Anotace textu normy ASTM C509-06(2021) :
This specification covers elastomeric cellular preformed gasket and sealing materials. Elastomeric cellular materials shall be manufactured from natural rubber, synthetic rubber, rubber-like materials, or mixture of these, with added compounding ingredients. The material shall conform to the required physical properties such as: compression-deflection, compression set, heat aging, dimensional stability, ozone resistance, low-temperature brittleness, water absorption, flame propagation, and nonstaining. The two classifications of material according to ozone resistance are Type I and Type II. Test for each physical properties shall be made.

9.1?Flame Propagation:? 9.1.1?This specification has two options: 9.1.1.1?Option IFlame propagation test is required. 9.1.1.2?Option IIFlame propagation test is not required. 9.1.2?In case no option is specified, Option I will apply. 9.2?This specification has two classifications as related to ozone resistance. These are Type I and Type II, with the latter having the greater resistance to ozone. The type should be specified when making reference to this specification but in the event that the type is not specified, Type II shall apply. Note 2:?Type II is included in this specification for use
where greater ozone resistance is required.

1.1?This specification applies to those elastomeric cellular materials of a firm grade that are manufactured in preformed shapes for use as gaskets and for use as sealing materials, in the form of compression seals or gaskets, or both, for glazing other building joint applications. Note 1:?For softer cellular elastomeric materials used in
secondary sealing applications, refer to Specification D1056.
1.2?Test Method C1166, as referenced in this specification, should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. 1.3?The following precautionary caveat pertains only to the test method portion, Section 11, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations. 1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
