What is approved packaging for dangerous goods?
Understanding ADR obligations

All dangerous goods must be packed in an approved packaging, i.e. one that has been tested for leak-tightness, strength, etc., in accordance with the requirements set out in Chapter 6 of the ADR, entitled "Requirements for the construction of packagings, intermediate bulk containers (IBCs), large packagings, tanks and bulk containers, and the tests they must undergo".
