EN 343 Logo


EN 343 – Protective Clothing, Protection Against Rain

EN 343 is the harmonised European standard that applies to garments worn in adverse weather conditions. It specifies the characteristics of protective clothing against the influence of foul weather, wind and cool above -5°c. The standard provides for two performance parameters:

X = Waterproofness (3 levels)

Y = Breathable properties (3 levels)

RIS 3279 Logo


RIS-3279-TOM Issue 1 has replaced GO/RT 3279. Railway Industry Standard (RIS) sets out the minimum specication for high visibility warning clothing in the Rail Industry.

EN 510 Logo

EN 510 – Protective Clothing for use where there is a Risk Of Entanglement from Moving Parts

This standard specifies the properties of protective clothing that minimise the risk of its entanglement or drawing-in by moving parts when the wearer is working on or near hazardous moving machines or devices.

EN 1150 Logo

EN 1150 – Visibility Protective Clothing for non-professional use

This European standard specifies the optical performance requirements for high visibility clothing to be worn by adults and by juveniles, and designed for non-professional use.

Oeko Tex Logo


High Visibility fabrics tested to the Oeko Tex standard guaranteeing fabric does not contain any harmful substances detrimental to human health.

EN 13356 – Visibility Accessories for Non Professional Use

This standard specifies the optical performance requirements for accessories which are to be worn, attached to or carried by people and designed for non-professional use. Visibility accessories complying with this standard are intended to signal the users presence visually when illuminated by vehicle headlight on dark roads.

ISO 13688 – Protective Clothing – General Requirements

This international standard specifies general requirements and recommendations for ergonomics, ageing, sizing and marking of protective clothing, and for information supplied by the manufacturer.

Every certified garment in this brochure is also certied to ISO 13688. This standard replaces the old EN340 standard.

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.

EN 342 Logo

EN 342 Protective Clothing – Ensembles and Garments for Protection Against Cold





EN 342 is the harmonised European standard that specifies requirements and test methods for performance of clothing ensembles (ie. two piece suits or coveralls) and of single garments for protection against cold environments.

Garments are tested under the following performance parameters as shown on the pictogram below:

Thermal insulation

This is tested on a moving manikin. The unit of measurement is Icler and is stated in m2. It measures the amount of energy per square metre required to maintain warmth – the higher the number, the better the rating. X indicates the Thermal Insulation test on a stationary manikin and is not a compulsory part of the standard. The unit of measurement is Icle and is stated in m2.

Air Permeability

Air Permeability measures the ease with which the air can pass through the material. It is a measure of how wind proof the garment is and again the higher the number the better the result. The air permeability on the example below achieves a Class 3.

Resistance to Water Penetration

The final result is Resistance to Water penetration, which achieves a Class 2 below. This is an optional test.

Results shown below are for S485 Hi-Vis Contrast Coverall.
