Optics and photonics. Lasers and laser-related equipment. Test methods for specular reflectance and regular transmittance of optical laser components1 Scope This International Standard specifies measurement procedures for the precise determination of the specular reflectance and regular transmittance of optical laser components. The accuracy of the described test methods exceeds that of measurement procedures outlined in ISO 15368 by several orders of magnitude.

NOTE The moving mechanism is covered by ISO 22827-2

Why should you use BS EN 50342-3 - Lead-acid starter batteries

The ISO 15223 series of standards addresses symbols that can be used to convey information that is essential for the safe and proper use of medical devices

The test levels in BS EN 50470‑3 are regarded as minimum values to guarantee the proper functioning of the Static meters for active energy under normal working conditions

BS EN 61935-3 addresses both verification and qualification of home cabling
