BS ISO 20711:2017 pdf download – Optics and photonics Environmental requirements – Test requirements for telescopic systems
1 Scope
This document 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 geograp hi cal and technical areas of appl i cat ion. It applies to consumer telescopic systems and accessor ies , such as hunting and sporting products. Environmental test methods as specified in relevant parts of I SO 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.
This document 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 .
This document 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 characteristi cs as understood by this document are predetermined by specifications provided by the manufacturer , technical terms of delivery and instrument standards.
