TESTING

TESTING

Determining a product or material’s characteristics in a laboratory or on site.

Testing provides businesses with the confidence that products are safe, of the right quality, and conform to specifications and applicable regulations. We perform testing and analysis services in three sectors: commodities, consumer products and industrial equipment.
