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.

America's Oldest. A History of Innovation.

Today at Epec, the customer comes first, and everything we do must be put through that filter. Whether it is developing e-commerce platforms to make it easier to work with us, or creating a NPI (new product introduction) process that helps our customers get to market faster, or the other 10 new projects we have in process, we must focus on building the new. By doing that every day, and by always making the customer our top priority, we plan on being here for another 65 years and then some.
