PROTECTION AGAINST HEAT AND FLAME

Protection against heat and flame. This standard specifies the performance requirements of materials and protective clothing against heat and flames. They apply to clothing made of soft material, designed to protect the human body except the hands against heat and/ or flame.
Tested are:

MAIVE2
	EN ISO 11612
	A1 A2 B1 C1 E3 F1

PROTECTIVE CLOTHING AGAINST COOL ENVIRONMENTS

This standard specifies the requirements and performance test methods for protective garments (vests, jackets, coats, trousers) against cool environments.

These garments are for use in moderate low temperatures (-5°C and over) to protect against local body cooling. Not only for outdoor use such as in the construction industry; may also be used for indoor activities, such as in the food processing industry.

These garments are not always necessarily made of air impermeable or watertight materials.

Therefore, in this European standard, these requirements are optional.

X : Class of heat resistance, Rct

X : Class of air permeability, AP

X : /cler of the garment (Optional)

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:

Requirements for chemical protection clothing with liquid-tight (type 3) or spray-tight (type 4) connections, including items providing only partial body protection (types PB [3] and PB [4]).

This standard sets out the minimum requirements for the following types of limited use and reuseable chemical protective clothing:

- Clothing protecting the full body with liquid-tight connections between the various clothing parts (Type 3: liquid-tight clothing) ;
- Clothing protecting the full body with spray-tight connections between the various clothing parts (Type 4: spray-tight clothing) ;
 

a - When the protective equipment only protects certain parts of the body (torso, arms, legs), only the performance requirements for the materials making up the garment are required required (types 6, 4 and 3).

PROTECTION USED IN WELDING AND ALLIED PROCESSES

This standard specifies the performance requirements for protective clothing for use by operators in welding and allied processes with comparable risks. This type of protective clothing is intended to protect the wearer against molten metal splash, short contact with flame and UV radiation. It is intended to be worn at ambient temperature, continuously for up to 8 hours.
