EN 342:2017
EN 342:2017 is the latest version of this European standard which replaced the previous version of EN 342:2004.
The EN 342:2017 update introduced several amendments to the previous version of the standard. Some of the key changes include:
- Revised testing methods to determine the thermal insulation properties of protective clothing
- Enhanced requirements for water penetration resistance
- Updated performance levels for thermal insulation and air permeability
- Improved labelling requirements
These updates were introduced to ensure the EN 342 standard to reflect advancements in materials, testing methods, and industry best practices, ensuring protective clothing is effective and reliable.
EN 342 requirements and test methods
EN 342 sets specific requirements and test methods for protective clothing designed to protect the wearer against cold environments. The requirements of EN 342 cover thermal insulation properties, air permeability, and waterproof penetration properties.
Within EN 342, performance levels are assigned to each test method. These performance levels are then used to determine the level of cold environment protection offered by the tested garment. This will be displayed on the EN 342 certified ensembles and garments with a pictogram featuring associated codes.
As well as outlining specific requirements related to cold environment insulation and protection, EN 342 also requires the garments to undergo durability tests and a fit and ergonomic assessment.
Thermal insulation properties with motion
The EN 342 requirements and test method for thermal insulation properties with motion determines the garment’s ability to retain heat and provide warmth in cold conditions while the wearer is moving. This test simulates real-world working conditions where physical activity may generate heat.
The test method requires a test subject to perform specific movements in a controlled cold environment. The heat loss from the wearer’s body is measured to determine the garment’s thermal insulation properties with motion. This is measured in units of Icler (m².K/W).
