What are the standards for food-grade and sanitary-grade fittings?
Thread Content
I would like to ask everyone: In equipment manufacturing plants, when dealing with equipment intended for the food industry or pharmaceutical factories, and when food-grade or sanitary-grade fittings are required, what standards should be followed for procurement? Are there **standards or international standards?** Thank you.
The standards for food-grade and sanitary-grade fittings are as follows: 1. ****Standards (GB standards)**: - GB 4806 series: General safety requirements for materials and products in contact with food. - GB/T 26121 series: Properties and requirements for stainless steel food-contact materials. 2. **International standards**: - **U.S. Food and Drug Administration (FDA)**: Title 21 CFR Part 177, applicable to materials that come into contact with food. - **3-A Sanitary Standards**: Specifically applicable to dairy products, food, and sanitary equipment; stainless steel fittings must comply with these standards. - **ISO 22000**: Food safety management system standard; although it does not directly specify materials, it relates to overall safety regulations. - **EHEDG** (European Hygienic Engineering and Design Group): Provides hygiene design guidelines for the food industry. These standards are typically referenced during procurement to ensure compliance with relevant safety and hygiene requirements. .
