Anotation

This specification covers preformed dense elastomeric compression gaskets and accessories for use in sealing and glazing applications. These materials are generally used to seal or serve as components of compression sealing systems between mechanically restrained surfaces in building constructions. The elastomeric materials shall be manufactured from a high-quality ozone-resistant compound that, when properly cured, will comply to the requirements specified. The cured compound shall be suitable for use where resistance to sunlight, weathering, oxidation, and permanent deformation under load are of prime importance. The preformed gaskets or shapes shall be free of porosity, surface defects, and dimensional irregularities that may affect serviceability. The specimens shall be subjected to the following test methods: hardness test, compression set test, ozone resistance test, tensile strength test, elongation test, heat aging test, tear strength test, brittleness temperature test, non-staining test, and flame propagation test.
