United Nations Recommendations are the most significant of all conventions.
Recommendations were effectively split into two parts: the Model Regulations, which form a suggested drafting for laws and regulations on the transport of dangerous goods; and the Manual of Tests and Criteria, which contains technical information about methods of testing products to ascertain their hazards. Forms a basis for uniform national and international regulations. Take into account land, sea & air transport and form a basis.
