherwise, every UL-rated unit also has to pass an explosion test, which shows it can take “a sudden exposure to high temperatures” without bursting from a build-up of steam or other gases in the insulation.1 Chubbsafes describes it as putting the cabinet straight into a preheated furnace, because the stresses of rapid heating “can easily cause a poorly constructed unit to fail”.10
The impact test is optional, and the manufacturer has to ask for it.2 Straight after the fire test the hot safe is hoisted 30 feet and dropped, “to simulate a fall from three stories”, inspected, and put back in the furnace for up to another hour.2 A US dealer describes the landing as a pile of broken bricks on a concrete base, and the safe as reheated upside down.11 It’s the test that imagines your safe going through a burning floor, and in a modern house that’s a real prospect (more on that below).
Older UL labels: A, B, C, D and E
If you own an older American safe or fire file, its label may carry a letter instead. Until 1972 UL used letter classes, and the Safe Manufacturers National Association (SMNA) issued its own labels too.1 The Park Service guide gives the equivalents:
- Class A: paper protected in a fire reaching 2,000°F, up to 4 hours (now Class 350, 4 hours).
- Class B: 1,850°F, up to 2 hours (Class 350, 2 hours).
- Class C and D: 1,700°F, up to 1 hour; C with the impact test, D without (Class 350, 1 hour).
- Class E: 1,550°F, up to ½ hour, no impact test (Class 350, ½ hour).1
A label like that tells you what the safe could do when it was new. It doesn’t tell you what it can do now, which is a point we’ll come back to.
Japan: the JIS S 1037 test
Japanese-made fire safes are tested to JIS S 1037, and you’ll see “JIS 1 hour” or “JIS 2 hours” on safes sold well outside Japan.12 It matters because it’s close to UL 72 in spirit. The maker Naiki sets out the method in its catalogue:3
- Standard heating test. The safe is heated along the JIS standard temperature curve for the rated time, then left to cool naturally inside the furnace. For general paper, the inside must stay at or below 177°C (350°F) and newspaper inside must still be readable.
- Rapid heating and drop test. After rapid heating the safe is taken out, dropped from 9.1 m (30 ft), put back in the furnace and heated again for the set time, then cooled in the furnace. It must not burst, must stay locked, and the newspaper must stay readable.
- Grades. Naiki’s label guide shows paper ratings of 30 minutes, 1, 2 and 3 hours, and a 1-hour rating for flexible disk cartridges.
The Eiko catalogue adds a nice detail: the test load is newspaper and crumpled newspaper balls, and the pass is newspaper “legible without appreciable discoloration”.12 Under the JIS certification scheme the fire and burglary tests are done by a registered third-party body.3
Europe and the Nordics: EN 1047-1, EN 15659 and NT Fire 017
European and Nordic tests heat the safe along the ISO 834 standard fire curve, the one used for fire-resisting walls and doors.7 By its formula that curve passes about 945°C (1,733°F) at 60 minutes and about 1,050°C (1,920°F) at 120 minutes, roughly in line with UL’s furnace.13
EN 1047-1: S 60 P, S 120 P, S 60 DIS and the rest
EN 1047-1 covers fire-resisting “data cabinets and diskette inserts”, the heavier European class. It has two test methods, a fire endurance test and a fire shock and impact test, and its grades combine two exposure times (S 60 and S 120) with three protection classes (P, D and DIS) set by the temperature rise and humidity allowed inside.4 So S 60 P is 60 minutes for paper, and S 120 DIS is 120 minutes for the most heat-sensitive media. Diskette inserts (DI 60 P/DIS, DI 120 P/DIS) are boxes that go inside a tested P cabinet of the matching design.4
EN 15659: LFS 30 P and LFS 60 P
EN 15659 is the lighter European standard, for “light fire storage units” that protect paper. The 2009 edition called its two grades LFS 30 P and LFS 60 P; the 2019 edition calls them LFS 30 and LFS 60.6 Its scope is unusually frank: “Protection after the fire exposure of 30 min (LFS 30) or 60 min (LFS 60) is not ensured by this document”, but by EN 1047-1.6 Read that as the standard pointing you to EN 1047-1 if you need protection that holds beyond the rated exposure. Both labels are still on sale, so an older “LFS 30 P” and a newer “LFS 30” are the same grade name.
