Abstract
This specification sets forth the requirements for duplex, types E, J, K, N and T thermocouple wire, insulated with E-glass, S-glass, amorphous silica fiber or polycrystalline fiber. This specification presents the requirements for impregnated and non-impregnated fiber insulated thermocouple wire for normally accepted industrial use. The material shall be classified as follows: Class A-Duplex; Class B-Duplex; Class C-Duplex; Class D-Duplex; Class E-Duplex; and Class F-Duplex. Thermoelements shall be solid thermocouple grade materials with a smooth, bright finish and shall be fully annealed prior to insulating. Individual thermoelements shall be covered with a braid, or double wrap (one wrap in each direction) of glass fibers, a braid of glass fibers, or braid of fibers.
Scope
1.1 This specification sets forth the requirements for duplex, types E, J, K, N and T thermocouple wire, insulated with E-glass, S-glass, amorphous silica fiber or polycrystalline fiber.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
