The REACH Directive and what types of testing RC can offer to show compliance

The REACH Directive is:

Regulation (EC) No 1907/2006 of the European Parliament and of the Council of 18 December 2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), establishing a European Chemicals Agency.

This requires all manufacturers or importers of chemicals or articles containing certain specified chemicals or substances into the EU (one tonne or more per annum) to register these substances with the European Chemicals Agency (ECHA) and comply with certain limits. These are shown in a number of Annexes to the Directive.

Rubber Consultants can test a wide range of materials and products for compliance.


Polyaromatic Hydrocarbons (PAHs) in tyres

REACH has designated ISO 21461 as the standard testing method.

BSISO21461:2009, Rubber -Determination of the aromaticity of oil in vulcanised rubber compounds

The restrictions on PAHs are regarded as kept, if the vulcanised rubber compounds do not exceed the limit of 0.35% Bay protons as measured and calculated by ISO21461.

PAHs may be present in extender oil, carbon black, rubber additives, reclaimed rubber and other components of tyres.

Individual PAHs

REACH Annex XVII has placed a restriction on the use of 8 PAHs in tyres and extender oil. Tyres will not be allowed to be placed on EU market if 8 PAHs exceed certain concentration thresholds – again, these are regarded as kept if the measured bay proton level is below 0.35% as measured by ISO21461. Manufacturers of extender oils must confirm compliance with this list of 8 PAHs separately.

Substances of Very High Concern (SVHCs) are included in Article 57 of REACH Regulation, and REACH Annex XIV:

Some SVHCs could be present in tyres. Both PAHs and SVHCs might have been introduced to tyres during the manufacturing process via the addition of non-compliant raw materials.

To protect consumers and avoid possible product recall, sales ban or penalties, tyre companies need to take PAHs and SVHCs seriously in their products. Laboratory testing is the most reliable way to identify PAHs and SVHCs in products and ensure compliance.

Tyre manufacturers, importers and distributors need to know whether toxic chemicals such as PAHs and SVHCs exist in tyres to meet their REACH obligations. Tyre manufactures also need to ensure all raw materials have been registered and their uses have been covered in the registration.

Rubber Consultants can offer the following compliance testing for tyres as well as any other material or article that falls under the REACH directive:

PAH Testing according to ISO 21461 (NMR)

PAH Testing according to ZEK method (GCMS)
