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

Level C1 protective clothing is suitable when the potential risk is relatively low. Level C1 protective clothing provides the minimum protection and is not suitable for the handling of concentrated pesticide formulations. It can be used as basic protective clothing with other items when the potential risk is relatively higher.

Level C2 protective clothing, including partial body protection, is suitable when it has been determined that the protection required is greater than that provided by level C1 protective clothing. C2 level protective clothing generally offers a balance between comfort and protection. This protective clothing is not suitable for the handling of concentrated pesticide formulations. It can be used as basic protective clothing with other items when the potential risk is relatively higher.

Level C3 protective clothing, including partial body protection, is suitable when it has been determined that the potential risk is high. For level C3 protective clothing, precautionary measures, such as short-term use, are necessary, as these clothing can generate excessive heat, leading to exhaustion and heat stress. Level C3 protective clothing, including partial body protection, is suitable for the handling of diluted pesticides as well as concentrated pesticides.

The risk incurred should be assessed according to the toxicity of the phytosanitary product (refer to its labelling) and the degree of exposure to the operator. For example, it is easy to understand that the degree of operator exposure will be much higher with aerial spraying towed by an open cab tractor than with manual trigger spraying.

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)

IMPROVED VISIBILITY EQUIPMENT FOR MEDIUM RISK SITUATIONS

This standard specifies the requirements for enhanced visibility equipment in the form of a garment, or device, capable of visually signalling the presence of the user.

Enhanced Visibility Equipment is intended to provide visibility of the wearer in low or medium risk situations in all daylight conditions and/or under the illumination of vehicle headlights or headlights in the dark. This standard does not apply to high visibility equipment in high risk situations which are covered by EN ISO 20471.

Minimum surface in m² for B1 and B2 type:

Minimum surface in m² for type A, B3 and AB type:

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:

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.

Requirements for chemical protection clothing offering limited performance against liquid chemical products (type 6 equipment), including clothing for partial body protection (Type PB [6]).

This standard sets out the minimum requirements for limited use and reusable limited performance chemical protective clothing. Limited use chemical protective clothing is intended for use in cases of a potential exposure to light sprays, liquid aerosols or lowpressure, low-volume splashes, against which a complete liquid permeation barrier (at the molecular level) is not required.

PROTECTIVE CLOTHING TO DISSIPATE STATIC ELECTRICITY

This European Standard specifies requirements for materials and the design of protective electrostatic dissipation clothing used in conjunction with a grounded system in order to prevent incendiary discharges. WARNING: These requirements may be insufficient in oxygen enriched flammable environments. This standard is not applicable for protection against mains voltages.

The control of undesirable static electricity on the person is often necessary.

The electrostatic potential may, indeed, have serious consequences on the charged individual, because it can be high enough to cause dangerous sparks.

After a risk assessment, the wearing of protective electrical dissipation clothing may be necessary. The use of clothing certified according to EN1149-5 is then adapted.

The ATEX Directive 1999/92/EC, in its Annex II-A-2.3, requests that workers be equipped with work clothes made of materials that do not produce electrostatic discharges that can ignite
explosive environments.

The electrostatic potential can also affect equipment sensitive to electric discharge. Antistatic clothing is often used on electronic manufacturing sites, assembling semiconductors for example. Finally, they are used on sites with controlled atmospheres such as automotive paint workshops, to avoid the emission of particles that may be deposited on the body paint.

The antistatic charge dissipation can be provided by a process limiting the build up of charge, or by adding carbon or metal wires. People wearing protective electrostatic charge dissipation clothing must always be grounded with a resistance of less than 10⁸Ω, for example, by wearing appropriate footwear such as the safety shoes stated in EN ISO 20345, or by other suitable means.
