Whether you work with hydro, wind, thermal, or alternative power generation; power generators; low voltage or high voltage distribution; power distribution racks or cables; smart grid or ensuring workplace safety, the power industry has a strong focus on standardization and interoperability.
This document specifies the minimum requirements for lubricants for turbines, as delivered. It is intended to be used in conjunction with ISO 6743-5. This document specifies the requirements for a wide variety of lubricants for the lubrication of most types of turbines for power generation, including steam turbines, gas turbines, single shaft combined cycle turbines with common lubrication system and hydraulic turbines. This document does not specify the requirements for lubricants for wind turbines, which are covered in ISO 12925-1. The following lubricants are considered: — mineral oils, of either API groups I, II, II+, III, including group III from GTL (gas to liquid) process, and III+. Some API groups II and III are suitable for high temperature gas turbines; — synthetic lubricants, esters (API group V) and polyalphaolefins (API group IV), intended for high temperature gas turbines; — synthetic lubricants, esters (API group V) and polyalphaolefins (API group IV), environmentally acceptable for use in hydraulic turbines; — fire resistant phosphate-ester type lubricants.
This Standard includes required and recommended practices concerned primarily with the prevention of water damage to steam turbines used for fossil-fuelfired electric power generation.
This Standard covers steam systems that are defined as a system containing steam generator(s) or other steam source(s), a steam distribution network and end-use equipment. Cogeneration and power generation components may also be elements of the system (gas turbines, backpressure steam turbines, condensing steam turbines). If steam condensate is collected and returned, the condensate return subsystem is a part of the steam system. This Standard sets the requirements for conducting and reporting the results of a steam system energy assessment (hereafter referenced as an assessment) that considers the entire system, from energy inputs to the work performed as the result of these inputs. An assessment meeting this standard need not address each individual system component or specific system within an industrial facility with equal weight; however, it shall be sufficiently comprehensive to identify the major opportunities for improving the overall energy performance of the steam system. This Standard is designed to be applied primarily at industrial facilities, but most of the specified procedures can be used in other facilities such as those in the institutional and commercial sectors. Use of this Standard and accompanying Guidance Document should increase the quantity and quality of energy assessments performed, with significant potential savings in implemented energy costs.
1.1 This practice covers the requirements for the effective monitoring of mineral turbine oils in service in steam and gas turbines, as individual or combined cycle turbines, used for power generation. This practice includes sampling and testing schedules to validate the condition of the lubricant through its life cycle and by ensuring required improvements to bring the present condition of the lubricant within the acceptable targets. This practice is not intended for condition monitoring of lubricants for auxiliary equipment; it is recommended that the appropriate practice be consulted (see Practice D6224 ). 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
