[QUOTE="Traineeboy, post: 519747, member: 32807"] To determine if an metal work is classed as an extraneous conductive parts then I understand that a test is to be carried out between the metal work in questions and the MET. I know as a general rule if the reading comes back as 22Kohms of higher then the part doesn’t need bonding, however some people state it’s a continuity test between metal work and MET and others are saying it’s an IR test. I could see how both could he right but would like clarity. continuity test - You are simply testing to see if there is continuity between that metal work and earth. IR Test - you are seeing if there is resistance between the metal work and earth. Any thoughts would be appreciated [/QUOTE]
