| Nosaukums | This international standard describes laboratory test methods to determine the resistance of materials and seams used in protective clothing, including gloves, to permeation by liquids with low vapour pressure (less than 1 mm Hg at 25°C) and/or insolubility in water or another liquid that does not interact with the material. These chemicals that are often part of pesticide formulations and other mixtures cannot be measured using other standards for measuring permeation. This test method is suitable for field strength and concentrated pesticide formulations as well as other mixtures in which the active ingredient is a chemical with low vapour pressure and/or insolubility in water or another liquid that does not interact with the clothing material. This method may not be suitable for testing protective clothing materials against volatile pesticide formulations. The degree of contamination depends on numerous factors such as type of exposure, application technique, and pesticide formulation. As the level of exposure can vary considerably, this method is designed to rate relative performance of PPE materials for different durations. This method is designed to measure cumulative permeation. Breakthrough time cannot be measured by this method. This test method does not measure resistance to penetration or degradation. The test method standard can be used for the evaluation of materials that are new or those that have undergone treatment, such as laundering or simulated abrasion. Details of the treatment shall be reported. This test method can also be used to determine the resistance provided by protective clothing materials against permeation of chemicals with low vapour pressure. |
