--- GB/T 12929-1991. Marine high pressure piston air compressor

1 Scope

GB/T 12929-2008 is the Chinese national standard on marine reciprocating air compressor for high pressure, in the field of shipbuilding and marine structures. 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 3 March 2008 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 September 2008. Classification: ICS 47.020.30, CCS U47. 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 Marine high pressure piston air compressor (hereinafter referred to as compressor) classification, requirements, test methods, inspection rules and Signs, packaging, transport and storage. This standard applies to electric motor or diesel engine driven rated exhaust pressure range from 15MPa ~ 40MPa high-pressure piston marine air Compressor product design, production, testing and acceptance.
