Appliance Wiring Material Testing and Certification

Our comprehensive certification program for appliance wiring material (AWM) enables you to objectively and credibly demonstrate compliance, while enabling thousands of original equipment manufacturers (OEMs) to find and source your products.

We offer a broad and comprehensive certification program for AWM. We can meet your testing and certification needs for new constructions (styles) of appliance wiring material intended for use in innovative applications and products. Our unique and constantly evolving library of AWM styles has become the industry standard for defining and sourcing these types of products. As a result, thousands of end-product manufacturers base their sourcing specifications on individual AWM styles to comply with standards and enable multiple vendor supply policies.

We test AWM to ANSI/UL 758, the Standard for Safety for Appliance Wiring Material. The types of tests performed depend on the construction and anticipated use of the product.
