1 Scope
This document specifies technical requirements, labeling, and manufacturer's information for cold-protective gloves (hereinafter referred to as "gloves"), along with corresponding test methods.
Applicable to gloves protecting against low-temperature injuries in climatic environments or work activities down to -50°C.
Excludes: Gloves with heating functions.

3.1 Convective Cold
A glove's ability to resist hand heat loss through convective heat transfer.
Note: Expressed as convective thermal resistance.
3.2 Contact Cold
A glove's ability to inhibit heat transfer through conduction.
Note: Expressed as contact thermal resistance.
4 Technical Requirements
4.1 General
Gloves shall meet requirements in Table 1, with at least one of convective/contact cold criteria satisfied.
4.2 Basic Requirements
Comply with GB 42298 specifications.
4.3 Mechanical Properties
4.3.1 Abrasion Resistance
Minimum Level 1 per Table 2 when tested per 5.2.1. Higher cold protection levels (2-4) require Level 2.
4.3.2 Tear Resistance
Minimum Level 1 per Table 3 when tested per 5.2.2. Higher cold protection levels (2-4) require Level 2.
4.4 Flex Resistance
No cracks when tested per 5.3 (Appendix A). Non-coated materials exempt.
4.5 Water Resistance
Grade 1 = no penetration; Grade 0 = penetration (requires manufacturer warning about reduced cold protection when wet).
4.6 Low-Temperature Flexibility
For gloves used at -50°C to -30°C: No cracks when tested per 5.5 (Appendix B).
4.7 Convective Cold
Graded per Table 4 when tested per 5.6 (Appendix C). Levels 2-4 require minimum Level 2 abrasion/tear resistance.
4.8 Contact Cold
Graded per Table 5 when tested per 5.7 (Appendix D). Levels 2-4 require minimum Level 2 abrasion/tear resistance.
