ASTM F36-99 垫片材料的压缩性及回弹性的标准试验方法

1.1 This test method covers determination of the short-time compressibility and recovery at room temperature of sheet-gasket materials, form-in-place gaskets, and in certain cases, gaskets cut from sheets. It is not intended as a test for compressibility under prolonged stress application, generally referred to as "creep," or for recovery following such prolonged stress application, the inverse of which is generally referred to as "compression set." Also, it is not intended for tests at other than room temperature. A resiliency characteristic (the amount recovered expressed as a percentage of the compressed thickness) may also be calculated from the test data where desired. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Corrosion Testing of Gaskets

ASTM F363-99(2011) 衬垫腐蚀测试的标准试验方法

This test method is designed to compare all types of gaskets under simulated field operating conditions. Performance of a gasket can thus be measured prior to the start-up of chemical processes.5 The design of the test unit provides maximum range of corrosion resistance so that meaningful results are possible. This test method may be used as a routine test when agreed upon between the purchaser and the seller.1.1 This test method covers the evaluation of gaskets under corrosive conditions at varying temperature and pressure levels. The test unit may be glass lined if the flanges are sufficiently plane (industry accepted), thus providing resistance to all chemicals, except hydrofluoric acid, from cryogenic temperatures to 260176;C (500176;F) at pressures from full vacuum to the allowable pressure rating of the unit, or made of other suitable material. The test unit described (Fig. 1) has an internal design pressure rating of 1034 kPa (150 psi) at 260176;C (500176;F).1.2 The values stated in SI units are to be regarded as the standard.1.3 his standard does not purport to address all of the safety concerns, if any, associated with its use.

Standard Test Method for Corrosion Testing of Gaskets

ASTM F806-99a(2009) 垫片材料的压缩性及回弹性的标准试验方法

This test method is designed to compare related laminated composite gasket materials under controlled conditions and their short-time compressibility and recovery at room temperature. It measures compressibility with a matched pair of opposing upper and lower penetrators which provide better precision and bias than methods using an upper penetrator and a lower anvil. It is difficult to prepare undistorted test specimens from laminated composite gasket materials which will lay flat on an anvil. Also, with many composites having rigid inner layers the load on the upper penetrator is distributed over the bottom anvil area resulting in a lower than actual compressibility reading. This test method may be used as a routine test method when agreed upon between the purchaser and the producer.1.1 This test method covers determination of the short-time compressibility and recovery at room temperature of laminated composite gasket materials. 1.2 This test method is not intended as a test for compressibility under prolonged stress application, that is “creep,” or for recovery following such prolonged stress application, the inverse of which is generally referred to as “compression set.” Also, it is only intended for tests at room temperature. 1.3 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

ASTM F140-98 偏振法测定膨胀特性用的参考玻璃与金属对接密封材料的制作与试验

1.1 This practice covers the preparation and testing of reference glass-metal butt seals of two general configurations: one applicable to determining stress in the glass and the other to determining the degree of mismatch of thermal expansion (or contraction). Tests are in accordance with Method F218 (Section 2). 1.2 This practice applies to all glass and metal (or alloy) combinations normally sealed together in the production of electronic components. It should not be attempted with glass-metal combinations having widely divergent thermal expansion (or contraction) properties.

ASTM F140-98(2003) 偏振法测定膨胀特性用的参考玻璃与金属对接密封材料的制作与试验

The term “reference” as employed in this practice implies that either the glass or the metal of the reference glass-metal seal will be a “standard reference material” such as those supplied for other physical tests by the National Institute for Standards and Technology (NIST), or a secondary reference material whose sealing characteristics have been determined by seals to a standard reference material.5 Until standard reference materials for seals are established by the NIST, secondary reference materials may be agreed upon between manufacturer and purchaser. 1.1 This practice covers the preparation and testing of reference glass-metal butt seals of two general configurations: one applicable to determining stress in the glass and the other to determining the degree of mismatch of thermal expansion (or contraction). Tests are in accordance with Test Method F 218 (Section 1.1).1.2 This practice applies to all glass and metal (or alloy) combinations normally sealed together in the production of electronic components. It should not be attempted with glass-metal combinations having widely divergent thermal expansion (or contraction) properties.
