Specification

EN 340
General requirements of the protective garments, used only in combination with specific standards such as EN342 etc. General requirements are for ergonomics, aging, sizing, and marking of protective clothing, and for information supplied by the manufacturer.

Category I Standards EN 342, EN 343

EN 342: Protection against cold

Products are tested by measuring the insulation for an ensemble (jacket, trouser) worn. Air permeability and breathability are also measured. Figures (1, 2 or 3) are given against X for insulation, Y for air permeability and Z for breathability; higher figures are best

X Insulations, actual data (higher figure is best) Y Air permeability, level 1, 2 or 3 Z Breathability, level 1, 2 or 3

EN 343: Protection Against Foul Weather

These garments are intended to protect against weather conditions with combinations of precipitation, rain, fog, humidity and wind at temperatures down to +5°C. They are tested for being waterproof (X) and breathability (Y); figures (1, 2 or 3) are given and higher figures are best.

X Waterproof quotient, level 1, 2 or 3 Y Breathability, level 1, 2 or 3

Category II:  EN 471 High Visibility Clothing

The standard specifies requirements for clothing intended to provide and enhance the visibility of the user in hazardous situations under any light conditions by day and under illumination by vehicle headlights in the dark (24 hours visibility). Effective visibility is to be provided by a fluorescent fabric and reflective stripes. The visibility is measured as a combination of the area and positioning of the reflective materials (X) and the quality of same (Y).

X Area reflex/fluorescent fabric, level 1, 2 or 3 Y Reflex type/quality 1 or 2

Class 1

Class 1 defines the lowest visibility level e.g. High Visibility trousers with two 5cm reflective bands around each leg. These become Class 3 when worn with a Class 3 jacket

Class 2

The class 2 defines an intermediary visibility level. Example: vests. Two 5cm bands of reflective material around the body or one 5cm band around the body and braces to both shoulders.

Class 3

The class 3 defines the highest level of visibility. For example jacket with long sleeves, jacket and trouser suit. Two 5cm bands of reflective tape around the body and arms plus braces over both shoulders are also shown.

EN13034: Protective Clothing Against Liquid Chemicals

Performance requirements for the combinations of chemical protection of limited use and reusable garments offer a limited protection against the exposure to the liquid aerosols, fog and the light splashes where the type of potential exposure, for, mist, etc. is defined.

EN1073 - 2: Protective clothing against radioactive contamination.
Requirements and test methods for non-ventilated protective clothing against particulate radioactive contamination
