ISO/TS 11366:2011

Petroleum and related products — Guidance for in-servicing of lubricating oils for steam, gas and combined-cycle turbines

Scope

ISO/TS 11366:2011 applies to mineral oils used as lubricating oils and to control fluids used to lubricate steam, gas and combined cycle turbines in service. The lubricants considered in ISO/TS 11366:2011 are those classified in ISO 6743-5 and specified in ISO 8068.
ISO/TS 11366:2011 is intended to

help power equipment operators evaluate the conditions of the oil in their equipment and maintain the oils in serviceable conditions;
help users understand how the oils deteriorate and carry out a meaningful programme of sampling and testing of oils in use.

ISO/TS 11366:2011 also gives instructions with respect to the corrective actions that are taken to maximize service life.
