Foreword

This standard replaces GB/T 3772-1998 "platinum and rhodium 10 - platinum thermocouple wire", GB/T 1598-1998 "platinum and rhodium 13 - platinum thermocouple wire" and GB/T 2902-1998 "platinum and rhodium 30 - 6 platinum and rhodium thermocouple wires" This standard GB/T 3772-1998, GB/T 1598-1998, GB/T 2902-1998 compared to the standard three main changes are as follows:

--- This revision is three standards into one standard;

--- Thermal emf tolerance of the use of the relevant provisions of ASTME230-2003;

--- Unevenness of the thermal electromotive force at both ends of the sample tested by the test to continuous tests. Appendix A of this standard and Appendix B is an informative annex. The standard proposed by China Machinery Industry Federation. The standard instrument functional materials by the National Standardization Technical Committee (SAC/TC419) centralized.

1 Scope

GB/T 1598-2010 is the Chinese national standard on platinum-10%rhodium/platinem thermocomouple wires - platinum-13%rhodium/platinem thermocomouple wires - platinum-30%rhodium/platinem-6%rhodium thermocomouple wires, in the field of metrology and measurement. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 1 December 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 May 2011. Classification: ICS 17.200.20, CCS N11. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the platinum and rhodium 10 - platinum thermocouple wire, platinum and rhodium 13 - platinum thermocouple wire, platinum and rhodium 30 - 6 platinum and rhodium thermocouple wire Products, Technology Operation requirements, test methods, inspection rules, modes of supply, packaging and marking. This standard applies to the manufacture of platinum and rhodium 10 - platinum thermocouple, platinum and rhodium 13 - platinum thermocouple and platinum and rhodium 30 - 6 platinum and rhodium thermocouple alloy wire (hereinafter Said dual wire).
