This standard specifies performance requirements for garments made from flexible materials which are designed to protect the wearer's body, except the hands, from heat and/or flame. For protection of the wearer's head and feet, the only items of protective clothing falling within the scope of this standard are gaiters, hoods and overboots. Protective garments complying with this standard should meet the general requirements of clause 6 - with the exception of 6.6 which is optional based on a User Risk Assessment - and should also meet at least one of the other heat transmission requirements of clause 7 according to the intended use of the garment claimed by the manufacturer. This standard does not apply to protective clothing that is manufactured to the requirements of the other standards that cover clothing to protect against heat and flame.
