Copper plates need to undergo California 65 certification testing. California 65 certification is a standard for testing the phthalate content and total lead content of each material on the product. The material of the copper plate may contain harmful substances such as lead and cadmium, so Need to test. Passing the California 65 certification test can ensure the safety of copper plate products and protect the health of consumers. If copper plate products fail to pass the California 65 certification test, they may not be sold or used in the U.S. market, and may even face penalties.



Copper plate California 65 testing standards:

1. Lead content: shall not exceed 0.3ppm.

2. Cadmium content: shall not exceed 40ppm.

In addition, California 65 certification also requires the detection of substances such as phthalates and bisphenol A to ensure that their contents are within safe limits.



Copper plate California 65 test items:

1. Lead content: California 65 certification has very strict requirements for lead content, which must not exceed 0.3ppm. The method of testing lead content usually uses spectral analysis or chemical analysis to accurately determine the lead content in the copper plate.

2. Cadmium content: California 65 certification also has very strict requirements for cadmium content, which must not exceed 40ppm. The method of testing cadmium content is similar to that of lead content, usually using spectral analysis or chemical analysis.

3. Phthalate content: California 65 certification also requires testing the phthalate content in copper plates to ensure that the content is within a safe range. Phthalates are common plasticizers that are harmful to human health. Methods for testing phthalate content include gas chromatography, high-performance liquid chromatography, etc.

4. Bisphenol A content: Bisphenol A is a common chemical that is harmful to human health. California 65 certification requires testing the content of bisphenol A in copper pans to ensure that the content is within a safe range. Methods for testing bisphenol A content include gas chromatography, mass spectrometry, etc.

Copper plate California 65 testing cycle

The normal test cycle is 5~7 working days
