1 Scope

GB/T 10067.43-2014 is the Chinese national standard on basic specifications for electroheat installations-part 43: forced convection pit resistance furnaces, in the field of manufacturing engineering. 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 6 May 2014 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 22 January 2015. Classification: ICS 25.180.10, CCS K61. 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.

GB/T 10067 provisions of this part of the common technical requirements for all types of indirect resistance furnace products, test methods, inspection rules, marks, Packaging, transportation, storage, and ordering and delivery and so on. This section applies to the natural atmosphere and controlled atmosphere, the rated temperature in the range of 100 °C ~ 950 °C various types of experiments and industrial Forced convection pit Furnace. Tempering, annealing and normalizing, carburizing steel parts as well as the main heating and heat treatment of metal parts, seepage Nitrogen, carbonitriding, blue and so on. This section also applies to similar forced convection Pit resistance furnace, the different parts can be otherwise. This section does not apply to household and similar electric appliances.
