本文件规定了野外灭火时听力保护的最低性能要求和试验方法。 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。PPE不用于在火灾期间提供保护。 本文件不包括用于结构消防（见ISO 11999系列）、用于对抗化学、生物、辐射和核危害的PPE，或用于需要反光外表面的PPE（见ISO 15538）。 支持荒地消防的活动，如砍伐树木和使用电锯，可能需要本文件中提供的额外保护。 用户可参考相关标准，了解与此类保护相关的要求。交叉引用:EN 352-2EN 352-1ISO/TR 19591EN 352-3EN 50321ISO 13287ISO 15384ISO 1061EN 960ISO 15538EN 458ISO 20345ISO 11613ISO 15383ISO 11999（所有部分）ISO 20344ISO 14529（所有部分）购买本文件时提供的所有当前修订均包括在内。

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.Cross References:EN 352-2EN 352-1ISO/TR 19591EN 352-3EN 50321ISO 13287ISO 15384ISO 1061EN 960ISO 15538EN 458ISO 20345ISO 11613ISO 15383ISO 11999 (all parts)ISO 20344ISO 14529 (all parts)All current amendments available at time of purchase are included with the purchase of this document.
