scope:

This part of ISO 10438 specifies the minimum requirements for lubrication systems, oil-type shaft-sealing systems, dry gas face-type shaft-sealing systems, control-oil systems and other auxiliaries for general- or special-purpose applications. General-purpose applications are limited to lubrication systems. These systems may serve equipment such as compressors, gears, pumps, and drivers. This part of ISO 10438 is not applicable to internal combustion engines. This part of ISO 10438 is intended to be used for services in the petroleum, petrochemical and natural gas industries. This part of ISO 10438 covers the minimum requirements for oil systems intended to supply lubricating oil to machines in general-purpose applications and is intended to be used in conjunction with Part 1 of ISO 10438. Typical schemas for general-purpose oil systems are provided in Annex A.
