scope:

This part of ISO 10438 specifies requirements for lubrication systems, oil-type shaft-sealing systems, dry-gas face-type shaft-sealing systems, and control-oil systems for general- or special-purpose applications. Generalpurpose applications are limited to lubrication systems. These systems may serve equipment such as compressors, gears, pumps, and drivers. This part of ISO 10438 does not apply to internal combustion engines. This part of ISO 10438 is intended to be used for services in the petroleum, petrochemical and natural gas industries as well as other industries by agreement. This part of ISO 10438 covers the minimum requirements for support systems for self-acting gas seals (dry gas seals) as described in ISO 10439 and is intended to be used in conjunction with ISO 10438-1.
