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.

• EN 1149-2:1997

  EN 1149-2:1997 is a standard for electrical arc protection for protective clothing. It establishes performance requirements for materials and garments used in protective clothing to protect against electrical arcs. The standard includes tests for measuring the arc resistance, material flammability, and garment construction. Possible test results include pass/fail for each of these categories.

  Performance Tested

  The EN 1149-2:1997 standard is designed to assess the electrostatic properties of protective clothing, specifically measuring the electrical resistance through a material, referred to as vertical resistance. Evaluating the test result involves determining how well the protective fabric can prevent a build-up of static electricity, which is vital for safety in environments where electrical discharges could pose a fire or explosion risk. The test method includes applying a voltage across a fabric sample while it is sandwiched between two electrodes, and the resistance is measured at both high and low voltage levels to ensure accuracy. Businesses must consider this result when selecting protective clothing for environments with potential electrical hazards, ensuring that the material has adequate resistance to prevent static electricity build-up and provide a safeguard against electrostatic discharges in volatile work conditions.

• EN 1149-1:2006

  EN 1149-1:2006 is a European standard that specifies the requirements for electrostatic discharge (ESD) protective clothing. The standard defines the performance requirements for material, design, and testing of ESD clothing. The clothing must be able to effectively discharge static electricity and protect the wearer from ESD. Testing includes measuring the surface resistance and charge decay of the clothing material. Pass/fail results are based on the clothing meeting or not meeting the specified requirements.

  Surface Resistance Tested

  The standard EN 1149-1:2006 specifies the methodology to measure surface resistance in order to assess the electrostatic properties of materials, typically used for protective clothing. A result specifying surface resistance under this standard means the material has been assessed for its ability to dissipate electrostatic charges, which is crucial in environments where electrostatic discharges can be hazardous. The test involves measuring the resistance of the material surface using electrodes to determine if the resistance value is less than 2.5 × 10(9) ohms, which is the threshold for compliance. This threshold ensures that the material can effectively dissipate electrostatic charges, thereby enhancing safety in electrostatic-sensitive environments. For procurement professionals, understanding that a product meets this standard indicates suitability for use in applications where electrostatic discharge poses a risk, such as in electronic assembly or explosive atmospheres.
