The key reason for wearing FR clothing is to ensure that the garments do not catch fire and/ or to limit flame spread, thereby giving time to react in the event of an accident. All quality PPE Clothing (PPE=Personal Protective Equipment) follows the PPE Directive 89/686/EEC and the latest European (EN) standards for PPE Clothing covered by the Directive. From April 21st 2018 the new PPE Legislation (EU)2016/425 is in force and there will be a transition period to replace all old certificates from the PPE Directive to the new PPE Legislation.
FLAME RETARDANT ANTI-STATIC PROTECTIVE CLOTHING – more about this category of protective safety clothing…

There are 3 categories within the PPE Directive/PPE Legislation;
Category I – low risk of injury (e. g. rain protection EN 343)
Category II – risk of injury (e. g. EN ISO 11612 A, B, C, Heat & Flame)
Category III – high risk of injury (e. g. Electric Arc IEC 61482-2, Molten Metal EN ISO 11612 D3, E3)

Tranemo, for example, Category III garments have a production quality monitoring system (11B according to the Directive/Modul D according to the Legislation) to ensure that the garments are safe to use. They are marked with CE0403 by our Notified Body, FIOH.

Below are the symbols and explanations of the standards used in our Flame Retardant clothing.

Symbol CE


All Tranemo PPE Clothing are CE marked. The CE marking indicates that a Notified Body has CE type examined these garments according to the PPE Directive 89/686/EEC or the PPE LEGISLATION (EU)2016/425.
On Tranemo garments you will find this symbol on the inside CE label. The CE label also shows which standards and classes the garments are approved for.

Info symbol


When you find this symbol on the CE label inside the PPE garment it indicates that there is additional information from Tranemo attached to your PPE garment. This information must be read before you start using the garment to ensure that it is worn correctly and giving the optimum protection in the workplace.

Symbol IEC 61482-2

IEC 61482-2

This standard specifies PPE Clothing when there is a risk of an Electric Arc – for instance when working with electricity on open equipment or maintenance / switching work. Electric Arc garments come under PPE Directive / PPE Legislation Category III . Fabric properties and garment design are important parameters in the certification process of Electric Arc garments.

Tranemo Electric Arc garments are marked with IEC 61482-2 which includes both test methods for Electric Arc: EN 61482-1-1 “Open Arc test” which involves a medium voltage range (>1 000V) and EN 61482-1-2 “Box test” which involves a low voltage range (400V). Both tests simulate different levels of risks.

EN 61482-1-1 Open Arc test – this tests the protection level of the garment by using an open arc, this test method is similar to the American Electric Arc Standard ASTM F1959. The open arc test results in an ARC RATING; ATPV value (Arc Thermal Performance Value) and/or EBT50 value (Energy Break Open Threshold). This is an Arc Rating system for the FR fabric/fabric layers. The result is given in cal/cm² and means that at this energy the garment is predicted to protect from a second-degree skin burn (with a 50% probability). The value helps you to choose the right level of protection.

This test also gives a HAF-Value (Heat Attentuation Factor). HAF specifies the protection ability of the garment/garments to block and protect against heat transfer through the garment from an Electric Arc. 2-layer and 3-layer systems increase the value due to the air gap in between the fabric.

Below showing two examples of how different garment combinations gives a higher HAF-value:HAF-value
Note: To follow the demand in the PPE Directive/PPE Legislation with zero probability of injury, a new value is added to the updated version of EN 61482-1-1 in 2018 called ELIM = Energy Limit.
The American NFPA 70E Standard for electrical safety in the workplace is a consensus standard on how to protect workers from the hazards of an Electric Arc. NFPA is designed to help employees and workers to understand electrical hazards, it helps with: hazard assessment, arc rated PPE selection and electrical safe work practices. The Arc Rating is divided into four PPE Categories, PPE stands for Personal Protective Equipment. Tranemo normally recommends that the outer layer reaches 8 cal/cm² (i.e. PPE 2/CAT 2).

