Lubricants, industrial oils and related products (class L) - Family T (Turbines) - Specifications for lubricating oils for turbines

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.

Lubricants, industrial oils and related products (class L) - Family T (Turbines) - Specification for lubricating oils for turbines

ISO 8068:2006 specifies the minimum requirements for turbine lubricants, as delivered. It specifies the requirements for a wide variety of turbines for power generation, including steam turbines, gas turbines, combined-cycle turbines with a common lubrication system and hydraulic (water driven) turbines. This International Standard does not specify the requirements for wind turbines, which are dealt with in ISO 12925-1. Whilst power generation is the primary application for turbines, steam and gas turbines can also be used to drive rotating equipment, such as pumps and compressors. The lubrication systems of these driven loads can be common to that of the turbine. Turbine installations incorporate complex auxiliary systems requiring lubrication, including hydraulic systems, gearboxes and couplings. Depending upon the design and configuration of the turbine and driven equipment, turbine lubricants can also be used in these auxiliary systems. ISO 8068:2006 should be read in conjunction with ISO 6743-5, the classification of different turbine lubricant types. The lubricants considered in ISO 8068:2006 are mineral oils, synthetic lubricants (ester and polyalphaolefin types intended for high-temperature gas turbines), synthetic lubricants (ester and polyalphaolefin types, environmentally acceptable for use in hydraulic turbines) and fire-resistant phosphate-ester type lubricants.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
