All SAE Power’sStandard Products marked with an RoHS Logo on the datasheet are in full compliance with RoHS Directive as defined below.

EU Directive 2002/95/EC Restriction of Hazardous Substances (RoHS) is a ‘Single Market’ Directive restricting certain hazardous substances to reduce the environmental impact of EEE (electrical and electronic equipment) by restricting the use of certain hazardous substances during manufacture. Certain equipment is exempt (see End Equipment definitions Legislative Requirements). Compliance to the RoHS directive is required by 1st July 2006.

All electronic equipment contains some degree of hazardous substances including some or all of the following ; lead , mercury , hexavalent chromium , cadmium and brominated compounds With the increasing proliferation of electronic equipment and its shorter lifecycles , more and more of this equipment finds its way into landfill sites. In the interests of the environment it is desirable to restrict the amount of hazardous substances that can accumulate.

The current review of the RoHS directive aims to set official guidance on the level of acceptable impurities for the banned substances. From 1 July 2006, new electrical and electronic equipment put on the market should not contain Lead, Mercury, Hexavalent Chromium, Cadmium, Polybrominated Biphenyls (PBB) or Polybrominated Diphenyl Ethers (PBDE)

Maximum Concentration Values (MCVs) were written into the Official Journal of the European Commission on 18 August 2005 allowing “A maximum concentration of 0.1% by weight in homogenous materials for lead, mercury, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) and of 0.01% by weight in homogenous materials for cadmium shall be tolerated”

Homogenous materials means ‘’a unit that can not be mechanically disjointed into different materials” The term “mechanically disjointed” means that the materials can be in principle separated by mechanical actions such as for example: unscrewing, cutting, crushing, grinding and abrasive processes. In other words Components like Resistors, capacitors, semiconductor devices, connectors, plastic housing, wire, fasteners are not considered as homogenous Materials (eg Lead frame coating, ceramic used in ceramic capacitors, plastic used in connectors and in housings, wire insulation, individual coating layers on fasteners are considered as homogenous). The maximum concentration levels of restricted substances apply to each sub part of this component .The component is not considered as ‘homogenous material’ in itself.

Equipment covered under the scope of the RoHS Directive is as follows ‘’Electrical and electronic equipment falling under the categories 1,2,3,4 ,5 ,6 ,7 and 10 set out in Annex 1A to Directive No 2002/ /EC (WEEE) and to electric light bulbs , and luminaires in households ’’ Namely;

1. Large Household appliances.
2. Small Household appliances
3. IT and telecommunications equipment.
4. Consumer equipment.
5. Lighting.
6. Electrical and electronic tools (except large scale stationary industrial tools).
7 Toys, leisure and sports equipment
10 Automatic dispensers

There are a number of exemptions to this list which are detailed in the Annex of the RoHS Directive. The Annex will also be reviewed periodically and amended from time to time. Categories 8 ( Medical Equipment ) and 9 (Monitoring and Control Equipment ) are not currently covered by the RoHS Directive but are under review.

A “Producer” will typically carry out some or all of the following activities: Manufactures and sells his own brand; Resells under his own brand; Imports or exports into the EU Self-declaration. Self Declaration is a common method used for many new EU Directives. Products placed on market would be presumed to comply with the RoHS Directive and be enforced by market surveillance. An enforcement authority may request evidence that a producer has used due diligence and taken “reasonable steps” to comply.

SAE Power has a Self Declaration policy supported declarations of it’s suppliers and audited as required. SAE has has issued a new purchasing control document for all compnents. A master Certificate of Conformance has been completed by SAE’s suppliers and reference made to this on delivery or advice notes accompanying the product. Where possible, only RoHS compliant components will be procured. Regular vendor audits will include compliance to RoHS with in house verification testing.
