What is a safe?

Every safe offers a certain level of burglary resistance, but what really matters is whether the safe offers enough resistance to keep the burglar out for long enough.
1. What is a security safe?
A security safe is a safe that delays against unauthorized access to valuables (contents) in an unmanaged situation.
Burglary threat levels
- Undefined - we do not know in advance which type of burglar will visit!
- Depending on the situation - difficult to access or easy (think of burglary detection, basement, stair cupboard, other obstacles)
- Loot dependent - is there much or little to get?
- Experience - is the burglar a casual thief or organized criminal?
- Inside information - does the burglar know which safe and type is present, or does he have no idea?
- Available tools - light or heavy tools, and many or few tools?
2. How is the burglar resistance of a safe measured? 
There is only one way to measure the burglary resistance of a safe ... and that is to attack!
This done by a test institutes that has extensive knowledge, skills and resources. In a laboratory the safes and their constructions are studied, analyzed and attacked.
Test institutes
In Europe there are a number of leading test institutes, these are:
- VdS, Germany
- CNPP, France
- Istituto Giordano, Italy
- SP, SBSC, SSF, Sweden
The above test institutes have been approved and accredited by ESSA to issue ECB.S certificates. The ECB.S certificate is the highest attainable for safes and guarantees independently controlled quality.
In addition, these test institutes have decades of knowledge and expertise for testing safes for burglary resistance. During the testing, the worst case situation is assumed, the so-called 'worst case':
- Full knowledge
- Free choice of method & tools
- Optimal conditions
- Stops for rest and consultation
- LPCB, England
- Czech Tresortest, Czech Republic
- IMP, Poland
Practice has shown that test institutes that are not ESSA approved have a higher rating for safes. The testing of security safes is a human intervention (carried out by humans) and can therefore differ per institute. There are examples of safes that are Grade V EN 1143-1 marked and are Grade II certified in an ECB.S accredited institute. See the ECB.S press release January 2010: Black sheep fail the safe test
European standards for safes are performance standards
In contrast to obsolete standards such as NCP and VDMA, the European Standards are performance standards. This means that on the basis of the tools used and the time required, a score is obtained to make an opening 1) . The higher the score, the higher the rating of the safe.
Note
1) By creating an opening, the European Standard defines a hand hole (125cm 2 , round, square or rectangular) or a manhole (1000 cm 2 round, square or rectangular) or safe door 300 mm open.
3. Standards for security safes
For burglary safes, a distinction is made between the following security standards:
- EN 14450 European Standard for private safes Security Level S1 and S2 2)
- EN 1143-1 European Standard for safes Grade 0 to class VI 3, 4)
- EN 1143-2 European Standard for Deposit Safes Grade DI to Class DIV 3)
Comments
2) For EN 14450: 'Security Level' is also called 'Class'.
3) For EN 1143-1 and EN 1143-2: 'Grade' is also referred to as 'Class', 'CEN' or 'Eurograde'. For EN 1143-1 and EN 1143-2, the Grades are indicated with a Roman sign (I, II, etc.)
4) For EN 1143-1, the classification continues to Grade X. These higher classes are used for safe rooms. Safes go up to Class VII.
The NCP and VDMA standard has become obsolete and has been replaced by European Standard EN 14450. However, this indication is still frequently used to indicate the safety of a safe. This designation will expire completely on 1 January 2016. Please note: this concerns safes built according to regulations (construction characteristics). These have not been tested and are not certified.
4. What about the lock on a safe?
The European Standard for safes also defines how much and to which classification safe locks must comply. Depending on the class of the security safe, 1 or 2 locks are used that must comply with EN 1300 (European Standardization for safe locks).
Standardization | Lock required according to | Number |
EN 14450 | EN 1300 | |
S1 | class A. | 1 |
S2 | class A. | 1 |
EN 1143-1 & EN 1143-2 | ||
Grade 0 | class A. | 1 |
Grade I. | class A. | 1 |
Grade II | class A. | 1 |
Grade III | class B | 1 |
Grade IV | class B | 2 |
Grade V. | class B | 2 |
Grade VI | class C. | 2 |
Note
To comply with certification, the manufacturer must install a lock in accordance with the standardization requirement. In practice, you do not have to take into account whether the lock is certified. This is always the case with a European certified safe!
5. Anchoring a security safe
A safe that weighs less than 1000 kg must be anchored to the European Standard for safes for maximum protection. In order to actually obtain insurance coverage, it is often also a requirement of the insurance company.
Incidentally, the European Standards for security safes describe the resistance the anchoring must have. This is also part of the test procedure!
Anchoring methods
Anchoring to a concrete floor or wall ensures the best possible fixation. In such a situation, mechanical anchors are sufficient. In exceptional situations, where the thickness of the floor or wall is limited, or of a lower quality, chemical anchoring can often be a good alternative. Of course, the quality of the confirmation is ultimately determined by the 'weakest' link.
