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 m²   Class 1               Class 2      Class 3

Fluorescent                    0,14              0,50                   0,80

Reflective                       0,10              0,13                   0,20

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

RIS-3279-TOM ISS 1 (GO/RT 3279) 

Railway Group High-Visibility Standard for UK. Defining the High-Visibility orange and the design of the garment i.e. fully fluorescent orange, no contrast colour and defined placement of the reflective tape.

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).

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.

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, Alkaline, Aromatic Hydrocarbon 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.

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.

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.

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.

EN ISO 11612 


This standard specifies PPE Clothing when working where there is a risk that the garments will come in to 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 fulfil. 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 aluminium it will normally also be acceptable against molten aluminium bronze and molten minerals. If the fabric can resist molten iron, it will normally be acceptable against molten copper, molten phosphor bronze and molten brass.

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 aluminium 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%.

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.
