EN 1149 is a series of European standards related to anti-static properties. These standards aim to standardize the electrical performance requirements and test methods for materials used in anti-static protective clothing to ensure that the protective clothing can effectively dissipate static electricity and protect the safety of the wearer and the surrounding environment. These standards are important in industries involving flammable materials, electronic components, or other areas that are sensitive to static electricity. Next, we will detail each part of these standards.

EN 1149-1: Surface resistance test method

EN 1149-1 specifies a method for testing the surface resistance of protective clothing materials. This test evaluates a material's ability to dissipate static electricity by measuring its surface resistance. Lower surface resistance means the material can dissipate static electricity more quickly, reducing sparking and other static risks.

EN 1149-2: Vertical resistance test method

EN 1149-2 describes a test method for measuring the vertical resistance of fabrics. This test evaluates a material's ability to conduct electricity in a vertical direction. This is crucial to determine the electrical properties of the material in different directions to ensure that protective clothing provides comprehensive electrostatic protection in practical applications.

EN 1149-3: Charge decay performance test method

EN 1149-3 specifies test methods for measuring the charge decay properties of materials. This test evaluates how quickly a material dissipates static electricity after being exposed to an electrical charge. This is crucial to ensure that protective clothing can effectively eliminate static electricity during use and reduce the risk of static electricity.

EN 1149-4: Performance requirements and test methods for protective clothing

EN 1149-4 focuses on performance requirements and test methods for protective clothing. This section describes the design, manufacturing, and testing requirements for protective clothing used to protect against static electricity. It ensures that the overall performance of protective clothing, including material selection, design and manufacturing processes, meets strict safety standards.

EN 1149-5: Protective clothing material performance requirements and test methods

EN 1149-5 specifies the performance requirements and test methods for materials with antistatic functions used in protective clothing. This standard ensures that the material can effectively dissipate static electricity and provide reliable protection when used.
