Water quality. Digestion for the determination of selected elements in water - Nitric acid digestion PAS 15 commercial vehicles and motorcycles1 Scope This part of ISO 15587 specifies a method for extracting trace elements from a water sample using nitric acid as a digestion agent. The method is applicable to all types of waters with a suspended solids concentration of less than 20 g l and a total organic carbon (TOC) concentration expressed as carbon of less than 5 g l. The nitric acid digestion method is empirical and it might not necessarily release elements completely. However, for most
