Annex ZA (informative) - Relationship between this European
Standard and the essential requirements of EU Directive
89/686/EEC aimed to be covered
Defines 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 Degree C) and/or insolubility in water or other liquids commonly used as collection media.
