JB/T 10327-2011Fire resistant busbar trunking systems (fire resistant busways) (English PDF)

JB/T 10327-2011 is the English-translated version of 耐火母线干线系统（耐火母线槽）.

JB/T 10327-2011 is a recommended Chinese machinery industry standard for fire resistant busbar trunking systems, also called fire resistant busways. It gives the terms and definitions, the product classification, the conditions of use, the technical requirements and the verification methods. Busways with rated voltages not exceeding 1000 V, 1140 V included, at a frequency of 50 Hz or 60 Hz fall within it, in residential, commercial, public, agricultural and industrial buildings, as do lighting busbar systems supplied through tap-off units and busbar systems serving communication and control systems. Components selected within a busbar system, such as circuit breakers, are outside it and follow their own standards. Among the standards it quotes are GB 4208-2008, GB 7251.1-2005, GA/T 537-2005 and JB/T 3085. It supersedes JB/T 10327-2002.
