27、n common use in the countries of the participating members. Pressure drums is intended to be designed, manufactured, and closed so that during normal conditions of transport including the effects of handling, temperature, vibration, humidity, or pressure, there will be no release of dangerous goods
28、that would endanger public safety.This part of ISO 21172 is intended to be used under a variety of national and international regulatory regimes.
