1 Scope
This part of GB/T 4857 specifies shipping containers in terms of random vibration test apparatus, test procedure and test report, etc.
This part is applicable to assessing the protection that a shipping container provides its contents when subjected to random vibration inputs. Such tests may be used as an individual test or as part of a test series.
