What is EN 511-30-20-10

EN 511-30-20-10 is a technical standard that specifies the requirements for protective gloves against cold conditions. It provides guidelines for evaluating and classifying the performance of these gloves, allowing manufacturers and users to assess their suitability in various cold environments. Frostbite and other cold-related injuries can occur if proper protection is not used, making this standard essential in ensuring worker safety.

Understanding the Key Parameters

The EN 511-30-20-10 standard evaluates gloves based on three main parameters: resistance to convective cold, resistance to contact cold, and dexterity. Convective cold refers to the cold air that comes into direct contact with the glove material, while contact cold evaluates the glove's ability to insulate against cold objects. Dexterity measures how well the gloves allow the wearer to perform tasks requiring precision and fine motor skills while maintaining adequate protection against cold. By assessing these parameters, users can make informed decisions when selecting suitable gloves for their specific cold weather needs.

Testing and Classification

To determine compliance with EN 511-30-20-10, gloves undergo rigorous testing. Resistance to convective cold is measured by exposing the glove to cold air at a specific temperature and airflow rate, while resistance to contact cold is evaluated by measuring the temperature reduction experienced by a metal probe in contact with the glove. Dexterity is assessed using a range of practical tests, including manipulation of small objects and dexterity tasks. Gloves that meet the minimum requirements for each parameter are classified accordingly, with higher numbers indicating better performance.

Application and Considerations

EN 511-30-20-10 enables companies and individuals to make informed decisions when selecting protective gloves for cold conditions. Workers operating in cold environments, such as freezer warehouses or alpine regions, can use this standard to ensure their gloves provide adequate protection against cold-related risks. It is crucial to consider the specific working conditions, duration of exposure, and level of dexterity required when choosing gloves. Compliance with EN 511-30-20-10 ensures that gloves have been tested and classified according to established standards, enhancing safety and reducing the risk of cold-induced injuries.
