scope:

This International Standard provides requirements, recommendations and methods for the manufacture, testing and selection of thread compounds for use on ISO/API thread forms and proprietary casing, tubing, line pipe, and drill stem elements. The tests outlined within this International Standard are used to evaluate the critical performance properties, and physical and chemical characteristics of thread compounds under laboratory conditions.
These test methods are primarily intended for thread compounds formulated with a lubricating base grease. It is recognized that there may be materials used for the lubrication and/or sealing of threaded connections and drill stem elements for which these test methods are not applicable.
Whether a thread compound meets local or global environmental legislation is outside the scope of this International Standard. However, it is the responsibility of the end user to be aware of the environmental requirements of the operating area and to select, use and dispose of the thread compounds and related waste materials accordingly.
