Adhesives need to undergo California 65 testing. The testing scope of California 65 testing covers many types of products, including paints, coatings, adhesives, sealants, etc. in building materials.
The proposal restricts a variety of harmful chemicals in adhesives, mainly including but not limited to the following:
1. Lead (Pb): The lead content in specific products shall not exceed the limit of 0.02% (200ppm). Lead testing is necessary for adhesives that may be used in items such as children's toys and furniture.
2. Cadmium (Cd): California Proposition 65 also sets limits on cadmium, with the general requirement being less than 800 ppm. Cadmium testing is also important if the adhesive may be used in food contact or in items that may be touched by children.
3. Phthalates: California Proposition 65 requires that the content of phthalates such as DEHP, BBP, DBP, DIDP and DnHP in specific products does not exceed 0.1% (1,000ppm). Phthalate testing is necessary if the adhesive may be used in plastics or items that may come into contact with skin.
In addition, depending on the specific use and nature of the adhesive, testing may be required for other hazardous chemicals listed under California Proposition 65.
Implementation process
1. Application and submission: The enterprise submits an application to the certification agency and provides detailed information about the adhesive product, including product instructions, parts list, test application form, etc.
2. Sample preparation: The enterprise shall prepare a sufficient number of adhesive samples for testing in accordance with the requirements of the certification body.
3. Sample testing: The certification agency will send the samples to the designated laboratory for testing. The testing content includes chemical composition analysis, content testing, etc. to verify whether the adhesive contains harmful chemicals that exceed the California Proposition 65 limit.
4. Report and certification: After the test is completed, the laboratory will issue a test report to confirm whether the adhesive product meets the requirements of California Proposition 65. If the product meets the standards, the company will obtain the corresponding certification certificate; if the product does not meet the standards, the company needs to improve the product and re-test and certify it.
It should be noted that the list of hazardous chemicals listed in California Proposition 65 is regularly updated, so manufacturers need to continue to pay attention to product compliance to ensure that products always meet the latest safety standards. At the same time, companies also need to paste corresponding warning labels on their products to inform consumers of possible risks in the products.
