1 Scope

GB/T 14093.7-2009 is the Chinese national standard on environmental technology requirements of machinery products for mine environments, in the field of testing. 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 2009 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 November 2009. Classification: ICS 19.020, CCS A21. 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 section provides mining machinery Industrial Products (hereinafter referred to as the product) protection types and environmental conditions, technical requirements, test Test methods, inspection rules. This section applies to the next GB/T 14092.6 specified environmental conditions general purpose machinery used in industrial products. Product categories include. Mining machinery, lifting machinery, processing machinery, transport machinery, drilling machines, mining electrical equipment.
