1、Designation:D527722Standard Test Method forPerforming Programmed Horizontal Impacts Using anInclined Impact Tester1This standard is issued under the fixed designation D5277;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of
2、last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the procedures for reproducingand comparing shock damage,such as that which may resultfrom rail swi
3、tching or pallet marshalling impacts,using anincline impact tester.It is suitable for simulating the types ofshock pulses experienced by lading in rail switching of rail carswith standard draft gear,but not for those with long travel draftgear or cushioned underframes.The test method can also beused
4、 for pallet marshalling tests.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of the
5、safety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.For specific hazards statements,see Section 6.1.4 This inter
