EN ISO 11612: 2008 - Protective Clothing Against Heat and Flame
The Performance requirements set out in this international standard are applicable to garment, which could be worn for a wide range of end uses, where the is a need for clothing with limited flame spread properties and where the used can be exposed to radiant, convective or contact heat or molton metal splashes.
This test uses standard methods and conditions to predict the performance of fabric/garment in the event of contact with heat or flames. Garment features such as seams, closures and logos must be tested as well as the fabric. Tests must be carried out on pre=treated components according to the manufacturers care label.
Specific Testing is listed below:
- Dimensional Charge
- Limited Flame Spread (A1+A2)*
- Convective Heat (B) – 3 Levels
- Radiant Heat (C) - 4 Levels
- Molten Aluminium Splash (D) – 3 Levels
- Molten Iron Splash E - 3 Levels
- Contact Heat (F) – 3 Levels (Temp 250 Degrees Celcius)
- Heat Resistance at a temperature of 180 Degrees Celcius
- Tensile Strength Must meet a minimum of 300N
- Tear Strength must meet a minimum of 15N
- Bursting Strength
- Seam Strength
Garment Design requires that coverage must be provided from the neck to the wrist and to the ankles.
Optional Testing includes water vapour resistance and manikin testing for overall burn prediction.
*This test must be carried out on fabric and seams.
EN ISO 11611: 2007 - Protective Clothing for Use in Welding and Allied Processes
The International standard specifies minimum basic safety requirements and test methods for protective clothing for use in welding and allied processes (Excluding Hand Protection).
The International Standard Specifies two classes with specific performance requirements:
Class 1 is protection against less hazardous welding techniques and situations causing lower levels of spatter and radiant heat.
Class 2 is protection against more hazardous welding techniques and situations causing higher levels of spatter and radiant heat.
EN ISO 11611 requires that protective suits completely cover the upper and lower torso, neck, arms and legs. There are a number of other design requirements which must be followed to prevent molten droplets lodging anywhere on the garment.
Testing must be carried out on pre-treated components according to the manufacturers care label.
- Tensile Strength (must meet a minimum of 400N)
- Tear Strength (Must meet a minimum of 20N)
- Bursting Strength
- Seam Strength
- Dimensional Charge
- Requirements of Leather
- Limited Flame Spread (A1+A2)*
- Molten Droplets
- Heat Transfer (Radiation)
- Electrical Resistance
*This test must be carried out on the fabric and seams.
EN1149 - 5 - Protective Clothing against the Thermal Hazards of an Electric Arc
This European Standard is part of a series of standards for test methods and requirements for electrostatic properties of protective clothing. The standard specifies material and design requirements for garments used as part of a total earthed system, to avoid incendiary discharges. The requirements may not be sufficient in oxygen enriched flammable atmospheres. This standard is not applicable for protection against mains voltages.
EN 1149 consists of the following parts:
EN 1149-1: Test Method for measurement of surface resistivty.
EN 1149-2: Test Method for measurement of the electrical resistance through a material (Vertical resistance)
EN 1149-3: Test Methods for measurement of charge decay.
EN 1149-4: Garment Test (under development)
EN 1149-5: Material Performance and design requirements.
Electrostatics dissipative protective clothing shall be able to permanently cover all non-complying materials during normal use. Conductives parts (Zips, Buttons etc) are permitted provided they are cover by the outermost material when in use.
EN ISO 20471 - High Visibility Clothing
This International Standard Specifies requirements for high visibility clothing, which is capable of visually signalling the user’s presence. The high visibility clothing is intended to provide conspicuity of the wearer in any light condition when viewed by the operators of vehicles or other mechanised equipment during daylight conditions and under illumination of headlights in the dark.
High Visibility clothing has a fluorescent surface, combined with reflective material that meets certification requirements in 3 different classes:
Class 3 - Highest Level
Required for any persons working on or near motorways/dual carriageways or airports. Must incorporate a minimum of 0.80m sq of background materials and 0.20m sq of retro-reflective materials. (4 metres of 5cm wide reflective tape)
Class 2 - Intermediate Level
Required for any person working on or near A and B Roads, also for delivery drivers. Must incorporate a minimum of 0.50m sq of background material and 0.13m sq of retro-reflective material. (2.60 metres of 5cm wide reflective tape)
Class 1 - Minimum Level
Minimum level of protection required for any persons working on a private road or to be sed in conjunction with a higher classed garment. Must incorporate a minimum of 0.14m sq of background material and 0.10m sq of retro-reflective material. (2 metres of 5cm wide reflective tape)
