United Nations Testing

The UN Publication "Recommendations on the Transport Of Dangerous Goods Model Regulations" and its counterpart "Recommendations on the Transport Of Dangerous Goods Manual of Tests and Criteria" are the internationally recognized authority for the testing, packaging, and shipping of Dangerous Goods.

Epec follows these documents and provide our customers with safe, tested battery assemblies that can weather the rigors of transport. New battery assemblies requiring testing are certified for transport against a series of tests as applicable.
