This document applies to carbon brushes for electrical machinery. For the present, it applies only to carbon brushes for commutators and slip-rings in rotating machines.<\/p>\n
Terms and definitions are relative to the brush construction (references 100\u2019s to 500\u2019s and parts of 900\u2019s) and to the markings when operating on a rotating machine (references 600\u2019s to 800\u2019s).<\/p>\n
By extension, terms and definitions may be relevant for any kind of sliding electrical contacts for electrical machinery.<\/p>\n
