Scope
NB/T 32003-2012 is the English-translated version of 太阳能热利用自限温电热带.
NB/T 32003-2012 is a recommended energy industry standard of China for the self-regulating heating cables used in solar thermal installations.
It gives the terms and definitions for these cables, the structure of the product, its marking and classification, the technical requirements, the test methods, the inspection rules and the provisions on marking, packaging, transport and storage.
The cables it covers are made from a conductive polymer composite with a positive temperature coefficient of resistivity, and serve to heat or to trace solar thermal equipment at a suitable working voltage with a limited temperature.
Among the documents it quotes are GB/T 2951.11-2008, GB/T 2951.12-2008, GB/T 3048.8-2007, GB/T 3048.9-2007, GB/T 19835-2005, GB/T 20841-2007 and IEEE 515. Issued on 23 August 2012, it has applied since 1 December 2012.
