Flame retardant workwear is a kind of protective clothing which can prevent itself from being ignited, flaming and smoldering in a certain period of time after contacting flame and hot objects. Flame retardant workwear is an important personal protective equipment, which has been widely used in petroleum, chemical industry, metallurgy, shipbuilding, fire protection, national defense and places with open fires, sparks, molten metals and inflammable substances.
While the market of flame retardant workwear is expanding constantly, the corresponding technical regulations are needed to evaluate its flame retardant performance. Today we briefly introduce EN ISO11611, one of the EU flame retardant workwear testing standards.
EN ISO 11611 replaced the original standard EN 470-1, mainly for welding and similar flame retardant workwear design, materials, safety, size marking and marking, etc. made specific requirements, EN ISO 11611 is divided into Class 1 and Class 2 two security levels. Relevant flame retardant tests are carried out according to ISO 15025:2000 standard, including surface and bottom burning test methods for flame retardant workwear fabrics. According to the type of materials, one or two methods can be chosen for testing.
For the surface burning test of flame retardant workwear fabrics, the materials must meet the following requirements:
(1) The flame retardant test kit sample can not be ignited and spread to the edge of the fabric or the upper end of the fabric.
(2) no flame retardant workwear sample can be formed after ignition.
(3) any flame retardant workwear sample can not be ignited droplet or melt falling after ignition.
(4) the average burning time of the flame retardant workwear should be less than or equal to 2S.
(5) the average smoldering time of the flame retardant workwear should be less than or equal to 2S.
For the bottom combustion test, the material must meet all the requirements above (2).
Xinxiang Yulong Textile Co., Ltd. was founded in 2002, for many years focused on the production and processing of flame retardant workwear.
