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 European Standard is not applicable for specifying protection against main voltages.
Test method for measurement of surface resistivity. Surface resistance measures the conductivity between two points on the surface of a fabric. The lower the resistance the higher the conductivity, resulting in charge going to earth.
Test method for measurement of the electrical resistance through a material (vertical resistance). This is the level of conductivity when measured through the depth of a fabric.
Test methods for measurement of charge decay. Charge decay measures how long it takes for an electric current to dissipate. The quicker it dissipates the higher the anti-static properties of the garment.
Please note the EN 1149-4 Garment Test is under development.
EN 1149-5 specifies the performance and design requirements to avoid static discharge for all electrostatic dissipative protective clothing as part of an entire earthed system, shoes, clothing & floor. The material meets the requirements.
