BS EN 61439-2 defines the specific requirements of power switchgear and controlgear assemblies

Why should you use BS EN 15585-Determination of the percentage of mitadine grains and vitreous grains in durum wheat

which means it provides for classification using two systems – the first based on the chemical composition of all weld metal (paragraphs and tables carry the suffix letter A)

Steel. Determination of the thickness of surface-hardened layers Ingestion-build-93833 BS EN 61439-2 defines the1 Scope This document specifies a method of measuring the case hardening depth, surface hardening depth, nitriding hardness depth and total thickness of surface hardening depth obtained, e. g. thermal (flame and induction hardening, electron beam hardening, laser beam hardening, etc.) or thermochemical (carbonitriding, carburizing and hardening, hardening and nitriding, etc.) treatment. NOTE Surface hardened layer can be produced by mechanical method
