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 to attain a temperature rise of 24°C. Highest class 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 design requirements: - The garment must cover the 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: - trouser legs and sleeves must not be turned up. - 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 details: - 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 meet the requirements for strength and dimensional stability to 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. Check the garment after washing and drying before use. 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) Coding 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: - The garment must cover the 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: - Specific test methods are used to ensure that fabrics and seams meet the requirements for wear, 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 the EN-1149-1 standard or the EN 1149-3 standard is mentioned, this is the designation of fabrics that meet the standard's requirements for electrostatic properties. - The use of protective footwear marked with ESD is recommended.
