ASTM C542-05(2017)

Annotation of standard text ASTM C542-05(2017) :

This specification defines the required properties of lock-strip gaskets where resistance to sunlight, weathering, flame, oxidation, permanent deformation under load, and diminution of gripping pressure are prime essentials. Gaskets shall be manufactured from an ozone-resistant compound and shall not be dependent for ozone resistance on surface protection which can be removed by abrasion, detergents, or other means. The tensile strength test and elongation test shall be performed to meet the requirements prescribed. Tear resistance test, hardness test, compression test, brittleness temperature test, ozone resistance test, heat aging effect test, flame propagation test, and lip pressure test shall be performed to meet the requirements prescribed.