NT Fire 017: 60 Paper to 120 Diskette
NT Fire 017 is a Nordtest method, last revised in 2003, and it’s refreshingly short.7 Its definitions explain the classes: paper doesn’t lose information below 170°C, “normal magnetic media” below 70°C and diskettes below 50°C. The pass marks follow: the inside may rise no more than 150°C above its starting temperature for a Paper class, 50°C for Data and 30°C for Diskette, for 60, 90 or 120 minutes.7
Two details stand out. The cabinet is tested empty, with the door “latched but not locked”. And the method says the heating ends after a period agreed between the client and the laboratory, and that temperature recording “can be terminated at the same time as the fire test”. There’s no drop test in the method.7 Unlike UL 72, then, NT Fire 017 doesn’t make the cooling period part of the pass.
Who certifies: UL, ECB•S and SBSC
A standard is just a recipe. A certification body is the one who cooks it, checks that the safes in the shop match the one in the furnace, and puts its name on the label. Three names cover most of what you’ll see.
North America
UL
UL Solutions runs the UL 72 tests. A certified safe gets a UL label giving the class and the time rating.2 Look for the UL mark itself, not just the standard’s number.
ECB•S’s own fire guideline shows the sort of detail an independent body insists on. The sample has to carry the most fire-critical lock from the list of locks the series will be sold with, plus any cable holes for alarms or anchoring holes the series has, and only one sample may be in the furnace for a certification test, with all four walls heated equally. New sizes can be added to a certificate without another burn only if at least two sizes have passed and the new one is no more critical.14 SBSC is owned by the Swedish Fire Protection Association together with the Swedish Theft Prevention Association.15 All three publish lists of what they’ve certified, and checking a model against the list is the surest test of a label.
What survives inside: paper, photos and data
Paper is the easy case. It chars at about 420°F (216°C), so a Class 350 safe keeps it below that with some margin.1 It does so partly by steam: the insulation releases water into the safe “to reduce the ability of paper to burn”, and the Park Service guide warns that the humidity inside a Class 350 unit during a fire can be “at or near 100%”. That’s fine for paper and bad for plastic-based media.1
Negatives, slides, film and tape need Class 150 (below 150°F and 85% humidity); old floppy disks needed Class 125 (below 125°F and 80%).1 In Europe the equivalents are the D and DIS classes of EN 1047-1, and in the Nordic method the Data and Diskette classes.47
For USB sticks, memory cards and hard drives there’s a catch. UL 72, as quoted in 1993, says non-paper records are not used as test contents, because testing whether every kind of media survives “is not within the scope” of the standard.1 So the class tells you the temperature and humidity inside, not that your particular drive will work afterwards. Compare it with the storage temperature in the media maker’s own specification, and keep a copy somewhere else.
George Hayter Chubb noticed the same pattern in 1875, long before data safes. Books, he wrote, “will sometimes sustain no injury, whilst loose papers in the same safe may be more or less damaged”, so he advised keeping papers in an inner drawer, and he warned that the steam from a safe’s fire-proofing “often irretrievably damages parchment”.16 A box inside the box is still sensible advice, and it’s exactly how the modern media inserts work.
How to read a fire label
Most labels sit inside the door. Read them in this order:
- Which standard? UL 72, JIS S 1037, EN 1047-1, EN 15659 or NT Fire 017. Liberty Safe’s own advice is that a product quoting only a “fire rating” with no standard or test method is harder to compare, and we’d go further: without a standard, it isn’t a rating in the sense this article means.17
- Which class? 350, P, LFS or Paper for documents; 150, 125, D, DIS, Data or Diskette for film and media.
- How long? ½ hour to 4 hours under UL; 30 to 120 minutes under the European and Nordic methods.
