e) The requirements for "appearance" and "corrosion resistance" in the general requirements have been changed (see 5.1.1, 5.1.4, and

5.1.4 in the.2013 edition);

f) Added requirements for "dimensional dimensions", "welding quality", "thermal insulation", "stability", and "hot water resistance of sealing rubber parts" to the general requirements. (See 5.1.2, 5.1.7, 5.1.8, 5.1.9, 5.1.10) and test methods (see 6.2.2, 6.2.7, 6.2.8, 6.2.9, 6.2.10);

1 Scope

GB/T 29601-2025 is the Chinese national standard covering stainless steel kitchenware - the grades allowed for food contact and the migration of chromium, nickel and manganese from them, the wall thickness and the finish, the handle attachment and its heat, and the marking that tells the buyer which grade he is holding. The migration limits are the point: cheap high-manganese grades sold as stainless are a recurring problem. Issued on 5 October 2025, it takes effect on 1 November 2026, replacing GB/T 29601-2013.
