DIN ISO 10109:2015-12

Optical and photonic instruments including additional assemblies from other fields (e. g., mechanical, chemical and electronic devices) are affected during their use by a number of different environmental and handling parameters which they are required to resist without significant reduction in performance and to remain within defined specifications. This is what the manufacturer attempts to ensure and the user expects to receive. This expectation can be assessed by exposure of the instrument to a range of simulated environmental parameters under controlled laboratory conditions. The cumulative combination, degree of severity, and sequence of these conditions can be selected to obtain meaningful results in a relatively short period of time. This International Standard contains tables for environmental tests and test parameters which can be used as a guideline for the selection of environmental tests. These include the selection of standardized tests according to ISO 9022 as well as additional parameters, whether not described in ISO 9022 or individual parameters necessary for the optical or photonic instruments. Ultimately, these tables propose the requirements to be met with regard to the reliability of the optical, mechanical, chemical and electrical properties or performance characteristics of the instruments when exposed to environmental influences. Environmental test methods, as specified in ISO 9022 (all parts), can be assigned to the various areas of application for the purpose of ascertaining the suitability of the instruments in the respective area of application.