- Impact tested? Under UL and JIS the drop is a separate pass. Older UL letters tell you too: C was impact-tested, D was not.1
- Whose mark? The certification body’s name or logo, ideally with a certificate or file number you can look up.
| Wording you might see | What it tells you |
|---|---|
| UL Classified, Class 350, 1 hour | UL tested it: inside below 177°C for an hour of furnace fire plus cooling. Paper only. |
| Class 125, 2 hours, with impact | Data class, plus the 30-foot hot drop test |
| EN 1047-1, S 120 DIS, ECB•S | European data class, 120 minutes, independently certified |
| EN 15659, LFS 30 P | Light paper unit, 30 minutes (same grade as “LFS 30” since 2019) |
| NT Fire 017-60 Paper | Nordic paper class, 60 minutes; check the certifier |
| “Tested to UL 72” or “in accordance with UL 72” | Says which test, not who did it. Look for the certifier’s mark or a statement that UL classified it. |
| “ETL Verified” | Intertek checked a performance claim; read exactly which claim |
| “Fire resistant to 1,200°F for 30 minutes” | A maker’s own claim unless a standard and certifier are named |
Listed, verified or in-house: what’s the difference?
Here’s the distinction that matters most, and that box art does its best to blur. A listing or classification means an independent body tested samples to a named standard and lists the product. A verification means an independent body checked a particular performance claim. An in-house rating means the maker tested it, or says it did.
Intertek describes its ETL Verified mark as a mark of “performance integrity”, used by manufacturers to show independent testing against criteria set by industry associations or certification programme administrators; its examples are cabling bandwidth and dishwasher cleaning.18 On safes the mark often sits next to a UL one and covers a different claim. SentrySafe’s technical sheet for its F2300 chest, for example, gives “UL Classified 1 hour fire” and “ETL Verified for water submersion”.19 Neither mark is the other. Read which claim each one is attached to.
Wording like “tested in compliance to UL 72” names the method, not the tester. The phrase isn’t a warning sign on its own: Chubbsafes’ data sheet for one filing cabinet says “tested in compliance” in its heading and also states that the product is classified by UL.20 What you want is that second sentence, or the certifier’s mark on the label.
“Put little faith in the tests, either public or private, that are sometimes made, unless they are conducted by persons quite disinterested.”
George Hayter Chubb, 1875
Chubb’s warning is 150 years old and still the whole point. He knew how a “test” could be arranged, by building a safe specially, packing the contents carefully, or “constructing the fire in a particular mode”.16 Independent certification exists to take those choices away from the maker.
What the hours mean in a real house fire
A test furnace is a controlled fire. A house fire isn’t, so it helps to know what researchers have measured.
- Temperature. Early in a fire, the US Fire Administration says a room can be 100°F at the floor and “well over 600 degrees F” at eye level.21 At flashover, when everything in the room ignites at once, NIST lists gas temperatures of 400°C (752°F) or more at the start and about 1,000°C (1,832°F) in a room undergoing flashover.22 That’s the same range as UL’s 1-hour and 2-hour furnace.
- Speed. In UL’s 2012 experiments every room with modern furnishings reached flashover in under five minutes; the fastest room with mid-century furnishings took just over 29.23
- Duration. In 1939 the US National Bureau of Standards burned out a three-room furnished test building. Fires that consumed the contents were equivalent to 29 to 45 minutes of the standard test fire at normal loadings, and slightly less than an hour at the heaviest, furniture-storage load.24 The Bureau itself wasn’t sure those tests were a “realistic upper bound”.24
- Spread. In half of the non-confined house fires reported to US fire departments in 2017 to 2019, the fire spread beyond the room where it started.25
- Collapse. UL found engineered I-joist floors collapsed in under a third of the time of dimensional-lumber floors, and that with firefighters arriving at eight minutes, collapse in a modern house was possible 90 seconds later.23 That’s why the 30-foot drop test exists.
So what do the hours buy? This is our reading of the figures, not a finding of any of the bodies above. A single room burning out may expose a safe for roughly the equivalent of half an hour to an hour of the test fire, which is why a ½-hour rating leaves very little margin. A 1-hour rating covers the 1939 burnouts with some room to spare. Two hours or more buys margin for what the furnace doesn’t model: fire moving from room to room, a heavy fuel load, a slow response in the country, and a safe lying in smouldering debris after it falls. Ratings that count the cooling period (UL 72, JIS) speak to that last risk directly.
One fire only
A rating is good for one fire. The National Park Service guide reports that manufacturers on the US federal supply schedule said their containers keep the UL rating until exposed to fire, after which “the rating is lost” and the container should be replaced.1 Chubb said the same in 1875: after one fire, don’t rely on a safe again until it has been examined and re-proofed.16
Whether a “fireproof” safe really is fireproof, and what owners have found after real fires, is the subject of our separate piece, are fireproof safes really fireproof?
