When sourcing or selling protective gloves on Alibaba.com, understanding temperature rating standards is critical for matching products to buyer needs. Unlike generic "winter gloves" or "heat-resistant gloves," certified temperature ratings provide objective, testable performance benchmarks that B2B buyers rely on for procurement decisions.
The three primary standards governing thermal protection in gloves are EN 511 (cold protection), EN 407 (heat resistance), and ANSI/ISEA 105-2024 (comprehensive hand protection classification). Each serves different applications and geographic markets [2].
EN 511 is the European standard for protective gloves against cold. The pictogram features a snowflake symbol followed by three numbers. The first digit represents convective cold protection (Level 1-4, with Level 4 offering protection down to -50°C). The second digit indicates contact cold resistance (Level 1-3). The third digit is a binary pass/fail for water penetration (1 = waterproof after 30 minutes submersion, 0 = not waterproof).
It's important to note that EN 511 differs from EN 388 (mechanical risks like cut/abrasion) and EN 407 (thermal risks from heat). A glove can carry multiple certifications depending on its intended use [2].
EN 511 Cold Protection Rating Breakdown
| Rating Level | Convective Cold Protection | Contact Cold Resistance | Typical Application |
|---|---|---|---|
| Level 0 | No protection tested | No protection tested | Not suitable for cold environments |
| Level 1 | Down to -5°C approximately | Low thermal resistance | Refrigerated warehouses (0°C to 5°C) |
| Level 2 | Down to -15°C approximately | Moderate thermal resistance | Cold storage (-10°C to -20°C) |
| Level 3 | Down to -30°C approximately | Good thermal resistance | Freezer applications (-25°C to -35°C) |
| Level 4 | Down to -50°C | High thermal resistance | Extreme cold industrial use (-40°C to -50°C) |
EN 407 covers thermal risks from heat and fire. The standard uses a 6-digit code, with each digit representing performance in one of six tests: burning behavior, contact heat, convective heat, radiant heat, small molten metal splash, and large molten metal splash. Each test is rated 0-4, with Level 4 indicating maximum protection.
Testing temperatures range from 100°C to 500°C depending on the specific test. For contact heat, Level 1 requires withstanding 100°C, while Level 4 requires withstanding 500°C for at least 15 seconds with no more than 10°C temperature rise on the inner surface [3].
ANSI/ISEA 105-2024 is the American National Standard for Hand Protection Classification. The 6th edition, published in 2024, provides a voluntary industry consensus standard covering cut resistance (9 levels A1-A9), abrasion, puncture, chemical protection, and heat/cold protection. Unlike EN standards, ANSI/ISEA 105 does not cover extreme temperature extremes as its primary focus—it's more commonly used for cut and mechanical protection ratings in North American markets.
For Southeast Asian exporters selling on Alibaba.com, understanding which standard applies to which market is crucial: EN standards dominate European and Commonwealth markets, while ANSI is preferred in North America. Many buyers on Alibaba.com specifically search for gloves with both certifications to maximize market reach [1].
