e) Added health and safety performance requirements and test methods (see 4.2 and 5.2);

f) Added requirements and test methods for antibacterial durability (see 4.3 and 5.3);

g) Added requirements for Candida albicans (see 4.3);

h) Added requirements for the microstructure morphology of the covering layer and test methods (see 4.4 and 5.4.1);

i) Change "Packaging, Marking and Quality Certificate" to "Labeling, Packaging, Transport and Storage" (see Chapter 7, Chapter 8 of the 2009 edition chapter).

Introduction

Surface antibacterial stainless steel materials and their products are mostly used in food and water-related fields, and are closely related to people's health. To make standards more operational sex, applicability and scientificity, resolve issues such as technological progress and user concerns during the implementation process, and better guide surface antibacterial stainless steel steel The application of its products and the protection of users' health require revision of this national standard. According to surface antibacterial stainless steel and its products According to the process characteristics, GB/T 24170 is planned to consist of the following three parts.

---Part 1: Electrochemical method. The purpose is to provide sanitary protection for surface antibacterial stainless steel and its products obtained by electrochemical methods. Health safety and antibacterial performance requirements and their measurement methods.

---Part 2: Plasma method. The purpose is to provide surface antibacterial stainless steel and its products obtained by plasma method. Hygienic safety and antimicrobial performance requirements and methods of measurement.

---Part 3: Ion implantation method. The purpose is to provide antibacterial surface antibacterial stainless steel and its products obtained by ion implantation. Provides hygienic safety and antibacterial performance requirements and their measurement methods.
