RoHS Directive   

ELV – (End of Life Vehicle 2000/53/EC)

Legislation aimed at the automotive Industry

Reason it was written was to reduce the effect on the environment due to the scrapping of vehicles.

It is written to cover two stages, Scrapping of existing vehicles to landfill and the restriction of substances that can be used to build new vehicles.

WEEE (Waste Electrical & Electronics Environmental 2002/96/EC)

The Waste Electrical and Electronic Equipment Directive  (WEEE) aims to minimise the impacts of electrical and electronic equipment on the environment during their life times and when they become waste.  It applies to a huge spectrum of products.  It encourages and sets criteria for the collection, treatment, recycling and recovery of waste electrical and electronic equipment.  It makes OEMs responsible for financing most of these activities. Private householders are to be able to return WEEE without charge.

RoHS  (Restriction of Harmful Substances 2002/95/EC)

The RoHS Directive will ban the placing on the EU market of new electrical and electronic equipment containing more than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants from 1 July 2006.  There are a number of exempted applications for these substances. RoHS takes its scope broadly from the WEEE Directive.  Manufacturers will need to ensure that their products - and their components - comply in order to stay on the European market.

Banned Substances applicable to TR Fastenings

Hexavalent Chrome

Also known as Chrome 6 (CR6)

Hexavalent Chrome is a chemical used in the passivation of electro plating and is added to mechanical plating to create a corrosion resistant i.e. Zinc & Clear will have hexavalent chrome in the clear passivate, dacromet has hex chrome added to the coating.

Hexavalent chrome is carcinogenetic (activates cancer within the body) and has been replaced by Trivalent chrome (also known as Chrome 3 or CR3), which is natural to the environment and the human body, therefore is safe to use and does not have a detrimental affect on the environment.

There are differences in the performance between Hexavalent & Trivalent chrome, Trivalent does not self repair as does Hexavalent chrome therefore if scratched will rust. This is overcome by applying a wax on top of the passivate. This is called thick Trivalent, not only does it self repair but will then give a greater corrosion resistance. Without the wax the process is called thin Trivalent.  There are other alternatives to this that platers may offer i.e. by adding cobalt to the plating.

Lead

Banned except for the following exemptions: Lead Allowance as an alloying element, therefore to improve machineability:

Steel containing up to 0.35% lead by weight

Copper Alloy containing up to 4% lead by weight

Aluminium containing up to 0.4% lead by weight

Methods of Communication

Is used in conjunction with some of our major Electronics Industry customers to provide regulatory declarations. http://www.bomcheck.net/

IMDS (International Material Data System). To understand and manage materials with components  IMDS now has 12 automotive companies as official members. More than 10,000 automotive supplier companies from all over the world are using the system.  TR uses this as a method of responding to customer requirements.

RoHS / WEEE Statement

Two EU Directives came into force on the 1st July 2006 – Directive 2002/95/EC on the Restriction of Hazardous Substances in electrical and electronic equipment (RoHS), and Directive 2002/96/EC on Waste of Electrical and Electronic Equipment, (WEEE)

RoHS Directive 2011/65/EU

The new directive applies to the same restricted substances as the original directive. There is a transition period for additional categories of EEE which are coming into scope of the directive. There are also changes to exclusions, exemptions procedure and conformity, including CE marking obligations.

If a compliance certificate is required, please specify at the time of ordering

We are committed to helping our customer’s select RoHS/WEEE compliant components.

Should you require any further information or assistance, please contact your TR sales contact.
