Standards and labels

• EN 1149-3:2004

  EN 1149-3:2004 is a European standard that specifies the requirements for electrostatic dissipative (ESD) footwear. The standard defines performance requirements for material, design, and testing of ESD footwear. The footwear must be able to effectively discharge static electricity and protect the wearer from ESD. Testing includes measuring the surface resistance of the footwear material. Pass/fail results are based on the footwear meeting or not meeting the specified requirements.

  Electrostatic Properties Tested

  The EN 1149-3:2004 standard specifies the test method for assessing the electrostatic properties of materials, specifically their ability to dissipate an electrostatic charge. The crucial test result for the standard is that a material must have a half decay time of less than 4 seconds or a shielding factor greater than 0.2 to meet the criteria stipulated by EN1149-5. This is determined through a testing process where a specimen is subjected to an induction effect that charges the material. Its ability to dissipate this charge is then measured by recording the decrease in field charge observed by a probe positioned above the test surface. The practical implications of this result for materials, especially in safety and protective clothing, are significant as it ensures that the material can quickly neutralize electrostatic charges, reducing the risk of discharge sparks in environments where flammable or explosive gases may be present.
