EN 511:2010 is a technical standard used to assess the protective properties of gloves against cold. This standard specifies requirements and test methods to determine the glove's thermal insulation properties, resistance to water penetration, and resistance to water absorption.
The Requirements of EN 511:2010
In accordance with EN 511:2010, gloves are rated on a three-tier scale for their ability to protect against convective cold, contact cold, and water penetration. The first number indicates the level of protection against convective cold, which refers to heat transfer through the air. The second number measures resistance to contact cold, where lower numbers indicate better insulation against cold surfaces. The letter 'X' represents water penetration resistance, with a rating of '1' indicating no resistance, and '0' signifying resistance to water penetration.
Testing Methods for EN 511:2010
To comply with EN 511:2010, gloves undergo rigorous testing procedures. Thermal insulation is measured by the amount of energy required to maintain a temperature difference across the glove material. This test assesses how well a glove can retain heat. Water penetration resistance is evaluated using the hydrostatic pressure test, which determines the glove's ability to withstand water penetration under static conditions. Lastly, water absorption testing measures how much water is absorbed by the glove material when subjected to pressure in a water bath.
Importance of EN 511:2010
EN 511:2010 provides users with accurate information about the performance of gloves in cold environments. By understanding the different ratings and testing methods, individuals can select appropriate gloves based on the specific environmental conditions they will be facing. Whether it is protecting against convective or contact cold, or even against water penetration, gloves meeting the requirements of EN 511:2010 offer superior performance and enhanced safety.
