WORKING IN EXTREME COLD

EN 342 STANDARD AND THERMAL MANIKIN TESTING

PW369

EN342 protection against cold is the most comprehensive standard test method for clothing designed to protect you in cold conditions. The principle test uses a heated manikin, a thermal insulation value is determined from the power required to maintain the manikin at a constant temperature. This value is used to classify the performance of the garment. This insulation value of the clothing, the activity level of the wearer and the temperature of the environment can be used to estimate the maximum duration of wear. Clothing that meets the requirement of EN342 will have the pictogram below on the label.

PW351

-22 0 C/ 8 hr -41 0 C/ 1 hr EN342 COLD TEMPERATURE RANGE This chart shows the clothing is tested for wear at medium activity levels, at the temperature and the time indicated. This example shows that a worker can wear the garment specified for a medium level activity for 8 hours at -22°C or for 1 hour at -41°C.

EN 14058 PROTECTIVE CLOTHING - GARMENTS FOR PROTECTION AGAINST COOL ENVIRONMENTS This standard specifies requirements and test methods for the performance of single garments for protection against cooling of the body in cool environments. Cool environments are as a result of a combination of humidity and wind at temperatures of -5°C and above. At moderate low

temperatures garments against local body cooling are not only used for outdoor activities but can be used for indoor activities. In these cases garments often do not need to be made of watertight or air impermeable materials. Therefore, these requirements are optional for this standard.
