4.1 This test method evaluates strip tensile properties of reinforced geomembranes for the purposes of quality control, quality assurance, and research. In order to evaluate the full contribution of the reinforcement, testing is performed parallel to the directions of reinforcement. This test method is an index test and is not intended for design purposes.1.1 This test method is used to measure the strip tensile properties of reinforced geomembranes.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.3 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 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.

ASTM C542-05(2017) Standard Specification for Lock-Strip Gaskets Active 发布日期 :  1970-01-01 实施日期 : 

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.1.1 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.NOTE 1: The requirement of flame propagation may be waived by the architect or professional engineer when doing so does not conflict with local codes or ordinances.1.2 This specification applies only to the “locking” compression type of gasket, sometimes referred to as the “zipper” type.NOTE 2: Structural integrity and weather-tightness of the wall requires the sound design and installation of the entire system of which the gasket is only one component.1.3 The values stated in SI units are to be regarded as the standard.1.4 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.1.5 The following precautionary caveat pertains only to the test method portion, Section 7, of this specification: This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1.6 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.1.7 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.

This specification covers the material requirements for preformed elastomeric strip seals and the corresponding steel locking edge rail used in expansion joint sealing. The scope of this specification is limited to preformed non-reinforced strip seals that mechanically lock into structural steel locking lugs. The sealing element can consist of a single layer strip or have multiple webs depending on individual project requirements. When used on highway bridges, limits on maximum joint opening and minimum steel thicknesses need to be addressed. The adhesive-lubricant used to install the preformed seal into the steel locking edge rail shall be a one part moisture curing polyurethane compound. The elastomeric seals shall conform to the physical properties prescribed for (1) tensile strength, (2) elongation at break, (3) hardness, (4) oven aging, (5) oil swell, (6) ozone resistance, (7) low temperature stiffening, and (8) compression set. Requirements for preformed elastomeric seal dimensions, sampling, and test methods to determine compliance with the specified physical properties are given.1.1 This specification covers the material requirements for preformed elastomeric strip seals and the corresponding steel locking edge rail used in expansion joint sealing. The scope of this specification is limited to preformed non-reinforced strip seals that mechanically lock into structural steel locking lugs. The sealing element can consist of a single layer strip or have multiple webs depending on individual project requirements. The structural steel locking edge rail shall be anchored into the structure in accordance with the purchaser's specific details. While the scope of this specification is limited to the materials used in fabrication of strip sealing systems, it is recommended that a practical means of testing the watertightness aspects of the individual systems either in the field or at a testing laboratory be developed. When used on highway bridges, limits on maximum joint opening and minimum steel thicknesses need to be addressed.1.2 The values stated in the inch-pound system shall be considered as standard.1.3 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.
