  • Harmful Substances Testing

    The environmental protection and safety laws and regulations formulated by countries or regions around the world for electronic and electrical products, parts and materials, toys and children's products and their materials, and automobile interior materials have been issued one after another. It puts forward strict requirements for toxic and harmful chemicals in products and their raw materials, and the impact of toxic and harmful substances on people is self-evident. In order to make the toxic components of the products do not exceed the standard, it is necessary to detect them. As a professional reliability third-party testing organization, T,C&A Lab can provide Harmful Substances Testing service according related standards and industry requirements. Welcome to contact our experts for consultation.

    Our testing capabilities include but are not limited to:

    • RoHS Testing
    • RoHS restricts the use of ten hazardous materials in the manufacture of various types of electronic and electrical equipment. The use of the following ten substances is restricted by this directive.

      • Lead (Pb)
      • Mercury (Hg)
      • Cadmium (Cd)
      • Hexavalent chromium (Cr6+)
      • Polybrominated biphenyls (PBB)
      • Polybrominated diphenyl ether (PBDE)
      • Bis(2-ethylhexyl) phthalate (DEHP)
      • Butyl benzyl phthalate (BBP)
      • Dibutyl phthalate (DBP)
      • Diisobutyl phthalate (DIBP)

      For ten compulsory controlled substances, the limit of cadmium (Cd) is 0.01%, and the rest are 0.1%.

    • REACH Testing
    • The REACH Directive requires that all chemicals imported and produced in Europe must go through a comprehensive set of procedures such as registration, evaluation, authorization and restriction, in order to better and more simply identify the chemical components to achieve the purpose of ensuring environmental and human safety.

      Unlike the RoHS directive, REACH covers a much wider range. In fact, it will affect products and manufacturing processes in almost all industries, from mining to textiles and garments, light industry, and electromechanical industries.

      REACH regulations stipulate that for substances of very high concern (SVHC) that meet the following two conditions, the manufacturer or importer of the articles shall notify ECHA:

      • The presence of SVHCs in articles if the total quantity used is more than one tonne per year.
      • The SVHC is present at more than 0.1% of the mass of the object.
    • PAHs Testing
    • Polycyclic aromatic hydrocarbons (PAHs) refer to a class of organic compounds with two or more benzenes. In 1976, the International Center for Cancer Research listed 94 compounds that were carcinogenic to laboratory animals, 15 of which belonged to PAHs.

      Testing range of PAHs:

      • Consumer products such as electronics, motors, etc.
      • Rubber products, plastic products, automotive plastics, rubber parts
      • Food packaging materials, toys, container materials, etc.
      • Other materials
    • Heavy Metal Testing
    • ASTM F963: Standard Consumer Safety Specification for Toy Safety.

      ASTM F963 is an American toy standard developed by the National Bureau of Standards of the US Department of Commerce. Heavy metal elements include:

      • Lead (Pb)
      • Arsenic (As)
      • Antimony (Sb)
      • Barium (Ba)
      • Cadmium (Cd)
      • Chromium (Cr)
      • Mercury (Hg)
      • Selenium (Se)

      EN71 is the standard of toy products in EU market. The elements tested include:

      • Aluminum (Al)
      • Antimony (Sb)
      • Arsenic (As)
      • Barium (Ba)
      • Boron (B)
      • Cadmium (Cd)
      • Chromium (Cr3+)
      • Chromium (Cr4+)
      • Tin (Sn)
      • Organotin
      • Cobalt (Co)
      • Copper (Cu)
      • Lead (Pb)
      • Manganese (Mn)
      • Mercury (Hg)
      • Nickel (Ni)
      • Selenium (Se)
      • Strontium (Sr)
      • Zinc (Zn)
      • Specific element migration
    • Phthalic Acid Ester Testing (PAEs)
    • Phthalate ester is a kind of widely used plasticizer, which can modify or soften plastics. It is common in plastics and paints, among which 15 kinds of phthalates are considered to be harmful substances and their use is limited.

      RoHS includes four kinds of o-benzene: DEHP, BBP, DBP, DIBP
