PAHs Testing

Global PAHs control requirements are increasingly strict. Many regulations, such as EU REACH, German GS mark certification, have set PAHs control requirements in products. CTI provides PAHs testing services for products and raw materials, helping enterprises reduce the risk of violation of regulations and enter the international market successfully.

◉ Service Background

Polycyclic aromatic hydrocarbons (PAHs) are hydrocarbons with two or more benzene rings linked together. Up to now, more than 200 PAHs compounds have been found.

PAHs are a kind of hazardous substances formed by incomplete combustion or high temperature treatment of fuels such as petroleum and coal, wood and combustible gases. They are usually found in petrochemical products, rubber, plastics, lubricants, anti-rust oil, incomplete combustion organic compounds, etc., and are a series of the important carcinogens in the environment.

Many regulations, such as EU REACH, German GS mark certification, have set PAHs control requirements in products.

Restrictions on PAHs in Annex XVII of EU REACH regulation：Rubber or plastic parts that are in direct and long-term or short-term repeated contact with human skin or mouth.

The list of restricted PAHs in the EU REACH regulation is shown in the table below:

2）The standard AfPs GS 2019:01 PAK in GS certification has been officially effective on July 1, 2020, and replaced the old standard AfPs GS 2014:01 PAK. The number of PAHs under control was adjusted from 18 to 15.

The list of restricted PAHs in the GS certification is shown in the table below:
