What Is EN 343?

What Is EN 343?

EN343 is the European standard that applies to garments worn in adverse weather conditions. This standard specifies requirements and test methods applicable to the materials and seams of protective clothing against the influence of precipitation (e.g. rain, snowflakes), fog, and ground humidity.

What Is EN 343? - Pictogram Explanation

What Is EN 343? - Pictogram Explanation

The pictogram to the left indicates that protection against rain is offered.

The standard provides for two performance parameters of which there are 4 levels with Class 4 offering the highest level of protection.

  • X - Water Penetration Resistance (Waterproofness) 4 Levels
  • Y - Water Vapour Resistance (Breathability) 4 Levels
  • R - Readymade Garment; Rain Tower Test (optional)
    R may be replaced by an X if the test has not been carried out or is not suitable.

What Is EN 342?

What Is EN 342?

EN342 is the European standard that applies to garments worn in cold environments. This standard specifies requirements and test methods for the performance of clothing ensembles (i.e two-piece suits/coveralls) for protection against the effects of cold environments equal to or below -5°C.

There are three main parameters:

  • A - Thermal insulation (this is tested using a full-size moving mannequin & measures the amount of energy required to maintain warmth)
  • B - Air Permeability (This is a measure of how windproof the garment is), AP, Class 1-3 (where 3 is best)
  • C - Water penetration (waterproofness) Class 1-2 (where 2 is best); optional test

(Example to the left refers to the Portwest Hi-Vis Bomber Jacket (S463) test results)

What Is EN 342? - Wear Time Example

What Is EN 342? - Wear Time Example
What Is EN 342? - Wear Time Example

The manikin test measures the amount of energy required to maintain warmth. This result is expressed in square metres Kelvin per Watt (m2K/W) this result can be used to estimate the maximum wear time based on the activity level of the wearer, the temperature of the environment and insulation value of the garment.

For example (see chart to the left):

A person wearing the Portwest Hi-Vis Bomber Jacket (S463) performing light activity can withstand -2°C for 8hrs and -18°C for 1hr. A person performing Medium activity can withstand -18°C for 8hrs and -36°C for 1hr.
