标准范围

This part of ISO 14388 provides a general introduction to acid sulfate soils and the approaches that canbe used to measure the various components of this special group of soils and their potential to produceacidity. It provides a compilation of the test methods, identification and definitions of the symbols, terms,and acronyms used in this series of ISO 14388. While part of the decision-making process can involvethe analysis of prepared wet or dry samples, this part of ISO 14388 specifically outlines the proceduresthat are involved for preparing and analysing dried samples (see Figure 1).This part of ISO 14388 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 thehandling 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.This part of ISO 14388 provides an acid-base accounting method to calculate the net acid-producingpotential of acid sulfate soil materials by individually assessing the acid-producing capacity due tooxidation of inorganic sulfides, the existing acidity, and the effective acid-consuming capacity usingresults obtained in ISO 14388-2 and ISO 14388-3.
