CEN/TC 162/WG 13 - Joint Working Group between CEN/TC 162 and CEN/TC 161 - Test methods for permeation of chemicals through materials for protective footwear, gloves and clothing

This European Standard specifies a test method for the determination of the resistance of protective
clothing, gloves and footwear materials to permeation by potentially hazardous gaseous chemicals
under the condition of continuous contact.
This test method is applicable to the assessment of protection against gazeous chemicals that can be
collected only by liquid or gaseous collecting media.
!This test method is not applicable for the assessment of gaseous chemical mixtures."
This test method describes the modifications to EN 16523-1 necessary to test against gaseous chemicals
that can be collected by liquid or gaseous collecting media.

This European Standard specifies a test method for the determination of the resistance of protective clothing, gloves and footwear materials to permeation by potential hazardous liquid chemicals under the condition of continuous contact.
This test method is applicable to the assessment of protection against liquid chemicals that can be collected only by liquid or gaseous collecting media.
This test method is not adapted for the assessment of chemical mixtures, except for aqueous solutions.
This standard shall be used with the specifications given in the products standards (for examples EN 374 1 for gloves) where the following information shall be defined:
-   any pre-conditioning;
-   precise sampling (place, size, number);
-   associated levels of performance.

ISO 19918 describes laboratory test methods to determine the resistance of materials, closures, and seams used in personal protective equipment (PPE) to permeation by solid or liquid chemicals with low vapour pressure (less than 133,322 Pa at 25 °C) and/or insolubility in water or other liquids commonly used as collection media. 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 low solubility in commonly used liquid and gaseous collection media.
This test method is not intended to be used in place of standards such as ISO 6529, EN 16523-1 and ASTM F739, which measure permeation of chemicals that are either volatile or soluble in water or other liquids that do not interact with the material being tested. ISO 19918 is not suitable for measurement of volatile chemicals that may evaporate before the chemical analysis is complete.
The degree of contamination depends on numerous factors, such as type of exposure, application technique, and chemical 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 may be used for the evaluation of PPE materials that are new or those for which the product standard requires treatment, such as laundering or simulated abrasion. Details of the treatment shall be reported.
