This standard specifies the requirements and test methods for non ventilated protective clothing against radioactive contamination in the form of particles.

Clothing of this type is designed only to protect the body, the arms and the legs of the wearer, but it may be used with accessories that protect other parts of the wearer’s body (for example, boots, gloves, respiratory protective device - APR).

The garments are classified according to their nominal protection factor (ratio between the concentration of test particles in the ambient atmosphere and the concentration of test particles inside the garment), determined in relation to the total inward leakage (ratio between the concentrations of test particles insider the garment and inside the test chamber).

The classes are as follows:

This standard specifies the requirements and performance test methods for protective clothing against cold at temperatures lower than -5°C (cold store / extreme cold workers).

There are two types of garment :

Garments: covering part of the body, e.g. parka, jacket, coat.

Suits: covering the whole body (trunk + legs), e.g. coveralls, parka & dungarees.

X (undergarment B/C/R) : /cler of the garment

X : Class of air permeability, AP

X : Class of resistance to water penetration WP (Optional)

HIGH VISIBILITY CLOTHING

This standard specifies the requirements for protective clothing aiming to signal the presence of the wearer visually, so that he may be detected and seen in hazardous situations, in all conditions of daylight, and night under illumination of car headlights.

There are three classes of high-visibility clothing. Each class must have minimum surfaces of visible material constituting the garment; the higher the class, the more visible the garment:

Marking : 

X : Class of high visibility surface (from 1 to 3)

EN ISO 20471  

2
Max. 25x

EN ISO 20471

2 : Class of hight visibility surface (from 1 to 3)

Max. 25x : Optional marking, number of maximum washes authorized for the model. On this example: 25 washes maximum (see indication of service temperature on the garment tag).

PROTECTIVE CLOTHING AGAINST RAIN

This standard specifies the requirements and test methods applicable to the materials and seams of protective clothing against foul weather (for example precipitation in the form of rain or snow), fog and ground humidity.

y : Class of resistance to water penetration (1 to 4), Wp

y : Class of water vapour resistance (1 to 4), Ret

R : Water tower test on whole garment (optional)

DEFINITIONS

THERMAL RESISTANCE (Rct) IN M².K/W:

Measurement of the thermal insulation provided.

Divided into 4 classes (from 1 to 4) from the least insulating to the most insulating.

The higher the value, the greater the thermal insulation.

AIR PERMEABILITY (AP) IN MM/S :

Determines the complex's permeability to air.

Divided into 3 classes (from 1 to 3) from the least airtight to the most airtight.

RESULTANT EFFECTIVE THERMAL INSULATION :

Measured on moving dummy (/cler).

The thermal insulation coefficient, expressed in m².K/W, is used to determine the optimum usage temperature of the garment in relation to the individual's activity and his exposure time.

Thermal insulation is measured with undergarments of type:

• (B) for ensembles (Undershirt with long sleeves, long underpants, socks, bootee + thermojacket, thermopants, knitted gloves, balaclava)
• (R) for garments (Undershirt with long sleeves, long underpants, socks, bootees, jacket, trousers, shirt, knitted gloves, balaclava)
• (C) provided by the manufacturer

WATER VAPOUR RESISTANCE (Ret) IN (M².PA)/W :

Measures the evaporative resistance, i.e. the product's obstacle to the passage of water vapour, or the barrier it offers to evaporation of transpiration on the surface of the skin. The higher a product's water vapour resistance, the greater this product's barrier to the passage of water vapour : 

A breathing product has a low water vapour resistance.

Divided into 4 levels (from 1 to 4) from the least breathable to the most breathable.

RESISTANCE TO WATER PENETRATION (WP) IN PASCAL:

Measurement of the outer material and seams' resistance to water penetration under a water pressure of (980+/-50) Pa/min.

Divided into 4 levels (1 to 4) from the least impermeable to the most impermeable.

TOWER TEST:
