China | Silicone Rubber Materials and Products for Food Contact | Draft National Food Safety Standard



China has released the draft National Food Safety Standard for Silicone Rubber Materials and Products for Food Contact. This draft standard establishes requirements and testing procedures for ensuring the safety of silicone rubber materials and products that come into contact with food. Here's a summary of the key points from the draft standard:

  1. Scope: The standard applies to silicone rubber materials and products that come into contact with food or food additives under normal usage conditions.

  2. Terminology: It provides definitions for terms relevant to food-contact silicone rubber materials and products.

  3. Basic Requirements: These materials and products should comply with the provisions set forth in GB 4806.1, which presumably contains general food safety regulations.

  4. Technical Requirements:

    • Raw Materials: It specifies requirements for the base materials used in food-contact silicone rubber materials and products, referencing Appendix A and related announcements.
    • Sensory Requirements: These materials and products should meet certain sensory requirements, as detailed in Table 1.
    • Physicochemical Parameters: General physicochemical parameters are provided, as shown in Table 2.
  5. Other Technical Requirements: If these materials or products contain coatings, inks, adhesives, or similar substances, they must also meet the relevant national food safety standards for these materials.

  6. Migration Testing: Migration testing should follow GB 31604.1 and GB 5009.156, with specific conditions detailed in the standard.

  7. Labeling and Marking: Labeling and marking should comply with the provisions of GB 4806.1.

  8. Appendices:

    • Appendix A: Lists permitted base materials and their usage requirements.
    • Appendix B: Provides a method for determining volatile substances in food-contact silicone rubber materials and products.
  9. Precision: The document outlines precision requirements for determining the volatile substance content in the samples, specifying acceptable differences between independent measurements.

  10. Calculation of Volatile Substance Content: The standard includes a formula for calculating the content of volatile substances in the samples.

  11. Repeatability: Specifies the acceptable limits of differences in results when testing volatile substances, depending on their content.
