scope:

This Standard provides identification coding for manifolds used in hydraulic systems and for component installation features (for example, mounting surfaces or cavities) of such manifolds. It specifies identification codes to be marked on manifold blocks and correlated with product and service documentation such as circuit diagrams, assembly drawings and bills of material, for the purpose of facilitating assembly, installation, use and service of systems in which the manifolds are applied. The codes define a unique identifier traceable to associated documentation for each mounting surface or cavity. The installed component may be marked or tagged with the same identifier when such marking is necessary for clarity in assembly or service.

NOTE : The International Standard(s) corresponding to this Standard and the symbol of degree of correspondence are as follows:

ISO 16874 : 2004 Hydraulic fluid power-Identification of manifold assemblies and their components (IDT)

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ IEC Guide 21.
