Organization: ASTM
Publication Date: 8 September 1967
Status: inactive
Page Count: 4
scope:

(a) The purpose of these recommended practices is to guide in establishing or adopting sampling and sample preparation procedures that are, in turn, aids to obtaining reliable, accurate spectrochemical results. A primary concept of spectrochemical analysis, as related to sampling and sample preparation, is first discussed. This is followed by a discussion of the factors that should be considered in selecting sampling and sample preparation procedures.

(b) The practices are concerned with procedures of spectrochemical analysis, including optical emission, X-ray, flame, and atomic absorption; however, the general principles are applicable to other analytical methods. For simplicity, all samples are classified as bulk solids, powders, or liquids; gases have not been included. The practices generally cover sampling procedures and sample preparation techniques for most types of substances or materials that are analyzed by spectrochemical means; however, highly specialized techniques for materials that are radioactive, pyrophoric, toxic, etc., have not been included. Although some general recommendations are made about "primary" sampling procedures that pertain to a large amount of a substance, the practices mainly are concerned with "secondary" sampling procedures and sample preparation techniques that are essential to obtain representative spectrochemical results from the laboratory sample.
