BS ISO 14869-2:2002

This standard BS ISO 14869-2:2002 Soil quality. Dissolution for the determination of total element content is classified in these ICS categories:

• 13.080.10 Chemical characteristics of soils

This part of ISO 14869 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

• they are not lost during the fusion process,

• w > (3 d · V/m)

  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.
