EN 511:2010 is a European standard that specifies the requirements for protective gloves against cold. The standard sets out different performance levels for gloves, based on their ability to provide insulation against convective and contact cold, as well as resistance to water penetration. EN 511:2010 is applicable to gloves used in various industries and environments where protection against cold is necessary.
Temperature Ratings
The temperature ratings of gloves under EN 511:2010 are indicated using three numbers, each representing a different performance level. The first number indicates the resistance to convective cold, the second number represents the resistance to contact cold, and the third number reflects the water penetration resistance. The higher the number, the better the glove's performance in providing protection against that specific element.
Convective Cold Resistance
The first number in the temperature rating refers to the glove's resistance to convective cold. Convective cold is caused by the flow of cold air around an individual. The EN 511:2010 standard assigns performance levels ranging from 0 to 4 for convective cold resistance, where 0 offers minimal protection and 4 provides excellent insulation against convective cold. Gloves with high convective cold resistance are ideal for outdoor activities or working in cold environments with strong winds.
Contact Cold Resistance
The second number in the temperature rating indicates the glove's resistance to contact cold. Contact cold occurs when an individual comes into direct contact with a cold object or surface. Like the convective cold resistance, the performance levels for contact cold resistance range from 0 to 4. Gloves with high contact cold resistance perform well in tasks that involve handling refrigerated products, working in freezers, or any activities that require prolonged contact with cold materials.
Water Penetration Resistance
The third number in the temperature rating signifies the glove's resistance against water penetration. The performance levels range from 0 to 1, where 0 indicates no water penetration resistance and 1 represents water penetration resistance. Gloves with high water penetration resistance are suitable for tasks that involve working in wet or damp environments where maintaining dry hands is essential.
Conclusion
EN 511:2010 provides a comprehensive framework for assessing the performance of protective gloves against cold. Its temperature rating system allows users to easily identify gloves suitable for different cold-related tasks, ensuring adequate protection and safety in various industries and working conditions.
