ASTM D4309-12

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D4309 − 02 (Reapproved 2007) D4309 − 12
Standard Practice for
Sample Digestion Using Closed Vessel Microwave Heating
1
Technique for the Determination of Total Metals in Water
This standard is issued under the fixed designation D4309; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This practice covers the general considerations for quantitative sample digestion for total metals in water using closed vessel
microwave heating technique. This practice is applicable to surface, saline, domestic, and industrial wastewater.
1.2 Because of the differences among various makes and models of satisfactory instruments, no detailed operating instructions
can be provided. Instead, the analyst should follow the instructions provided by the manufacturer of the particular instrument.
1.3 This practice can be used with the following ASTM standards, providing the user determines precision and bias based on
this digestion practice: Test MethodsMethod D857, Test Methods D858, Test Methods D1068, Specification D1192, Test Methods
D1687, Test Methods D1688, Test Methods D1691, Test Methods D1886, Test Method D1976, Practices D3370, Test Methods
D3557, Test Methods D3559, Practice D3919, Test MethodsMethod D4190, Practice D4453, and Practice D4691, and Test Method
D5673.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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. For specific hazard statements, see Section 9.
