DGR 6.0.4.0.3 is an explanatory paragraph saying that UN packagings can be used for different Packing Groups, but must be supported with a Test Certificate. The paragraph uses a package for liquids as an example. Please do not misunderstand that the explanation does not refer only to packages containing liquids but is applicable to any other UN packagings.. For instance, your Shipper wants to use a 4G/X33/… package for dangerous goods of PG III but with a gross weight of 35 kg. The package had been tested for PG I at maximum 33 kg gross weight and therefore passing the test, it was marked as 4G/X33/…. You will need to have the package tested for PG III whether it can hold 35 kg gross weight. If the shipper can prouce a Test Certificate showing 4G/Z35/… then he can use the package to ship is PG III 35 kg substance. A test must be done and a test report will be issued which must be shown to the carrier. A new paragraph has een added in 62nd Edition DGR as 6.0.7 covering “Marks on Packagings tested to more than One Design Type”. After passing the test, the package will show two lines, i.e., 3G/X33/… and 4G/Z35/….
