BS 7608+A1 covers:

BS EN 17199-1 specifies the environmental conditions

NOTE 3 This document does not apply to independent high-voltage power supply installations for which separate IEC standards exist

ISO 8504‑3 is applicable both to new steelwork and to steel surfaces that have been coated previously and those that show areas of a breakdown requiring maintenance painting

Optical fibres - Attenuation measurement methods Ingestion-build-209418 BS 7608+A1 covers:What is this standard about? This part of IEC 60793 establishes uniform requirements for measuring the attenuation of optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. Four methods are described for measuring attenuation, one being that for modelling spectral attenuation: method A: cut back; method B: insertion loss; method C: backscattering; method D: modelling spectral attenuation. Methods A to C apply
