RAIN
EN 343:2019
This standard specifies the requirements and test methods applicable to materials and stitching of protective clothing against the effects of precipitation( e. g. rain, snow), fog and soil moisture.- The number located in place of the X indicates the class of the resistance level to water penetration( Wp).- The letter Y indicates the class of resistance level to water vapour( Ret) equivalent to breathability.- The letter R( optional) indicates that the garment has undergone the rain tower test to check its resistance to impact with high-energy droplets.

COLD ENVIRONMENTS
EN 14058:2017 + A1:2023
This standard specifies requirements and test methods for the performance of protective clothing against the effects of cold environments at-5 ° C.. These effects include not only low air temperatures, but also humidity and air velocity.- The number located in place of the first Y indicates the class of thermal resistance level( Rct)- The number located in place of the second Y indicates the class of air permeability level( AP)- The number located in place of the third Y indicates the class of thermal insulation level( Icler)- WP( optional) indicates waterproofing
