ISO 10438-1:2003 specifies general requirements for lubrication, shaft-sealing and control-oil systems and auxiliaries for use in the petroleum, petrochemical and natural gas industries. It is intended to be used in conjunction with ISO 10438-2, ISO 10438-3 or ISO 10438-4, as appropriate. ISO 10438 in its entirety specifies requirements for lubrication systems, oil-type shaft-sealing systems, self-acting gas seal systems, control-oil systems and other auxiliaries for general- or special-purpose applications. These systems can serve equipment such as compressors, gears, pumps and drivers.
None of the parts of ISO 10438 is applicable to internal combustion engines.
