This Standard specifies the minimum requirements and test methods for assessing protective clothing that is intended to be worn while engaged in interior attack, structural firefighting and associated activities where there is a risk of exposure to heat or flame or both.
This Standard covers the general clothing design, the minimum performance requirements of the materials used, and the test methods for determining these.
This Standard does not cover special clothing for use in other high risk situations such as specialized firefighting clothing (e.g. proximity firefighting clothing), or clothing for use in brush, wildland, or forest firefighting. It does not address protection for the head, hands and feet or protection against other hazards, e.g. chemical, biological, radiation and electrical hazards. These aspects may be dealt with in other Standards.
