1 Scope

1.1 This international standard covers the minimum requirements for lubrication systems, oil-type shaft-sealing systems, dry gas face-type shaft-sealing systems, and control-oil systems for general or special purpose applications. General purpose applications are limited to lubrication systems. These systems may serve equipment such as compressors, gears, pumps, and drivers. This standard does not apply to internal combustion engines.

This international standard is intended to be used for services in the petroleum, chemical, and gas industries as well as other industries by agreement. This standard is separated into four distinct chapters. Chapters 2, 3, and 4 are to be used separately in conjunction with Chapter 1.

Note: A bullet (•) at the beginning of a paragraph indicates that either a decision is required or further information is to be provided by the purchaser. This information should be indicated on the data sheets (see Appendix D of Chapter 1, B of Chapters 2 and 3, and C of Chapter 4); otherwise, it should be stated in the quotation request or in the order.

1.2 When the purchaser, on the purchase order or on the data sheets incorporated in the purchase order, specifies that oil or gas systems shall be supplied in accordance with this international standard, this standard shall take precedence over any other section of any other standard which covers the same subject.
