Restriction of Hazardous Substances testing is a result of the Restriction of Hazardous Substances Directive, which became effective on July 1, 2006. This directive was ratified in the European Union as an effort to protect individuals from hazardous substances. This testing has become a standard procedure for manufacturers, sellers, distributors and recyclers of electronics in the European Union. Laboratories in both Europe and the United States offer manufacturers extensive Restriction of Hazardous Substances testing services in order to ensure that their products meet the established guidelines.

Restriction of Hazardous Substances testing looks for several hazardous substances, including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers. Testing identifies instances of concentration values of these substances exceeding 0.1 percent (or in the case of cadmium, 0.01 percent). There are some additional exceptions; for example, up to 4 percent lead can be present in copper alloys, and military arms and munitions are exempt.
