BS ISO 9022-3:2015 pdf free.Optics and photonics一Environmental test methods
This part of ISO 9022 specifies the methods relating to the environmental tests of optical instruments including additional assemblies from other fields (e.g. mechanical, chemical, and electronic devices),under equivalent conditions, for their ability to resist the influence of mechanical stress.
The purpose of the testing is to investigate to what extent the optical, climatic, mechanical, chemical,and electrical (including electrostatic) performance characteristics of the specimen are affected by mechanical stress.

When testing optical instruments, a half-sine shock pulse shall be applied. The specimen shall be subjected to three shocks in each direction along each axis.
Unpackaged optical instruments shall not be tested unless they are especially designed, constructed,and armoured (e.g. rubber armouring) for free fall. The degrees of severity are applicable to normal transport handling. Unless otherwise prescribed in the relevant specification, the specimen shall be subjected to two falls. If another number of falls is taken, the total number of falls shall be preferably taken from the following series: 10, 20, 50.
The degrees of severity specified in Table 8 are relevant to optical instruments because the low frequencies combined with large displacement amplitudes do not stress optical instruments.BS ISO 9022-3 pdf download.
