scope:

This specification defines the test methods and procurement procedures for a range of single component liquid compounds which polymerise upon the ' +' exclusion of oxygen and actuation by a metal surface.

When the compounds are used on metallic surfaces the prior use of activator shall not normally be required. The compounds shall respond to the use of an activator if its use is required by prevailing circumstances, eg on non-metallic surfaces.

General applications of these materials include locking and sealing threaded fasteners and assembling slip-fitted parts. The materials should not normally be used on electrical connections where the assembled connection is required to carry electrical currents, Some of the compounds are compatible with certain explosives and propellants, but the appropriate Design Authority Approval must be obtained before use in proximity to such materials.
