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 1149:2018 - Protective Clothing - Electrostatic Properties - Part 5. Material Performance and Design Requirements.
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.
