1 Scope

GB/T 10067.414-2018 is the Chinese national standard on basic specification for electroheating and electromagnetic processing installations - part 414: industrial gem furnace, 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 7 June 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 January 2019. 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.

This part of GB/T 10067 specifies the product classification, technical requirements, test methods, inspection rules, signs, and packaging for industrial gemstone furnaces. Transportation and storage, ordering and delivery. This section applies to high vacuum or under different protective atmospheres under positive pressure conditions using different growth methods (such as pulling method, bubble method, guided mode method, heat Exchange method, temperature gradient method, enthalpy drop method, etc.) Industrial gemstone furnaces that grow gem crystals, and other industrial gemstone furnaces can also be used as reference.
