4. Machinery and plant certification in the USA

Besides restrictions foreseen by the local laws, the OSHA and CFR 29 for some

particular machinery types, there is no obligation to certify through a third party

the plant or machinery at the moment of installation. On the other hand to get

the certification of a laboratory is possible only through a verification procedure

and a specific standard.

In specific cases of electrical equipment of machinery for the USA, the reference

standards are represented by the NEC 2005 installation code, art 409 “industrial

machinery”, and the voluntary UL 508-A “Industrial Control Panel” standard.

For the Canadian market the references to obtain a certification are the CEC 22-2

installation code, part 1 and CSA 22-2 N°14s “Industrial Control Panel” standard.

For the industrial machinery such as woodworking machine tools, machinery for

plastics and metal, some additional requirements applied are defined in the NFPA

79 Electrical Standard for Industrial Machinery.
