| GS certification requires mandatory additional testing of PAHs |
 |
|
|
GS certification is a voluntary safety testing certification based on the German Equipment Safety Act. Groceries, sporting goods, toys, and electronic products are all eligible to apply. On November 20, 2007, the AtAV Committee passed a resolution mandating the testing of PAHs (polyphenyl aromatic compounds), which was implemented on April 1, 2008.
limit
According to regulations related to PAH, such as Articles 30 and 31 of the German New Food and Dietary Supplements Act (LFGB), the Berlin Export Discussion Conference on August 2, 2005, Article 4 of the German Equipment and Product Safety Act (GPSG), etc. Product categories have different limits.
Table 1. General material limits in consumer products
recurring
(Contact with skin for more than 30 seconds) | contingency
(Contact with skin no longer than 30 seconds) |
| Benzopyrene | 1 mg/kg | 20mg/kg |
| Total amount of 16 PAHs | 10mg/kg | 200mg/kg |
| Example | Drilling machine, electric screwdriver, treadmill, etc. | Plug, coffee compressor, handle, etc. |
Table 2. Limits for food, toys and products that may enter the mouth
Category 1
May come into contact with food
Materials that can enter the mouth | Category 2
Not classified into category 1
toy materials |
| Benzopyrene | 0.1 mg/kg | 1 mg/kg |
| Total amount of 16 PAHs | 1 mg/kg | 10mg/kg |
*If the test result is greater than the limit of Category 1 but less than the limit of Category 2, in order to determine whether it meets the standards for possible contact with food or oral mucosa, the PCA ingredients need to be tested in accordance with DIN EN 1186ff and LMBG Certification 80.30-1 Article 35 Migration test. The results are evaluated based on food law standards.
PAHs (polyphenyl aromatic compounds)
The full name of PAHs is poly-aromatic hydrocarbons, which are various types of hydrocarbons formed by two or more benzene rings bonded to each other. PAHs are a group of important organic compounds that are currently known to pollute the environment. They contaminate water, soil, air, and plants through different channels. Because of their stable chemical properties, they exist in the natural environment for a long time and are cumulative. Their relationship through the food chain is During the step-by-step transfer, the concentration of pollutants increases and the toxic effect becomes greater, so it is easy to cause pollution to the ecological environment.
| The following are materials that may be contaminated by PAHs: |
 |
| |  | Plasticizer grease in rubber and plastics |
|
| | | Soot or black dyes in rubber and plastics |
|
| | | Surface coatings and paints |
|
| | | Naphthalene/Methylnaphthalene Preservatives for transportation and storage |
|
| PAH contaminants can be found not only in rubber, but also in different plastics such as ABS, PP and paint. |
