Phạm vi áp dụng / Scope of standard

4.1 This practice provides information on the creep of bonded metal parts subjected to combined effects of temperature, shear, and time.

1.1 This practice covers the determination of the amount of creep of metal-to-metal adhesive bonds due to the combined effects of temperature, tensile shear stress, and time.

Note 1-Since the characteristics that render a material resistant to creep under the condition of test are not yet completely known, the details of the procedure considered herein are those known to have important influences. Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature.

1.2 Test periods depend upon the reasonable life expected from the material in service. The uncertainties of extrapolation should be considered in deciding upon the length of the test.

1.3 The values stated in SI units are to be regarded as the standard. The values 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. 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.
