ASTM D5277-92(1997)
(Test Method)Standard Test Method for Performing Programmed Horizontal Impacts Using an Inclined Impact Tester
Standard Test Method for Performing Programmed Horizontal Impacts Using an Inclined Impact Tester
SCOPE
1.1 This test method covers the procedures for reproducing and comparing shock damage, such as that which may result from rail switching or pallet marshalling impacts, using an incline impact tester. It is suitable for simulating the types of shock pulses experienced by lading in rail switching of rail cars with standard draft gear, but not for those with long travel draft gear or cushioned underframes. The test method can also be used for pallet marshalling tests.
1.2 The values stated in inch-pound 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 problems, 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. For specific hazards statements, see Section 6.
