ASTM D6784-16

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: D6784 − 02 (Reapproved 2008) D6784 − 16
Standard Test Method for
Elemental, Oxidized, Particle-Bound and Total Mercury in
Flue Gas Generated from Coal-Fired Stationary Sources
1
(Ontario Hydro Method)
This standard is issued under the fixed designation D6784; 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
1.1 This test method applies to the determination of elemental, oxidized, particle-bound, and total mercury emissions from
coal-fired stationary sources.
1.2 This test method is applicable to elemental, oxidized, particle-bound, and total mercury concentrations ranging from
3
approximately 0.5 to 100 μg/Nm .
1.3 This test method describes equipment and procedures for obtaining samples from effluent ducts and stacks, equipment and
procedures for laboratory analysis, and procedures for calculating results.
1.4 This test method is applicable for sampling elemental, oxidized, and particle-bound mercury in flue gases of coal-fired
stationary sources. It may not be suitable at all measurement locations, particularly those with high particulate loadings, as
explained in Section 16.
1.5 Method applicability is limited to flue gas stream temperatures within the thermal stability range of the sampling probe and
filter components.
1.6 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.7 This standard assumesrequires users are to be familiar with EPA stack-gas sampling procedures as stated in EPA Methods
1–4, Method 5, and Method 17.
1.8 The method requires a high level of experience and quality control both in the field testing and analytical procedures in order
to obtain high quality data.
1.9 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.