  • PPE 1 – CAT 1 – 4-8 cal/cm²
  • PPE 2 – CAT 2 – 8-25 cal/cm
  • PPE 3 – CAT 3 – 25-40 cal/cm²
  • PPE 4 – CAT 4 – >40 cal/cm²

EN 61482-1-2 Box test – tests the protection class of the garments by using a constrained and direct arc.

  • Class 1 – 168 kJ (4 kA, 400V)
  • Class 2 – 320 kJ (7 kA, 400V)

A single layer garment will in most cases pass class 1. To reach class 2, a two or three-layer system (or a thicker garment such as a winter garment) is needed.

Symbol EN ISO 11612

EN ISO 11612

This standard specifies PPE Clothing when working where there is a risk that the garments will come into contact with heat and flame. The standard is divided in different categories, where the code letters show which heat and flame requirements the garment needs to fulfill. At least two categories must be tested to be able to CE mark the garments. Code letter A1 and/or A2 is mandatory and the result is included on the CE label together with this symbol. The code letters are classified in different levels where the highest number is the highest tested level. The design of the garment is also a parameter in the CE marking for heat and flame garments.

When the fabric is tested for convective heat (B) and radiant heat (C) you get two values. The first value is the time it takes for the skin temperature underneath the fabric to increase to 12°C, this is when you sense the heat. The second value is the time it takes for the skin temperature to increase to 24°C, this is when you risk a second-degree burn. The time for the temperature to increase from 12ºC to 24ºC is the time you have to react and move away from the heat source.

If the fabric can resist molten aluminum it will normally also be acceptable against molten aluminum bronze and molten minerals. Also if the fabric can resist molten iron, it will normally be acceptable against molten copper, molten phosphor bronze and molten brass. If working with other molten metals or alloys than aluminum (D) or iron (E), please contact us and we will discuss the best fabric / garment solution for your risk assessment.

  • A1, A2 – Requirements for limited flame spread; A1: Surface ignition. A2: Edge ignition.
  • B (1-3) – Protection against convective heat and open flames
  • C (1-4) – Protection against radiant heat
  • D (1-3) – Protection against molten aluminum splash
  • E (1-3) – Protection against molten iron splash
  • F (1-3) – Protection against contact heat

The American Standard for protection against heat and flame is called NFPA 2112. The biggest difference in the American Standard is the char length test and that some tests are done after 100 washes. EN ISO 11612 is an international standard also approved by the US.


LOI means the minimum concentration of oxygen (expressed as a percentage) that would be required to support combustion of a fabric. It determines the protection of the garment regarding relative flammability and should be over 25%.
We test the LOI value on our fabrics and show this on the outside FR label. The LOI value is one way to indicate the level of FR protection a garment provides and it makes it easier for the user to compare and choose the right level of protection.

Symbol EN 14116

EN ISO 14116

The standard is often used for PPE clothing and accessories with lower level Flame Retardant protection, such as High-Visibility vests, rainwear, kneepads and socks.
It is divided into three classes, where index 3 is the highest level. Index 3 garments should be worn in combination with EN ISO 11612 garments. (It is important to note that Index 1 garments should not be worn next to skin.) This standard does not have a dedicated Symbol/Pictogram. Tranemo uses the flame symbol to indicate it is a FR garment.

Symbol EN 1149-5

EN 1149-5

This standard specifies PPE Clothing used in explosive environments (i.e. ATEX) where there is a risk that the garments could create sparks (source of ignition), which in turn could ignite explosive materials.
To certify garments to this standard, the Anti-static properties of the fabric are tested according to EN 1149-1(surface resistivity) or EN 1149-3(charge decay). The design of the garment is also a parameter in the certification and CE marking of Anti-static/ATEX garments.

