EN 511

Cold Protection Gloves

Working in cold environments requires reliable hand protection. The EN 511 cold protection gloves standard defines how gloves are tested and rated against low temperatures, wind chill, and moisture exposure.

This European standard applies to all gloves designed to protect hands in temperatures as low as –50°C.

Unlike EN 407, which measures heat resistance, EN 511 evaluates how effectively a glove insulates against cold conditions.

What Is EN 511?

EN 511 is a European testing standard that measures a glove’s resistance to:

Convective cold (cold air and wind)

Contact cold (cold surfaces)

Water penetration

The rating does not correspond to a specific temperature. Instead, it measures thermal insulation performance.

How EN 511 Ratings Work

The EN 511 marking shows a snowflake symbol followed by three numbers:

ABC

Where:

A – Convective Cold Resistance (0–4)

B – Contact Cold Resistance (0–4)

C – Water Permeability (0–1)

Higher numbers indicate better protection.

For example:

Contact Cold Level 2 provides more insulation than Level 1.

Level 4 offers the highest thermal resistance.

Level 0 means no measurable protection.

When selecting EN 511 cold protection gloves, always compare these performance levels to your working environment.

EN 511 Testing Methods Explained

1. Convective Cold Performance (A)

This test measures resistance to cold air.

A heated hand model is maintained at body temperature.

The surrounding air temperature is reduced to approximately 20°C below the hand temperature.

Controlled airflow simulates wind exposure.

Electrical energy required to maintain warmth is measured.

The more energy required, the poorer the insulation performance (ITR).

Less energy required means better resistance to convective cold.

This test shows how well gloves protect workers in outdoor or refrigerated environments.

2. Contact Cold Performance (B)

Contact cold testing measures how well a glove insulates against direct contact with cold objects such as metal tools or frozen surfaces.

Thermal resistance is measured when the glove material touches a cold plate. Ratings range from 0 to 4.

Higher ratings mean:

Slower heat transfer

Better insulation

Greater warmth retention

3. Water Permeability (C)

Gloves are tested for resistance to water penetration over a fixed period.

0 = Water penetration detected

1 = No water penetration

Waterproof gloves help maintain insulation, as moisture significantly reduces thermal performance.

Why EN 511 Cold Protection Matters

Cold exposure can lead to:

Reduced dexterity

Decreased grip strength

Numbness and discomfort

Increased risk of frostbite

Choosing the correct EN 511 cold protection gloves improves safety, productivity, and comfort in cold working conditions.

How to Choose the Right EN 511 Gloves

When selecting gloves, consider:

Indoor vs outdoor work

Wind exposure

Surface contact temperature

Moisture exposure

Required dexterity level

Higher EN 511 ratings generally provide better insulation but may reduce flexibility. Balance protection with task requirements.
