EN 511 Cold Protection HeaderThis standard defines the protection levels against cold hazards but is very different from the tests for heat and often causes confusion. Unlike the EN 407 standard for heat, it does not relate to any particular temperature. In practice it is only really useful in comparing different gloves, for example, a glove with contact cold level 2 is warmer than a glove with contact cold level 1. A more detailed explanation of the actual tests is detailed below for reference.

As you will note the physical test results are very difficult to understand and for most people difficult to directly relate to real-world situations. They are included below for A – Convective cold performance is tested using a model of a hand which is typically heated to around body temperature. The outside temperature is reduced to at least 20 °C below the hand temperature with a carefully regulated airflow. The amount of electrical energy needed to maintain the temperature gradient, in simple terms to keep the hand warm, is measured to give an indication of the insulation properties of the glove. The more power needed, the worse the glove’s thermal insulation (ITR) properties.
