Soil quality -- Acid-base accounting procedure for acid sulfate soils -- Part 1: Introduction and definitions, symbols and acronyms, sampling and sample preparation
Product Details
ISO 14388-1:2014 also provides a procedure for pre-treating acid sulfate soil following sampling, prior to their analysis as dried sample using appropriate methods of test. The procedure includes the handling of samples before delivery to the laboratory, and the drying, grinding, and storage of samples. The standard also provides a procedure for archiving a sample after analysis.
ISO 14388-1:2014 provides an acid-base accounting method to calculate the net acid-producing potential of acid sulfate soil materials by individually assessing the acid-producing capacity due to oxidation of inorganic sulfides, the existing acidity, and the effective acid-consuming capacity using results obtained in ISO 14388-2 and ISO 14388-3.
