《GB/T 15067.2-2016不锈钢餐具》由TC410（全国金属餐饮及烹饪器具标准化技术委员会）归口，主管部门为中国轻工业联合会。

ChinaStandards.net is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative.

This standard is developed according to the rules of GB/T 1.1-2009.

This standard replaces GB/T 15067.2-1994 Stainless Steel Curtlery.

The following main technical changes have been made with respect to GB/T 15067.2-1994:

——The product grade classification (Chapter 4 of 1994 edition) is deleted;

——Appearance requirements in former standard are subdivided into dimension, shape, appearance and surface roughness and relevant requirements are made;

——The corrosion resistance and blade hardness requirements are modified.

This standard was proposed by the China National Light Industry Council.

This standard is under the jurisdiction of National Technical Committee on Metal Catering and Cooking Appliances of Standardization Administration of China (SAC/TC 410).

The previous edition of this standard is as follow:

——GB/T 15067.2-1994.

Stainless Steel Cutlery

1 Scope

This standard specifies the requirements, test methods, inspection rules as well as marking, packaging, transportation and storage of stainless steel cutlery.

This standard applies to the cutleries whose food contact parts are made of stainless steel by processing forming.
