According to California Proposition 65, the testing of water bottles needs to focus on harmful substances that may migrate into drinking water. The following are the core test items and standards:
I. General Mandatory Test Items (All Cup Materials)
1. Heavy Metal Extraction
- Lead (Pb):
- Food contact surface of flat cups (e.g., plates): ≤ 0.226 ppm
- Internal contact surface of hollow cups (e.g., mugs): ≤ 0.100 ppm
- Cadmium (Cd):
- Rim area: ≤ 0.050 μg/mL (Pb), ≤ 4.00 μg/mL (Cd)
2. Phthalates
- Six restricted substances: DEHP, BBP, DBP, DIDP, DnHP, DINP, etc., each ≤ 0.1% (1000 ppm)
- Test Scope: Only accessible parts (e.g., cup coating, seal)
3. Bisphenol A (BPA)
- Content in plastic/coating materials: ≤ Limit Values (Specific limits are determined by material type)
II. Additional Items by Material
| Material Type | Additional Testing Items
| Ceramic/Glass Cups | Lead and Cadmium Dissolution from Lip (Contact Area of Cup Rim)
| Metal Cups (Aluminum/Copper) | Lead Content in Welded Parts (e.g., Solder Joints on Copper Plates) ≤ 200 ppm
| Plastic/Silicone Cups | Formaldehyde Emission, Flame Retardants (Containing Bromine/Phosphorus) |
III. Key Considerations
1. Testing Area Requirements:
- Only test accessible parts (e.g., inner wall, cup rim, straw); non-contact areas do not require testing.
2. Warning Labels:
- If a cup contains listed chemicals (even if the limit is not exceeded), a warning (e.g., "⚠️ Contains lead, may cause cancer") must be placed on the product packaging.
3. Updates and Compliance:
- The California Proposition 65 list is updated annually (if new substances such as PFAS are added). It is recommended to regularly review the latest version.
IV. Simplified Testing Process
1. Sampling: Send two to three complete samples (including all accessories).
2. Laboratory Selection: Requires a CPSC-authorized laboratory (e.g., Dezewei ID: 1552).
3. Report Content:
- Product Description, Production Information (accurate to city, year, and month)
- List of Applicable Regulations (e.g., CPSIA, ASTM F963).
