标准摘要
[中文适用范围]： ISO 20711:2017 规定了光学、机械、化学和电气特性或性能数据抵抗环境影响的仪器要求，从而确定了地理和技术应用领域。它适用于消费者用望远镜系统及其配件，如狩猎和体育用品。ISO 9022 相关部分规定的环境测试方法被分配给各种应用领域，以确定仪器在其各自应用领域的适用性。本文件是仪器标准中环境要求与环境测试规格的基础。如有必要，这些要求和测试可在仪器标准中进行修订。本文件不处理仪器从制造商到用户运输期间包装的要求。 [外文原描述]： ISO 20711:2017 specifies requirements to be met with regard to resistance of the optical, mechanical, chemical and electrical properties or performance data of instruments to environmental influences and hence determines geographical and technical areas of application. It applies to consumer telescopic systems and accessories, such as hunting and sporting products. Environmental test methods as specified in relevant parts of ISO 9022 are assigned to the various areas of application for the purpose of ascertaining the suitability of the instruments in their respective area of application. ISO 20711:2017 is the basis for the specification of environmental requirements and environmental tests in instrument standards. If necessary, these requirements and tests can be amended in the instrument standards. ISO 20711:2017 does not deal with the requirements to be met by the packaging of the instrument during transport from the manufacturer to the user. NOTE Nominal values of properties and performance characteristics as understood by this document are predetermined by specifications provided by the manufacturer, technical terms of delivery and instrument standards.
