ASTM F38-00(2006) 垫片材料蠕变松驰作用的标准试验方法

These test methods are designed to compare related materials under controlled conditions and their ability to maintain a given compressive stress as a function of time. A portion of the torque loss on the bolted flange is a result of creep relaxation. Torque loss can also be caused by elongation of the bolts, distortion of the flanges, and vibration; therefore, the results obtained should be correlated with field results. These test methods may be used as a routine test when agreed upon between the consumer and the producer. Note 18212;Test Method B was developed using asbestos gasket materials and at issuance substantiating data were not available for other gasket materials. FIG. 1 Relaxometer, Test Method A1.1 These test methods provide a means of measuring the amount of creep relaxation of a gasket material at a predetermined time after a compressive stress has been applied.1.1.1 Test Method A Creep relaxation measured by means of a calibrated strain gauge on a bolt.1.1.2 Test Method B Creep relaxation measured by means of a calibrated bolt with dial indicator.1.2 The values stated in SI units are to be regarded as the standard.

ASTM D6515-00(2004) 测定橡胶轴密封件从弯曲复原的标准试验方法

Among the factors affecting shaft seal life are the ability to retain elasticity and compensate for shaft eccentricity, ability to recover from bending, and resistance to wear and the swelling effects of contact fluids. In-service testing of candidate materials is time consuming and therefore costly. Measurement of recovery from bending after exposure in fluids at elevated temperatures provides a means of quickly assessing the materialrsquo;potential and acceptability for use. Comparative recovery data may then be screened and optimum performing compounds selected for further improvement or seal fabrication. It has been found that good to excellent correlation exists between a materialrsquo;ability to recover from bending and sealing effectiveness. This method is designed to measure the recovery of different rubber compounds after aging in any liquid medium, including hydraulic oils and water. This method can also be used to test rubber compounds after aging in air. Test liquids should be chosen based on the intended end use.1.1 This test method covers a procedure to determine the recovery response of rubber after particular bending deformation, subsequent to aging in selected media at a specified temperature, and for a specified time period, thus providing a measure of the relative performance potential of compounds used in the manufacture of shaft seals.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.This standard does not purport to address all of the safety concerns, if any, associated with its use.

ASTM F37-00 垫片材料密封性的标准试验方法

1.1 These test methods provide a means of evaluating the sealing properties of sheet and solid form-in-place gasket materials at room temperature. Test Method A is restricted to liquid leakage measurements, whereas Test Method B may be used for both liquid and gas leakage measurements. 1.2 These test methods are suitable for evaluating the sealing characteristics of a gasket material under different compressive flange loads. The test method may be used as an acceptance test when the supplier and the purchaser have agreed to specific test conditions for the following parameters: test medium, internal pressure on medium, and flange load on gasket specimens. 1.3 The values stated in SI units are to be regarded as the standard. The values 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.

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.
