This study attempts to review the implications of the directive to the electronic industry as to substantial compliance and to the implications in the product quality, reliability and expense.1. Details. The Restriction on use of Hazardous Substances was initiated by the European Union in answer to the growing concerns of environmental and health issues that endanger mankind and its environment. The European Union issued directives that were enacted to a legislation in July 2007 restricting the use of hazardous substances in electrical and electronic equipments. ROHS directive complements the Waste in Electrical and Electronic Equipment (WEE) that controls the disposal of the electrical and electronic equipment (EEE).This regulation is directed to manufacturers or assemblers of electrical or electric equipment in the UK, importers of electrical or electronic equipment from outside Europe, and those who re-badge electronic products as their own. An exemption from this directive is those individuals who make purchases from abroad, and retailers who purchase their products from within the UK. (RoHS home)RoHS has confined the restricted hazardous elements to the use of lead, mercury, hexavalent chromium, cadmium, and a large range of flame retardants such as polybrominated biphenyls and polybrominated diphenyl ethers. RoHS has exempted the use of hazardous elements for a certain number of products wherein substitutes do not exist and have allowed certain permissible levels of these substances to be used.In this directive, manufacturers are obliged to conform to the policy that their products placed in the market must be free from the hazardous elements above the prescribed level. Documentation to attest to this compliance must also be held for each product and must be submitted to the DOE and must be maintained for 4 years even if the product is out on the market shelves.
