DIN Standards Committee Optics and Precision Mechanics

Overview

Optical instruments including their additional assemblies from other fields (for example, 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 not described in ISO 9022 and necessary for the optical or photonic instruments. Ultimately, these tables specify 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. Technical requirements as given in the tables of this International Standard are abbreviated and the reader has to consult the referenced standards (that is the relevant ISO 9022 part) for the full specification of the technical requirement. For the purposes of ISO 10109, nominal values for properties or performance characteristics are understood to be the manufacturer’s internal technical data and do not directly reflect manufacturer's product specifications. The document presented here as a standard represents a consolidation and fundamental revision of the previous parts of the DIN ISO 10109 series of standards in the form of guidance for the selection of environmental tests for all types of devices in the field of optics and photonics. The committee responsible for this standard is Working Commitee NA 027-01-02-03 AK "Umweltbedingungen und -prüfungen für optische Geräte" ("Environmental requirements and test methods for optical instruments") at DIN Standards Committee Optics and Precision Mechanics.
