TESTED TO PERFORM IN EXTREME COLD EN 342 STANDARD AND THERMAL MANIKIN TESTING We test our garments to ensure workers are protected in the extreme cold.

EN 342

The principal test in EN 342:2017 uses a heated manikin. During the test, the manikin is heated to and maintained at a specified temperature. Thermal insulation is determined from the power required to maintain the manikin surface at this constant temperature. The resulting effective insulation value is used to classify the per formance of the garment. It can also be used to estimate the maximum duration of wear based on the activity level of the wearer, the temperature of the environment and the insulation value of the clothing. Clothing claiming to meet the requirements of EN 342 must be marked with the pictogram shown below.
