Значение и использование

4.1 This specification provides performance properties for textile material and design characteristics for clothing that represent minimum initial requirements for primary and secondary protective clothing.

4.1.1 The initial performance properties have been selected based on state-of-the-art materials in use and have been compared with commercial standards which take into consideration durability in use for specific apparel items.

4.2 Although the specifications for primary protective clothing are written for outer garments, it is recognized that optimum protective performance to severe exposure involves the use of an appropriate system including work clothing underlayers and undergarments.

4.3 It is permissible for one or more of the requirements in Table 1 to be modified upon agreement between the buyer and seller.

Note—Certain treated fabrics exhibit afterglow during the flammability test. This has been judged not a serious hazard. When afterglow occurs, extinguish it after 10 s. Then measure char length and note either the actual time or greater than 10 s for afterglow on the report.

4.3.1 In such cases, any references to the specification shall specify that: “This fabric meets Performance Specification F1002 except for the following characteristic(s).”

Область применения

1.1 This performance specification covers clothing design characteristics that relate to the unique protective requirements of working with molten substances.

1.2 Materials used for both primary protection and for secondary protection are covered.

1.3 Protective properties relate to contact with molten substances and hot surfaces and exposure to open flame and radiant heat.

1.4 This performance specification covers textile materials to be used for protective clothing.

1.5 This performance specification describes the properties of specific textile materials in their fabric or garment composite form as tested by laboratory methods and is not intended to be used to appraise the thermal hazard or fire risk under actual conditions. However, information on the thermal performance of clothing made from textile materials conforming to this specification may be used as an element in thermal risk assessment which takes into account all factors pertinent to the thermal hazard of a particular end use.

1.6 The values stated in SI units are to be regarded as standard. The values given in brackets are for information only.

1.7 The following precautionary caveat pertains only to the test methods portion, Section 8, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
