1 Scope

GB/T 14093.4-2009 is the Chinese national standard on environmental technology requirements of machinery products for the industry - corrosion 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 corrosion environment industrial machinery product protection type and environmental conditions, technical requirements, test methods, inspection regulations Then, signs, packaging, transportation and storage. This section applies to general purpose machinery industrial products GB/T 14092.5 specified environmental conditions of use. Product categories include Internal combustion engines, construction machinery, heavy machinery, material handling equipment, oil and general machinery, electrical products, instruments, machine tools, parts and general And so on. This section does not apply to the presence of explosive material under special environmental conditions and marine, ships, mines, nuclear radiation used in a production environment.
