Annotation of standard text ČSN P CEN/TS 17701-2 (655002):

This document specifies a method for the determination of arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), nickel (Ni) and zinc (Zn) in plant biostimulant digests using inductively coupled plasma-atomic emission spectrometry (ICP-AES).
This document is also applicable to the blends of fertilizing products where plant biostimulants are the main part of the blend. Otherwise, the Technical Specification for the main part of the blend applies.
This method is applicable to aqua regia digests prepared according to CEN/TS 17701-1. The method can be used for the determination of other elements, provided the user has verified the applicability
