ISO 10438-3:2007

Overview

ISO 10438-3:2007 is an international standard for the petroleum, petrochemical and natural gas industries that specifies requirements for general-purpose oil systems. Used together with ISO 10438-1, this part covers oil systems that supply lubrication oil (but not seal oil) and that serve rotating and driven equipment such as compressors, gears, pumps and drivers. The publication includes data sheets in SI and USC units and is intended for design, specification and procurement of auxiliaries for oil systems.

Key topics

Key technical topics and requirements addressed (as presented in ISO 10438-3 and the ISO 10438 series) include:

• Scope and system definitions - what constitutes a general-purpose oil system versus other oil/ seal systems.
• Functional requirements for lubrication supply to compressors, gears, pumps and drivers.
• Components and auxiliaries - typical items such as reservoirs, filters, pumps, heat exchangers, breathers and instrumentation.
• Performance and reliability expectations, including considerations for continuous operation in process plants.
• Data sheets and documentation - standardized data templates (available in SI and USC) to support specification and procurement.
• Installation and delivery instructions and guidance for electronic file handling included with the publication.

(ISO 10438-3 focuses on requirements and data presentation; it is used in conjunction with ISO 10438-1 for broader system principles and may be complemented by other industry standards.)

Applications

ISO 10438-3 is directly applicable to:

• Engineers and designers specifying lubrication systems for rotating equipment in oil, gas and petrochemical plants.
• Equipment manufacturers (OEMs) preparing oil system packages for compressors, gearboxes, pumps and drivers.
• Maintenance and reliability teams developing preventive maintenance, oil monitoring and spare-parts strategies.
• Procurement and compliance specialists who need standardized data sheets and technical requirements for tenders and contracts.

Using ISO 10438-3 helps ensure consistent oil system specification, interoperability of components, and clearer technical communication between operators, OEMs and suppliers.

Related standards

• ISO 10438-1 - referenced companion providing general principles for lubrication, shaft‑sealing and control‑oil systems.
• Other parts of the ISO 10438 series (consult ISO for the complete set and updates).
