Development of Audit Devices and Materials for Source Level Air Pollution Measurement Methods

摘要

The paper describes the procedures followed by the U.S. Environmental Protection Agency (EPA), Quality Assurance Division, when developing a source level audit device or material (d/m). The audit d/m's are used to quantitatively determine that an EPA reference method is being properly performed by an analyst. The procedure to develop and audit d/m is described by discussing the development of an audit material for EPA reference Method 5, Determination of Particulate Emissions from Stationary Sources. The paper also presents a list of all audit d/m's currently available from the EPA Quality Assurance Division.
