Standard Performance Specification for Protective Clothing and Materials for Use by Workers Exposed to Specific Molten Substances and Related Thermal Hazards

Importancia y uso:

4.1 This specification establishes minimum design, performance, and labeling criteria for both primary and secondary protective clothing for use in operations involving molten substances and related thermal hazards.

Note 1: Standardized molten splash testing of both primary and secondary protective materials and garments as listed in this specification utilize pure molten materials, typically iron or aluminum. In practice, users of protective clothing for metal splash protection may routinely work with alloys. Protective clothing covered by this specification may or may not perform similarly with alloys of various metals. The entity specifying the protective clothing shall determine if the protective clothing is appropriate for their specific alloy.

4.1.1 Requirements are specifically established for materials used in the construction of primary and secondary protective clothing on the basis of performance attributes that are considered important for worker protection. In some cases, different minimum levels for the same performance properties are set between primary and secondary protective clothing due to the differences in the expected performance for these two types of protective clothing.

4.1.2 Additional requirements are established for primary and secondary protective clothing items in terms of the minimum design characteristics and performance features for other materials and components used in the construction of the clothing.

4.2 This specification can be applied to either protective clothing materials or protective clothing, or both.

4.2.1 The application for protective clothing materials involves meeting the respective requirements for either primary or secondary protective clothing materials found in Section 5.

4.2.2 The application for protective clothing involves meeting the respective requirements for either primary or secondary protective clothing found in Section 6, which includes construction of the clothing with protective clothing materials that meet the requirements in Section 5.
