Protective clothing against cold
EN 342 specifies the requirements and performance of clothing designed to protect against cooling of the body in cold environments. It is possible to certify single garments as well as an entire outfit in several layers.
Wearing several layers is a great way of increasing insulation and enhance the protection against cold. The layered outfit also makes it easy to adjust to rapid temperature changes.
Remember that sweating should be avoided during continuous cold exposure, since moisture absorption will progressively reduce insulation. In addition, wind increases the need for protection.
The EN 14058 norm is closely related to EN 342. EN 14058 requires a lower level of protection and targets clothing designed for work in cool environments i.e. cold stores (refrigerated area for keeping foods etc.)
