RoHS Directive regulates 10 chemicals in Electronic/Electrical Products

RoHS Directive initiated (effective) in 2006

Agreement among EU Member states intended to reduce unsafe chemicals in the environment. Over the years, other global agencies have signed on – Japan RoHS, US RoHS, China RoHS, etc. Highly associated with WEEE (Waste Electrical and Electronic Equipment) Directive 

RoHS, 2006

Limits certain chemicals in electronic products. Mostly perceived as a “Lead (Pb) free solder” directive, but also includes other heavy metals (Cd, Hg, Cr (Hexavalent)) and flame retardants (Bromines)).  RoHS is a self-directed, self-test directive. No third-party testing is required, all signees self-certify. RoHS exempts certain High-reliability required products in the auto and medical markets. Auto electronics are certified via QS9000/9001 standards. RoHS directive is somewhat wanting in clarity.

RoHS 2, 2011

Clarifies Regulations. Brings RoHS requirements under CE Mark, which is similar to U.L. Listing. Eliminated certain medical exemptions.

Includes orthophthalates. Affects all kinds of electrical and electronic products including adhesives, wire/cable insulation and securing materials. Key addition is orthophthalates; regulates 4 chemicals, DEHP, BBP, DBP and DIBP
