What is EN ISO 27338:2011

EN ISO 27338:2011 is an international standard that provides guidelines for the evaluation and selection of heat stress protective clothing. The standard specifies the requirements for materials used in such clothing, including thermal resistance, water vapor permeability, and resistance to liquid and gas penetration. It also covers the design and performance criteria for protective clothing systems to ensure proper protection against heat stress.

Benefits of EN ISO 27338:2011

By following the guidelines provided in EN ISO 27338:2011, organizations can ensure the safety and well-being of workers exposed to high temperatures in various industries, such as firefighting, metallurgy, and construction. The standard helps in selecting suitable materials with high thermal resistance that can minimize heat transfer from the environment to the wearer's body. Additionally, it ensures appropriate moisture vapor permeability to prevent heat buildup and allows for efficient evaporation of sweat.

Understanding the Testing Methods

The standard outlines specific testing methods to evaluate the heat resistance, water vapor permeability, and other properties of protective clothing materials. These methods include measurement of thermal insulation using a thermal manikin, determination of water vapor transmission rate through garments, and assessment of resistance to liquid and gaseous chemicals using various test apparatus. Compliance with these testing methods assures the reliability and performance of the clothing system.

Implementation Challenges and Solutions

Implementing EN ISO 27338:2011 may pose some challenges for organizations. One common challenge is the cost associated with procuring specialized materials that meet the required standards. Another challenge is maintaining comfort and mobility while providing sufficient protection. To overcome these challenges, organizations can collaborate with textile manufacturers to develop innovative materials that are both protective and comfortable. They can also invest in regular training sessions to educate workers on the importance of proper usage and maintenance of heat stress protective clothing.
