This British Standard specifies requirements for the dimensions, electrical and mechanical properties of metallic resistance materials in the form of wire, strip, tape and sheet. It also provides a classification of these materialsbased on the typical temperature coefficient of resistance and resistivity, then subdivided into alloys. Codes are assigned to each known alloy within the class. Other alloys, not specifically listed, may also be classified and coded. A grading of materials, based on tolerances on resistance, is also introduced. Requirements for product marking, documentation and packaging are also specified. In addition to the definitive requirements, this standard also requires the items detailed in 1.4 to be documented. For compliance with this standard, both the definitive requirements and the
documented items have to be satisfied. Material conditions, limits of uncertainty, details of
the sizes of wire in general use and conversion factors to foot-pound units are given in Annex A
to Annex D and recommendations are also made relating to health and safety (Annex E).
This standard does not specify requirements for wire and strip supplied in cut and straightened
lengths but recommendations on tolerances are given in Annex F.
