ASTM E1726-95
Historical Standard: ASTM E1726-95 Standard Practice for Preparation of Soil Samples by Hotplate Digestion for Subsequent Lead Analysis
SUPERSEDED (see Active link, below)
ASTM E1726
1. Scope
1.1 This practice covers drying, homogenization, and acid digestion of soil samples and associated quality control (QC) samples using a hot plate type method for the determination of lead using laboratory atomic spectrometry analysis techniques such as Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES), Flame Atomic Absorption Spectrometry (FAAS), and Graphite Furnace Atomic Absorption Spectrometry (GFAAS).
1.2 This practice is based on U.S. EPA SW846 Method 3050.
1.3 This practice contains notes that are explanatory and are not part of the mandatory requirements of this standard.
1.4 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
