EN 1514-1, Type IBC, PN 40, DIN 28091-2 / 3.8, 1.5 mm P-T diagrams indicate the maximum permissible combination of internal pressure and service temperature which can be simultaneously applied for a given gasket according its material type, thickness, size and tightness class. Given the wide variety of gasket applications and service conditions, these values should only be regarded as guidance for the proper gasket assembly. In general, thinner gaskets exhibit better P-T properties. J G eneral suitability - Under common installation practices and chemical compatibility. Limited suitability -...
