Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting. This document replaces GB/T 38304-2019 "Hand Protection Gloves for Cold Weather". Compared with GB/T 38304-2019, the only changes are structural adjustments. Aside from editorial changes, the main technical changes are as follows:

---The scope of application has been changed (see Chapter 1, Chapter 1 of the.2019 edition);

---The requirements for convection cooling and contact cooling of gloves have been changed (see 4.1,.2019 version 4.1);

---The test methods for abrasion resistance, tear resistance, and water resistance have been revised (see 5.2.1, 5.2.2, and 5.4;

5.2.2 in the.2019 version). and 5.4);

---The test location and temperature requirements for flexural destructive testing have been changed (see

5.3 and Appendix A,

5.3 in the.2019 edition);

---The test location for low-temperature bending performance has been changed (see

5.5 and Appendix B,

5.5 in the.2019 edition);

---The test location for convection cooling has been changed (see

5.6 and Appendix C,

1 Scope

GB 38304-2025 is the Chinese national standard on hand protection - protective gloves against cold, in the field of environment and health protection, safety. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 29 August 2025 by the Ministry of Emergency Management, and has been in force since 1 September 2026. Classification: ICS 13.340.40, CCS C73. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the technical requirements, markings, and manufacturer-provided information for protective cold-weather gloves (hereinafter referred to as "gloves"), and describes the testing... Try different methods. This document applies to gloves designed to protect against low-temperature injuries in climates or work activities with temperatures as low as -50°C. This document does not apply to gloves with heating functions.
