ISO 14869-2:2002

Последний раз этот стандарт был пересмотрен в 2019. Поэтому данная версия остается актуальной

ISO 14869-2:2002 specifies a method for the dissolution of total contents for the following elements in soils:

Na, K, Mg, Ca, Ti, Mn, Fe, Al, Si

This list is not exhaustive, and other elements are applicable for determination provided:

where

w is the mass content of the element, expressed in milligrams per kilogram soil,

d is the detection limit, in milligrams per litre, for the element and analytical method considered,

3 is a conventional factor,

V is the adjusted volume, in litres, of the final solution containing the dissolved sample, and

m is the mass of the test portion, in kilograms,

the determination is not adversely affected by the high salt concentration in the resultant solution.

The flux proposed in this method is suitable for a wide range of materials, among which soil samples are relatively easy to deal with.
