EN 1149-5:IS A FAMILY OF STANDARDS AND INCLUDES 5 PRIMARY TEST METHODS PLEASE NOTE - EN 1149-4: Garment Test (Is under development). The other test method are described below. WHAT IS EN 1149-5? 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. EN 1149

EN 1149-1: 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.

EN 1149-2: 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.

EN1149-3: 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.