Anchoring yourself? Is easily possible if you have the right tools and knowledge. For (small) home safes, this is even very easy to do yourself. Larger and especially heavier safes are usually installed by a professional installer. This not only ensures correct anchoring, but also ensures safe placement. If you want to have the installation carried out, go to: placing and anchoring the safe .
6. Insured value & value storage
Insured value
Insurers link a present value to the different resistance classes as an indication of coverage.
This is based on a security safe that is located in an uninhabited, unguarded and unsecured building within the built-up area. An insurer may deviate from the coverage indication due to other and additional security measures taken.
It is always advisable to contact your insurance company if you want to store specific valuables with high value or a lot of cash.
Value storage
The tables below are valid for the UK. See also ECB website. Insurance amounts in Europe for other countries in Europe.

Grade VI | - | £150,000 | £1.500,000 |
Grade VII | - | in consultation with the insurer |
7. How do I recognize a good security safe?
Construction features
There are a number of external construction features by which you can recognize a burglar-resistant safe.
- A security safe has a solid lock with large shots
- There is a relatively high threshold from the safe door to the frame in which the safe door falls
- Thick walls and safe door
- Anchoring holes in the bottom and / or back wall
- Integrated thief claw on the hinge side of the safe door
Incidentally, there are many (more) invisible features that make a good security safe. We can think of:
- Special barrier filling
- Anti-drilling profiles in the safe walls
- Anti-cutting torch plates
- Use of special and hard metals such as manganese steel, carbide plates
- Glass plates that are connected to active emergency shots
Certificate and type plate in the safe
Naturally, a certificate is part of a tested and certified safe. A paper certificate is issued to the manufacturer. With this certificate, the manufacturer is authorized to affix the nameplate in the relevant safe. The manufacturing process is supervised by the certification body and random checks are carried out to ensure the correct manufacturing method. In addition, the manufacturer must comply with the necessary ISO quality procedures.
The safe itself is provided with a label on the inside. This is an (aluminum) nameplate and placed on the back of the safe door. It states whether the safe has been produced and tested under controlled manufacturing according to the specified resistance class.

It is often thought that every safe is fire resistant. That is possible, but not by definition. A safe is only truly fire resistant if it has been tested and certified according to a fire-resistant standard.
In this blog article we will discuss what kind of safe a fire resistant safe is, what you can expect from it and what you should pay attention to during purchase. We also discuss the various standards for fire-resistant safes. There are also (major) differences in this. If in doubt, always contact the specialist.
1. What is a fire resistant safe?
A fire resistant safe is a safe that protects paper, digital and data media against the consequences of a fire for a certain period of time:
- Temperature
- Moisture
- Debris
Wall-mounted fire-resistant safe
The wall construction of a fire-resistant safe is of crucial importance. It must withstand the heat during a fire to protect the contents of the safe.
Depending on the items stored in the safe, the temperature should not exceed:
- 177 ° C for paper such as documents, files, contracts, certificates, diplomas
- 75 ° C for data media such as USB stick, DVDs, CDs, memory cards
- 52 ° C for data media such as backup tapes, floppies
For digital and data media, the relative humidity must not exceed 85%.
Originally, manufacturers produced "P", "D" and "DIS" fire resistant safes to protect the above media in a fire. Because different plastics are used in USB sticks, memory cards, etc. and they can deform above 52 ° C, a "DIS" fire resistant safe is always recommended. This has resulted in manufacturers phasing out the "D" fireproof safes.
In practical terms, we are still talking about 2 types of fire-resistant safes:
Note
Designation "P" and "DIS" are the result of European Standard EN 1047-1. Other standards use a different designation for fire-resistant safes for paper and data media. See 3. table fire resistant standards for the indications per standard.
2. How is the fire resistance of a safe measured?
There are several tests that are performed on fire resistant safes to measure fire safety.
Fire endurance test
A very serious fire is simulated during the fire duration test.
- Phase 1: The safe is fitted with thermocouples (temperature meters) on the inside, placed in the oven and exposed to very high temperatures. For the test period, the temperature is between 850 ° C - 1100 ° C *.
- Stage 2: The safe remains in the oven until the thermocouples register a visible temperature drop. During this phase, the internal temperature must be maintained below 177 ° C. Once cooled, the safe contents are checked for usability.
* Temperature depends on test performed. See table fire resistant standards.
Fire drop test
During the fire drop test, the strength (power) of the safe is measured to withstand the simulated effect of falling through a burning and collapsing building.
- Phase 1: The safe is fitted with thermocouples (temperature meters) on the inside, placed in the oven and exposed to a temperature of approximately 1000 ° C.
- Phase 2: The safe is taken out of the oven, lifted to a height of approximately 4 or 9 meters * and dropped onto a bed of rubble.
- Stage 3: The safe is immediately returned to the oven for another 30 minutes.
- Stage 4: The safe remains in the oven until the thermocouples register a visible drop in temperature. During this phase, the internal temperature must be maintained below 177 ° C. Once cooled, the safe contents are checked for usability.
