As part of the A2LA exclusive partnership with the Stack Testing Accreditation Council, Inc. (STAC), A2LA offers assessments to the ASTM D7036-Standard Practice for Competence of Air Emission Testing Bodies (AETBs) for organizations in the stack testing industry.

AETBs may choose to be assessed to the ASTM D7036 Standard alone, or they may combine their assessment with an evaluation of their compliance to ISO/IEC 17025 and achieve ILAC-endorsed accredited status under the A2LA environmental field of testing. Additionally, AETBs may be eligible for the Field Sampling and Measurement Organization (FSMO) program, which accredits field testing organizations to the NELAC Institute's Field Sampling and Measurement Organization Volume 1 Standard.

Please visit our Environmental Testing Accreditation Program page or our Field Sampling and Measurement Organization (FSMO) Accreditation Program page for more information about pursuing accreditation within one or both of these additional programs.

AETB Assessment and Accreditation Options

Option A Requirements

• ISO/IEC 17025
• The NELAC Institute's Field Sampling and Measurement Organization (FSMO) Volume 1 Standard
• ASTM D7036

This option falls under the A2LA ILAC Mutual Recognition Arrangement (MRA) Scope of Recognition and offers global recognition to the AETB.

Option B Requirements

ISO/IEC 17025

• FSMO Volume 1 Standard

This option is also covered under the A2LA ILAC MRA Scope of Recognition.

Option C Requirements

• ASTM D7036 only.

This option is not covered under the ILAC MRA, but is accepted by the Stack Testing Accreditation Council. Please note that Option C (accreditation to ASTM D7036 only) does not meet the minimum requirements for accreditation through any TNI State NELAC Accreditation Body (e.g., LELAP, FL DoH, or MNELAP). One way to achieve secondary accreditation through a state (e.g., Louisiana LELAP) is via accreditation by A2LA to ISO/IEC 17025 and the FSMO V1 standard.
