Standard Specification for Performance of Hasps and Other Attachment Devices for Padlocks or Seals

Abstract

This specification describes and grades various levels of performance to provide standard criteria upon which to select suitable hasps and other attachment devices for padlocks and seals. Specially made hasps used by the Department of Defense or other highly sensitive applications are not covered by this specification. The tests specified are laboratory tests, and although they simulate field conditions as to attacks, they do not duplicate these conditions. Hasps that have special attributes not related to security may be used. Test specimen of each size and model shall be selected at random. Four hasps shall be selected for the forcing tests. Test apparatus preparation for the tensile loading device, shock impactor, and torque test fixture are detailed. Forcing tests includes the following: (1) staple axial load test, (2) hasp staple impact test, (3) hasp staple cutting test, and (4) hasp staple torque test. The test value requirements for the forcing tests are specified for the following grades: Grade 1, Grade 2, Grade 3, Grade 4, Grade 5, and Grade 6. The impact fixture assembly including the mounting block, anvil assembly, and weight assembly; assemble torque fixture; staple axial load test fixture; and staple cutting fixture are illustrated in detail.
