EN 374-3 Protective Gloves Chemical Permeation Testing
The European Standard EN 374-3 is a crucial guideline used globally for testing protective gloves against chemical permeation. This standard ensures that workers are adequately protected when handling hazardous chemicals in various sectors such as pharmaceuticals, manufacturing, and chemical processing.
Protective gloves designed to meet the requirements of EN 374-3 must demonstrate resistance to penetration by specific chemicals under defined conditions. The test involves exposing gloves to a series of chemicals for a set period, followed by evaluating the glove for any signs of permeation or deterioration. This process ensures that the gloves can effectively shield the wearer from chemical exposure.
The standard applies to all types of protective gloves intended for use in environments where there is a risk of chemical contact. It evaluates both the physical integrity and the barrier properties of these gloves against chemicals, providing a comprehensive assessment of their safety performance.
It's essential to note that EN 374-3 specifies three classes of chemical resistance: Class I, II, and III. Each class corresponds to different levels of permeation resistance. Gloves must pass the required test for each chemical they claim to protect against. This classification ensures that workers are provided with gloves suitable for the specific chemicals they may encounter.
The testing procedure involves placing a sample glove in contact with a defined volume of liquid chemical for a specified duration. The chemical is then withdrawn, and any permeation through the glove is evaluated visually or by other means as outlined in the standard.
For accurate and reliable results, it's critical to follow all prescribed steps meticulously. This includes precise control over temperature, humidity, and exposure time, which can significantly influence the outcome of the test. Compliance with these conditions ensures that the testing accurately reflects real-world usage scenarios.
In addition to ensuring worker safety, compliance with EN 374-3 is often a legal requirement in many countries. This standard helps employers meet occupational health and safety regulations, thereby reducing the risk of chemical-related accidents and injuries in the workplace.
The importance of this test cannot be overstated, especially for industries where workers may come into contact with aggressive chemicals that could cause severe burns or other hazards if not properly protected. By adhering to EN 374-3, companies can demonstrate their commitment to worker safety and regulatory compliance.
