Brief information about standards and markings fo
r clothing that appear in our catalogue EN ISO 11612 - CLOTHING TO PROTECT AGAINST HEAT AND FLAME Clothing approved under the EN ISO 11612 standard provides protection while working in hot environments where there is a risk of sudden contact with a small flame. The clothing also provides various degrees of protection against heat convection and radiant heat for a limited time and intensity. The standard does not apply for welding operations or equipment for fire-fighters. Coding Classes: A, Limited flame spread. B, Convective heat: C, Radiant heat: A1 and A2. No edge ignition, no burn holes, no molten debris and no flaming. After glow time shall be less than 2 seconds. Tests are conducted by applying the flame from the edge of the fabric and from above. A1 is surface ignition and A2 is edge ignition. B1, B2 and B3. The HTI (Heat Transfer Index) indicates how many seconds it takes for the temperature to rise by 24°C. The highest class is B3. C1, C2, C3 and C4. The number of seconds it takes for radiant heat to cause the temperature to rise by 24°C. Highest class C4 D, Molten aluminium splash: D1, D2 and D3. A PVC membrane is attached to the reverse of the fabric sample and the minimum amounts of molten aluminium for each class are then splashed on the sample. The PVC membrane must be undamaged after the test has been carried out. The highest class is D3. D, Molten iron splash: F, Contact heat. E1, E2 and E3. A PVC membrane is attached to the reverse of the fabric sample and the minimum amounts of molten iron for each class are then splashed on the sample. The PVC membrane must be undamaged after the test has been carried out. The highest class is E3. F1, F2 and F3. Indicates the resistance of the fabric in seconds. The fabric shall not ignite or shrink due to temperatures of up to 250°C. (This code was not included in EN 531) Some of the design requirements: - garment must cover whole upper body, neck, arms and legs. Jackets/tops must overlap with trousers/bottoms when the body is moving, e.g. when stretching or kneeling. The following also apply for codes D and E: - No trouser/sleeve cuffs. - all pockets must have flaps that are at least 20 mm wider than the actual pocket opening. This rule does not apply to side pockets on trousers with openings placed at an angle of less than 10° to the side seam. Other: - Codes A, B and C are mandatory, while codes D, E and F are optional requirements. - Specific tests are conducted to ensure that fabrics and seams are able to withstand wear and tear and washing. - CARE INSTRUCTIONS: Follow the washing instructions on the label in your garment. Close zips and buttons before washing the garment. Only use a synthetic detergent. Visually inspect the garment after washing and drying before use. - LOI - (Limited Oxygen Index) This is the minimum concentration of oxygen, expressed as a percentage, that is required to support combustion of a fabric. Wool usually has an LOI of around 25%, which is classed as the lowest level for a low flammability material. EN ISO 11611 - PROTECTIVE CLOTHING FOR USE IN WELDING AND ALLIED PROCESSES (Protective clothing for use in welding and allied processes) Clothing approved under the EN ISO 11611 standard provides protection for those carrying out welding operations. There are two classes - Class 1 and Class 2. (See the comparison below) Code Molten metal: Class 1: 15 drops may cause a temperature rise of 40° on the fabric's reverse side without ignition Class 2: 25 drops may cause a temperature rise of 40° on the fabric's reverse side without ignition Heat transmission: Class 1: At least 7 sec, 20 kW/m² heat flow Class 2: At least 16 sec, 20 kW/m² heat flow Some design requirements: - garment must cover whole upper body, neck, arms and legs. Jackets/tops must overlap with trousers/bottoms when the body is moving, e.g. when stretching or kneeling. - all pockets must have flaps that are at least 20 mm wider than the actual pocket opening. This rule does not apply to side pockets on trousers with openings placed at an angle of less than 10° to the side seam. A ruler pocket with an opening of 75 mm or less may be placed behind the side seam. - trouser legs and sleeves must not be turned up. Other details: - Specific tests are conducted to ensure that fabrics and seams are able to withstand wear and tear and washing. EN 1149-5 - PROTECTIVE CLOTHING - ELECTROSTATIC PROPERTIES - Part 5: Material performance and design requirements (Protective clothing - Electrostatic properties - Part 5: Material performance and design requirements) Clothing approved under the EN 1149-5 standard provides protection against the danger caused by static electricity. Some design requirements: - Buttons, zips and other fastenings must be covered with the anti-static fabric. Other: - When standard EN-1149-1 or EN 1149-3 is mentioned, this designation is for fabric that has electrostatic properties according to the standard. - The use of protective footwear marked with ESD is recommended. 7
