Glass plates exported to Canada do indeed require SOR/2016-175 testing. This regulation focuses on the risk of lead and cadmium migration in glazed glass products and is a core document for product compliance in the market, especially crucial for plates with colored glazes or decorations.
I. Standardized 7-Step Process for Obtaining a Testing Report
1. Preliminary Preparation Stage (2 Core Actions)
- Technical Document Review
- Product Information: Model and specifications, material description (glass type/glaze composition), surface treatment process (e.g., spray glazing, decals)
- Design Documents: CAD drawings (glaze coverage area must be marked), instruction manual (food contact scenario must be clearly defined)
- Sample Preparation Specifications
- Quantity: 3 complete sets of samples (including packaging; if color boxes are included, they must also be provided)
- Condition: Clean and stain-free surface; avoid used products (pre-treatment cleaning by the laboratory is required before testing)
2. Testing Institution Selection Criteria (3 Mandatory Requirements)
- Certification: Must possess ISO 17025 laboratory accreditation (CNAS/CMA mark, Dezeway Testing CNAS registration number: L8083), and be listed in the Health Canada accredited laboratory directory.
- Experience Requirements: ≥50 SOR/2016-175 testing cases for glassware within the past 2 years (successful report templates can be requested).
- Service Scope: Must support reports in both Chinese and English (English reports are for Canadian customs clearance, Chinese reports are for domestic archiving).
II. Core Testing Items and Methods (Specific to Glassware)
1. Mandatory Testing Items (3 compulsory items)
| Testing Item | Test Method | Limit Requirements
| Lead Migration | ISO 6486-1:2012 (Immersion in 4% acetic acid for 24 hours) | ≤0.1 mg/L (Flatware, depth ≤25mm)
| Cadmium Migration | Same as above | ≤0.01 mg/L (All food contact surfaces)
| Sensory Testing | Visual (no cracks/bubbles) + Olfactory (no odor) | Must not cause color/odor migration to food.
2. Conditional Testing (Selected based on product characteristics)
- Thermal Stability Test: If labeled "Microwave Safe," a 200℃±5℃ thermal shock test is required (5 cycles of rapid cooling and heating without cracking).
- Coating Adhesion: The glaze decorative area must pass a cross-cut adhesion test (ISO 2409), with an adhesion grade ≥2.
III. Full Process Cycle and Key Milestones
| Stage | Precautions
| Document Review | If the glaze composition is unclear, an MSDS report is required.
| Laboratory Testing | Immersion testing requires a full 24 hours (not expedited).
| Report Preparation | Verify the consistency between the product images in the report and the sample.
| Customs Clearance Assistance | A Declaration of Conformity (DoC) can be requested from the testing agency.