Symbol EN ISO 11611

EN ISO 11611

This standard specifies PPE Clothing used in welding work or allied processes where you have the risk of spatter (small splashes of molten metal), short contact with flame, radiant heat from the arc, and risk of electric shock by short-term, accidental contact with live electrical conductors (at voltages up to approximately 100 V DC in normal conditions of welding).
The standard is divided in two different classes with different levels of protection. The welding function of the fabric is tested with 15 drops (class 1) or 25 drops (class 2) of molten metal. The design of the garment is also a parameter in the CE marking of welding garments.

  • Class 1 – Protection against less hazardous welding techniques and situations, causing lower levels of spatter and radiant heat.
  • Class 2 – Protection against more hazardous welding techniques and situations, causing higher levels of spatter and radiant heat.
Symbol EN 13034

EN 13034 TYPE PB[6]

This standard specifies PPE Clothing used where there is a risk of a potential exposure to a light spray, liquid aerosols or low pressure, low volume splashes against which a complete liquid permeation barrier (at a molecular level) is not required.
This standard tests four different chemical types: Acid, Alcaline, Aromatic Hydrycarbone and Alcohol. At least two out of four chemicals must pass the test to be able to certify and CE mark the garments with this symbol and the highest level is 3. The design of the garment is also a parameter in the CE marking for chemical protection garments.

Chemicals that are tested in accordance to EN 13034: H2SO4 30% (Sulphuric acid), NaOH 10% (Sodium hydroxide also called lye and caustic soda), O-xylene, Butanol Please note that FC finish used for EN 13034 certification needs to be re-activated by heating the garment after each wash cycle. The garment must also be re-impregnated when necessary. Industrial Laundries have processes for doing this in the correct way. If you are working with other chemicals or other concentrations of the above chemicals, please contact us for information on the best fabric / garment solution for your risk assessment.EN13034 table

Symbol EN ISO 20471

EN ISO 20471

This standard specifies PPE Clothing used where the wearer needs to be visible at day and night and where there is a risk from moving vehicles.
This standard has three different levels covering three different risks and the maximum level is class 3. The figure below indicates the area of fluorescent and reflective material within the garment. To certify and CE mark a garment with this symbol, it must achieve one of these levels. The fabric and reflective tape is tested after 5 laboratory washes. The design of the garment is also a parameter in the CE marking of High Visibility garments.

Material area in m²Class 1Class 2Class 3

If a garment is certified as a class 3 system it is indicated with the below symbols on the inside CE-label.

The American Standard for High-Visibility clothing is called ANSI/ISEA 107. EN ISO 20471 is an international standard also approved by the US.

Symbol EN 343


This standard specifies PPE Clothing used for working in rain or snow, fog and ground humidity.
The garment and seams are tested for water penetration (waterproofness) which gives a class 1,2 or 3 and water vapor resistance (breathability) which also gives a class 1,2 or 3, where class 3 is the highest level in both cases. The garment must achieve a result on both tests to be CE marked with this symbol. The breathability of the garments are affected by its construction and it is common for an unlined garment to reach EN 343 class 3:3 (same as the outer fabric) whilst lined garments in the same outer fabric only achieve EN 343 class 3: 1. In these cases it is the lining in the garment that affects the permeability of water vapor resistance (breathability).
Waterproofness can also be measured according to EN 20811, giving a result in millimeters of water column (mmH2O) or Pascal (Pa). Tranemo designates garments with a water column > 5000 mm (50000 Pa) as wind and waterproof. This gives a good protection in intermittent rain or inclement weather. In heavy or prolonged periods of heavy rain, traditional laminated rainwear is recommended.

Symbol EN 342


This standard specifies PPE Clothing used when working in cold environments.
It requires tests of resultant effective thermal insulation (value in m²K/W), air permeability (shown as class 1,2 or 3) and resistance to water penetration (shown as class 1 or 2). The garment must achieve results on thermal insulation and air permeability to be CE marked with this symbol – the water penetration test is optional.