* Height depends on the test performed. See table fire resistant standards.
Test institutes
Internationally, there are a number of leading test institutes, these are:
- VdS, Germany
- SP, Sweden
- UL, United States
- JIS, Japan
VdS and SP are approved and accredited by ESSA to issue ECB.S certificates.
Other fire tests / test institutes include:
- ETL, United States
- KS, South Korea
- GB16810-1997, China
Contrary to testing burglar-resistant safes, testing fire-resistant safes is not a human intervention. However, this does not mean that all test institutes can simply be compared with each other. The highest requirements are also placed on ECB.S certified safes during a fire test.
In-house fire test
For product development, manufacturers test their products themselves to determine performance and optimize safes. In itself fine, but such tests are not under the independent and controlled supervision of neutral institutes.
3. Table fire resistant standards
The following standards are applied internationally. If one of these tests is carried out by a VdS, SP, UL or JIS), a correct execution of the fire test is ensured. The test results are reliable. Independent experts recommend a fire-resistant safe certified to one of these standards and test institutes.
Norm | Temperature duration test | Drop test | Paper | Data Media |
EN 104701 | 1090 ° C | Yes, 9.15m |
|
|
EN 15659 | 850 ° C | No |
|
N / A. |
UL 72 | 1000 ° C | Yes, 9m (optional) |
|
|
JIS (S1037) | 927 ° C | Yes, 4m |
|
N / A. |
NT Fire 017 | 1090 ° C | No |
|
|
Attention!
The following standards are applied nationally or locally by, for example, manufacturer or supplier. Testing is also done as "in-house testing" for eg product development. Today, there are many products on the market with these labels and certification. They are real tests, but not independent and not checked. If you do not want to take any risks with the choice of a fire resistant safe for the safe storage of your personal belongings or business criticism documents and data media, always choose a fire resistant safe certified of one of the above standards!
Note
- Data media are most vulnerable storage media, such as: backup tapes, floppy disks, photo negatives, (traditional) hard disks, USB sticks, CDs, DVDs, memory cards
- For a real fire resistant safe choose a safe certified according to EN 1047-1, EN 15659, UL72, JIS (S1037) or NT Fire 017.
- For the best fire resistant safe, choose a safe certified to EN 1047-1 or UL72.
- A fire-resistant construction according to DIN 4102 does not yet make a fire-safe. At most, it provides a fire delay of a few minutes. See also our blog article: The fire safety of DIN 4102
4. How do I recognize a fireproof safe? Construction features.
There are a number of external construction features by which you can recognize a fireproof safe.
- Fireproof safes generally have a thick wall structure and a thick safe door. The use of different barrier materials increases the thickness of the wall and the door, but keeps heat out as much as possible.
- The frame of the safe door is provided with a kind of tape (often black). This tape swells in the event of a fire and provides extra sealing
- For fire resistant data safes, a wooden inner box is often used. This is wood-colored or lacquered wood. A wooden inner box can provide a watertight seal.
Nameplate in safe
You can recognize a certified safe by the label on the inside of the safe. This is nameplate (aluminum or sticker) and placed on the back of the safe door. It states whether the safe has been produced and tested under controlled manufacturing according to the specified resistance class.
Norm | Temperature duration test | Drop test | Paper | Data Media |
GB16810-1997 | 945 ° C | No |
|
N / A. |
ETL | 760 ° C | Yes, 4.5m | N / A. |
|
MTS DIP 120-60DM | 945 ° C | No | N / A. |
|

![]() |
S120DIS according to EN 1047-1 | 120Paper according to NT Fire 017 |
Quality control
A paper certificate is issued to the manufacturer. With this certificate, the manufacturer is authorized to affix the nameplate in the relevant safe. The manufacturing process is supervised by the certification institute and random checks are carried out to ensure the correct manufacturing method. In addition, the manufacturer must comply with the necessary ISO quality procedures.
5. Is a fireproof safe waterproof?
A fire resistant safe is by definition not watertight. With a fire-resistant safe, a distinction is made in which items can be stored. As described above, in addition to a maximum temperature, the humidity for digital and data media should not exceed 85%. This requirement does not apply to paper (documents, files, certificates, contracts, etc.) because they are not destroyed if they get wet.
To meet the moisture requirement of data media, extra (rubber) strips are placed in the inner box so that moisture cannot penetrate. Extinguishing water is kept 'outside' in this way.
6. What do we do with the safe after a fire?
After a fire, a safe looks battered and can sometimes hardly be recognized as a safe. The fire burned the paint completely and a (possibly) plastic keyboard was melted. To open the safe, it must be pried open and / or drilled open. However, if all goes well, the items in the safe are still usable after the fire.
After a fire, the safe itself is no longer usable. The barrier materials have changed state and no longer have the absorption capacity as in the original state. The safe has done its job and is no longer usable. A new fireproof safe will once again protect your valuables in a fire!