How we got here: from bonfires to UL 72
Victorian safe makers sold fire resistance on stories: survivors of famous fires and staged public burnings, which is the story told in our history of inventing the fireproof safe. Real fires were harsher judges. When London’s Pantechnicon warehouse burned, Chubb wrote, “scarcely one of the many safes survived the conflagration without injury”, and the cast-iron safes were found “cracked and broken like glass”.16
American testing grew out of the same problem. According to a 1959 company history, Charles Meilink of Toledo proved his safes by dragging them behind the works, stacking coal and brick round them “to form a crude kiln” and lighting it. He came to believe safes should be tested “on an industry-wide basis”: the first industry programme began in 1915 and Underwriters’ Laboratories took it over in 1917.26 Those dates come from Meilink’s own account. UL’s own history, written in 1923, puts the start a little earlier: it says manufacturers had begun submitting safes for its label “a little more than a decade ago”, which points to the early 1910s.27 There’s more on the firm in our history of Meilink safes.
- 1875 G. H. Chubb warns against tests not run by “persons quite disinterested”.16
- 1915 First industry-wide safe testing programme in the US, by Meilink’s account.26
- 1917 Underwriters’ Laboratories takes the programme over, by the same account.26
- 1939 The National Bureau of Standards burns out a furnished test building to measure real fire severity.24
- 1972 UL’s letter labels A to E give way to today’s Class 350 style.1
- 1997 European certification of fire and data safes begins, according to the European safe industry body ESSA.28
- 2003 Current edition of the Nordtest method NT Fire 017.7
- 2019 New editions of EN 1047-1 and EN 15659; LFS 30 P becomes LFS 30.46
- 2026 ANSI/CAN/UL 72:2026 published.9
That 1997 date has a second meaning for owners. ESSA says most makers of fire and data safes used asbestos at least until European certification began, so an older fire safe can contain it: read do old safes contain asbestos? before anyone drills or cuts one.28 And an old rating isn’t a current one. The Park Service guide records that cabinets insulated with ordinary Portland cement lost their ratings after about eight years as the water evaporated, and the Japanese maker Naiki gives a fire safe’s service life as 20 years from manufacture, after which its fire performance declines.13 How we research these pages, and what we don’t do, is set out in how we research modern safes.
Myths and facts
A 1-hour safe survives any fire that lasts an hour.
It passed one hour of a standard furnace curve in a laboratory. A real fire can be hotter in places, longer, or end with the safe in debris.
A Class 350 safe protects photos and USB sticks too.
Class 350 allows 177°C and near-100% humidity inside. Film and media need Class 150 or 125, or EN 1047-1 D or DIS.
“Tested to UL 72” means UL tested it.
It names the method. Look for the UL mark or a statement that UL classified it.
An old safe with a fire label still has that rating.
The label describes the safe when new. After a fire the rating is lost, and some insulations lost it with age.
Frequently asked questions
What does UL Class 350 mean?
The inside of the safe stayed below 350°F (177°C) for the rated time in UL 72’s furnace test, cooling period included. It’s the paper class: paper chars at about 420°F.
Is a 30-minute fire rating enough?
It leaves little margin. In 1939 government tests a furnished room burning out matched 29 to 45 minutes of the standard fire, and modern rooms burn faster. On those figures, one hour is a more sensible minimum for papers you can’t replace.
What is the difference between 1-hour and 2-hour fire safes?
Under UL 72 the 1-hour test ends with the furnace at 1,700°F and the 2-hour test at 1,850°F, so the 2-hour safe has passed a longer and hotter fire. Both must keep the inside below the class limit through cooling.
What is the difference between EN 1047-1 and EN 15659?
EN 1047-1 is the heavier standard, with paper and data classes for 60 or 120 minutes and a fire shock and impact test. EN 15659 covers lighter paper units for 30 or 60 minutes.
Does “ETL Verified” mean the same as a UL rating?
No. It means Intertek verified a particular performance claim. Read what the claim is; on some safes the ETL mark covers water resistance and the UL mark covers fire.
