Standard Test Method for Sampling and Determining Particulate Matter in Stack Gases Using an In-Stack, Inertial Microbalance

Importancia y uso:

5.1 The measurement of particulate matter is widely performed to characterize emissions from stationary sources in terms of emission concentrations and emission rates to the atmosphere for engineering and regulatory purposes.

5.2 This test method provides near real-time measurement results and is particularly well suited for use in performance assessment and optimization of particulate matter controls achieved by air pollution control devices or process modifications (including fuel, feed, or process operational changes) and performance assessments of particulate matter continuous emissions monitoring systems (PM CEMS).

5.3 This test method is well suited for measurement of particulate matter-laden gas streams in the range of 0.2 mg/m³ to 50 mg/m³, especially at low concentrations.

5.4 The U.S. EPA has concurred that this test method has been demonstrated to meet the Method 301 bias4 and precision criteria for measuring particulate matter from coal fired utility boilers when compared with EPA Method 17 and Method 5 (40 CFR 60, Appendix A).

5.5 This test method can accurately measure relative particulate matter concentrations over short intervals and can be used to assess the uniformity of particulate concentrations at various points on a measurement traverse within a duct or stack.
