Scope

GB/T 24946-2010 is the English-translated version of 船用数字液压缸.

GB/T 24946-2010 covers the marine digital hydraulic cylinder, which it shortens to the "digital cylinder".

Clause 1 states that it specifies the product classification, requirements, test methods, inspection rules and signs, packaging, transportation and storage of the digital cylinder, and that it applies to the design, production and acceptance of such cylinders; the page records no exclusion.

As far as the draft reaches, the body runs Scope, Normative references and Terms and Definitions, so the requirements, test methods, inspection rules and packaging announced in clause 1 are not shown.

Clause 3 defines the digital cylinder as a hydraulic cylinder whose position, speed and direction are controlled by electrical pulse signals. Clause 2 cites twenty documents, among them GB/T 699-1999, GB/T 2879, GB/T 3452.1, GB/T 3783, GB/T 7935, GB/T 8163-2008, GB/T 14039-2002, CB/T 3004, JB/T 4730.3-2005 and JB/T 7858.

The standard was proposed by China State Shipbuilding Corporation and administered by the National Marine Machinery Standardization Technical Committee, and the first drafter named is the China Shipbuilding Technology and Economy Research Institute. It was issued on 2010-08-09 and has applied since 2010-12-01.
