EN 343: Protection against rain
Resistance to water penetration and water vapor resistance.
- X: Resistance to water penetration(3 levels)
The resistance to water penetration is expressed in kPa or millimeter water column.
- Y:Water vapor resistance – Breathing properties(3 levels)
EN 343 uses a water vapor resistance value Ret(m2, Pa/W).
Breathable garments evacuate the perspiration away from the skin and from the garments.
EN 13758: UV Protective clothing
EN 13758-2 specifies the requirements for the marking of clothing which are designed to offer the wearer protection against solar UV exposure.
The clothing covers the upper body (torso, from the base of the neck down to the hip, and cross the shoulders down to ¾ of the upper arm) completely and/or the lower body(part of the body from the waist down to below the patella) completely.
The UPF (Ultraviolet Protection Factor) is larger than 40. (UPF 40+) The average UV-A(UV radiation between 35 and 400nm) transmission is smaller than 5%.
Draft IEC 61482: Protective clothing against thermal hazards of electric arc
An electric arc or blast as a result of a disruption (e.g. a short circuit) in an electric installation generates a sudden release of intense heat and light causing serious burns, blindness or even death.
This blazing bright electric discharge between two conducting electrodes.
- Lasts for a very short time (0.5s, 1s and rarely >1s)
- Develops a very strong radiant heat (several thousands °C)
- Creates high physical forces, a pressure wave and pressure shrapnel
- A splash of molten metal particles or even vaporized metal
- Up to 165 db noise
Draft IEC 61482-2 specifies requirements applicable to materials and garments (exct. Protection of head, hands and feel) for protective clothing for electrical workers against thermal hazards of an electric arc. The requirements do not address electric shock hazards nor the effects of noise, UV emissions, pressure shrapnel or toxic influences.
EN 1149: Electrostatic properties of protective clothing
Reduces the possibility of the clothing burning and thereby itself constituting hazard.
The protective clothing is intended to protect workers against occasional brief contact with small flames. The working circumstances offer no significant heat hazard and there is no presence of another type of heat.
- Requirements for limited flame spread index 1
The flame does not spread, there are no flaming debris, no afterglow, a hole may be formed.
- Requirements for limited flame spread index 2
The flame does not spread, there are no flaming debris, no afterglow, no hole formation.
- Requirements for limited flame spread index 3
The flame does not spread, there are no flaming debris, no afterglow, no hole formation, the afterflame times of each individual specimen is less than 2 seconds.
EN ISO 11612: Protective clothing against heat and flame
The standards specifies the performance requirements for garments which protect the body from heat and flame (except the hands).
The following parameters are used:
- Requirements for parameter A
Minimum requirement, fabric combination
- Requirements for parameter B(B1>B5)
Insulation against convective heat
- Requirements for parameter C(C1>C4)
Insulation against radiant heat.
- Requirements for parameter D(D1>D3)
Insulation against molten aluminum
- Requirements for parameter E(E1>E3)
Insulation against molten cast iron
EN ISO 11611: Protective clothing for use in welding and allied process
The protective clothing is intended to protect the wearer against small splashes of molten material, short contact time with flame, radiant heat from ARC, the clothing minimizes the possibility of electrical shock by short accident contact with live electrical conductors up to 100V DC.
The standard specifies 2 classes with specific performance requirements:
- Class 1 – lower level:
Less hazardous welding situations
- Class 2 – higher level:
More hazardous welding situations
EN 13034: Protective clothing against liquid chemicals – Limited protective performance
EN 13034 covers the lowest level of chemical protection intended to protect from a potential exposure to small quantities of spray or accidental low volumes splashes of less hazardous chemicals against which a complete liquid permeation barrier (at a molecular level) is not required.
- Type 6
Type 6 suits protect at least the trunk and limbs (e.g. one-piece coveralls or two piece suits)
- Type PB(6)
Partial body protection Type PB(6) cover and protect only specific parts of the body (e.g. Jackets, aprons, etc)
