1、 Basic Instructions for California 65 Test of Wired Earphones
Wired headphones belong to the category of electronic devices regulated by California Proposition 65, which requires the detection of harmful chemicals on touchable parts to ensure compliance with the California market requirements. This report is one of the essential compliance documents for products to enter the California market or enter the Amazon US site smoothly.
2、 Application process
1. Preliminary evaluation and inquiry
Contact a third-party testing agency with CNAS/CMA qualifications and recognized by the California authorities, such as Dezewei Testing CNAS registration number: L8083, to provide product details for wired headphones and determine a matching testing plan.
2. Prepare materials and samples for inspection
1. Sample: Provide 2-3 complete sets of wired headphone samples, covering all accessible parts such as headphone casing, wires, plugs, etc. Non removable packaged chips that comply with RoHS standards may apply for partial exemption from testing.
2. Materials: Product user manual, Bill of Materials (BOM), testing application form provided by the testing agency.
3. Laboratory testing
The laboratory will conduct corresponding project tests on accessible components:
Determination of Heavy Metal Content by ICP-MS and Atomic Absorption Spectroscopy
Detection of Phthalates by Gas Chromatography Mass Spectrometry (GC-MS)
4. Report acquisition and confirmation
After the testing is completed, a draft report will be issued for you to confirm the details. Once there are no errors, you can obtain the official testing report. The institution will provide both paper and electronic versions of the report simultaneously.
5. Compliance closure
If harmful substances are detected to exceed the standard, warning signs that comply with California 65 regulations need to be posted on the product or packaging, such as "Warning: This product contains the well-known substance lead in California, which has teratogenic and reproductive toxicity hazards".
