Compliance overview
Scope and applicability
GB 16798-2023 applies to machinery and equipment utilized in the food processing process. It specifically targets food machinery involved in the preprocessing, manufacturing, storage, transportation, and packaging of food products. This standard is mandatory for all manufacturers producing equipment for the Chinese food industry. It does not apply to machinery used in non-food industries or equipment that does not have direct or indirect contact with food products.
Technical requirements
The standard specifies comprehensive material requirements for product contact surfaces and non-contact surfaces. Materials must possess product compatibility, ensuring they do not transfer harmful substances, affect product odor/color, or degrade under cleaning and disinfecting conditions. Manufacturers must ensure all materials meet strict safety, traceability, and corrosion resistance criteria. For equipment structure, the standard mandates the elimination of dead corners and product retention areas. It sets specific geometric tolerances, such as minimum radii for internal angles, to ensure cleanability. The design must facilitate both manual and automatic cleaning, including Clean-in-Place (CIP) and Steam-in-Place (SIP) capabilities. Equipment must be designed to be easily disassembled, inspected, and thoroughly cleaned without requiring special tools. Regarding mechanical and electrical safety, the standard requires protective measures for exposed moving parts, compliance with hydraulic and pneumatic system standards, and specific safeguards for pressure vessels. Equipment must feature safety interlocks on access doors and clear warning labels. Electrical systems must meet insulation and protection circuit requirements, and operational parameters like noise levels and surface temperatures are strictly regulated to ensure operator safety.
Testing methods
The standard outlines several key evaluation procedures, including insulation resistance testing and dielectric strength testing for electrical safety. It also requires verification of surface roughness (Ra values) for both product contact and non-contact surfaces. Manufacturers must verify the cleanability and inspectability of equipment surfaces, often through sensory evaluation methods and verifying rinse procedures.
FAQs
What products are regulated under GB 16798-2023?
The standard applies to machinery and equipment used in food processing processes. It covers safety requirements for structural materials, equipment structure, and installation, specifically targeting food machinery with product contact surfaces.
Are there any updates from the previous version of GB 16798-2023?
Compared to the 1997 version, the 2023 revision updates the scope, terms and definitions, structural material requirements, and equipment structure requirements. It also adds a new chapter on the implementation of the standard, which provides a transition period for existing facilities.
How does GB 16798-2023 differ from ISO standards?
The standard heavily references Chinese national (GB) and industry (QB) standards for specific materials like stainless steel and aluminum alloys. While it aligns with general international safety principles, manufacturers must ensure their materials meet the specific Chinese grade requirements detailed in the referenced standards to achieve compliance.
