野地消防个人防护设备要求和试验方法第8部分:听力

[中文适用范围]： 本文件规定了野外消防时使用的听力保护装置的最低性能要求和测试方法。 本文件涵盖了个人防护装备 (PPE) 的总体设计、所用材料的最低性能水平以及所用的测试方法。 个人防护装备的目的不是在火灾期间提供保护。 本文件不涵盖用于结构消防（参见 ISO 11999 系列）、用于抵御化学、生物、放射性和核危害或需要反射外表面（参见 ISO 15538）的 PPE。 支持荒地消防的活动，例如砍伐树木和使用电锯，可能需要在本文件中提供的保护之外提供额外的保护。 用户将被引导至与此类保护相关的要求的相关标准。 [外文原描述]： This document specifies the minimum performance requirements and methods of test for hearing protection used when wildland firefighting. This document covers the general design of the personal protective equipment (PPE), the minimum levels of performance for the materials employed and the methods of test used. The PPE is not intended to provide protection during fire entrapment. This document does not cover PPE for structural firefighting (see ISO 11999 series), for use against chemical, biological, radiological and nuclear hazards, or for use where a reflective outer surface is required (see ISO 15538). Activities in support of wildland firefighting, such as the cutting of trees and the use of a chainsaw can require additional protection to that provided in this document. Users are directed to those relevant standards for the requirements associated with such protection.
