本文件规定了野地消防头盔的最低性能要求和试验方法。 本文件涵盖荒地消防头盔的总体设计、所用材料的最低性能水平以及所用的测试方法。个人防护设备（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。

This document specifies the minimum performance requirements and methods of test for helmets used for wildland firefighting. This document covers the general design of wildland firefighting helmets, the minimum levels of performance for the materials employed and the methods of test used. The personal protection equipment (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.
