Toxic and Hazardous Substance Testing and Certification Services

Toxic and harmful substances refer to substances that humans come into contact with under production conditions or in daily life, which can cause diseases or decline their health status. By detecting and managing toxic and harmful substances, we ensure that the purchased raw materials and processed products meet the requirements of non-toxic or low toxicity environmental protection and comply with environmental laws and regulations in various countries. This enables our products to enter domestic and international markets and meet customer requirements and the trend of environmental development.

Key testing contents for toxic and harmful substances:

RoHS/REACH/SVHC/PoHS/WEEE/detection, antioxidant detection, flame retardant detection, mold inhibitor detection, UV absorber detection, phthalate detection, polycyclic aromatic hydrocarbons (PAHs) detection, perfluorooctane sulfonate (PFOS) detection, asbestos detection, perfluorooctanoic acid and its salts (PFOA) detection, toy 19 heavy metal detection, VOC detection, azo detection, COD detection, etc.

2. REACH regulation (SVHC testing for substances of high concern under REACH)

(1) See: List of Candidate Substances for SVHC from Batch 1 to Batch 15;

(2) Testing field: products exported to the European Union, including electronic and electrical products, toys, textiles, furniture, automobiles, and components.

3. Polycyclic aromatic hydrocarbons (PAHs)

(1) Testing items: phenanthrene, anthracene, benzo (a) anthracene, benzo (b) fluoranthene, benzo (j) fluoranthene, benzo (k) fluoranthene, benzo (ghi) perylene (dianaphthalene), benzo (a) pyrene, benzo (b) pyrene, pyrene, dibenzo (a, n) anthracene, fluoranthene, fluorene, indenzene (1,2,3-cd) pyrene, naphthalene, phenanthrene, pyrene;

(3) Testing fields: electronic and electrical products, rubber and plastic products, paint and coating products, packaging materials, toys, container materials, leather and textile products, wooden products, etc.

4. VOC (volatile organic compounds)

VOC stands for volatile organic compounds, which have a significant impact on human health. When the concentration of VOCs in the living room reaches a certain level, people may experience headaches, nausea, vomiting, fatigue, etc. in a short period of time. In severe cases, convulsions, coma, and damage to the liver, kidneys, brain, and nervous system can occur, leading to serious consequences such as memory loss.

(1) Types (including but not limited to the following): cyclohexanone, isophorone, methanol, ethanol, phenol, ethyl acetate, benzene, n-butanol, methyl isobutyl ketone, n-butyl acetate, xylene (ortho, meta, para), toluene, styrene, 1,2-dichlorobenzene, acetophenone, methyl ethyl ketone, isopropanol, dichloromethane, trichloroethylene, ethylbenzene, n-hexane, 2-methoxyethyl acetate

(2) VOC testing scope: automotive industry, textile industry, toy industry, tobacco industry, furniture decoration materials, electronic and electrical industry, printing industry, etc.

5. Ortho benzene (6P, 16P, 22P) plasticizers

6P Types: Diisononyl Phthalate (DINP), Di-n-octyl Phthalate (DNOP), Diisodecyl Phthalate (DIDP), Bis - (2-ethylhexyl) Phthalate (DEHP), Dibutyl Phthalate (DBP), Phenylbutyl Phthalate (BBP)
