1.1 This test method covers the random vibration testing of filled shipping units. Such tests may be used to assess the performance of a container with its interior packing and means of closure in terms of its ruggedness and the protection that it provides the contents when subjected to random vibrational inputs. 1.2 This test method provides guidance in the development and use of vibration data in the testing of shipping containers. 1.3 Two alternative vibration control techniques are described as follows: 1.3.1 Method A Closed Loop--Automatic Equalization (5.2.1, 10.2.1) 1.3.2 Method B Open Loop--Data Storage Media (5.2.2, 10.2.2 ) Note 1--Sources of supplementary information are listed in the Reference section (1-10). 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. Specific safety hazard statements are given in Section 6.
