PAHs Testing (Food and Textile)

Views :

Update time : 2025-04-24

On July 1, 2015, the new standard for polycyclic aromatic hydrocarbons (PAHs) control in GS-certified products, AfPS GS 2014:01 PAK, officially took effect, while the previous standard ZEK 01.4-08 expired on June 30. Products that require gs certification, such as electronics, toys, food packaging materials, plastic products, rubber products, and machinery, must comply with the new PAHs testing requirements.

PAHs (Polycyclic Aromatic Hydrocarbons)

PAHs (Polycyclic Aromatic Hydrocarbons) are chemical compounds made up of two to seven benzene rings arranged in linear, angular, or cluster structures. These compounds are mainly produced due to incomplete combustion of carbon-containing substances or during the use of petrochemical fuels. Some PAHs are highly carcinogenic and may also pose risks such as teratogenicity (ability to cause birth defects) and mutagenicity (ability to cause genetic mutations). There are over 100 known types of PAHs, with 18 common ones listed in the German standard.
