EPA Method 9 Visual Determination of Opacity for Stack Emissions: Laboratory Testing Services by Eurolab

1.1 Introduction to EPA Method 9

The Environmental Protection Agencys (EPA) Method 9 is a widely accepted standard for determining the opacity of stack emissions. Opacity refers to the degree to which light is obscured by particles or gases emitted from a source, such as an industrial facility or power plant. The method involves visual observation and measurement of the optical density of emissions using a trained observer.

1.2 Relevant Standards and Regulations

  • ISO 11600:2015: International Organization for Standardization (ISO) standard for determining the opacity of stack gases.
  • ASTM E96-15: American Society for Testing and Materials (ASTM) standard for determining the opacity of stack emissions.
  • EN 14181:2004: European Committee for Standardization (CEN) standard for determining the opacity of stack gases.
  • 1.3 International and National Standards

    The following standards apply to EPA Method 9:

    Region/Country Standard Number

    --- ---

    USA EPA Method 9

    Canada CAN/CSA-C255-08

    Europe EN 14181:2004

    1.4 Standard Development Organizations

  • ISO: The International Organization for Standardization (ISO) is an independent, non-governmental organization that develops and publishes international standards.
  • ASTM: The American Society for Testing and Materials (ASTM) is a voluntary standards development organization that develops and publishes technical standards.
  • 1.5 Evolution of Standards

    Standards evolve over time as new technologies emerge and existing ones are refined. Regulatory agencies, such as the EPA, play a crucial role in updating standards to reflect changing requirements.
