The TNI Laboratory Accreditation Body Expert Committee (LAB) is providing for your review and comment the following documents:

  • a revision of the V2M1 Draft Standard that addresses all comments received in response to the original Draft Standard (download the revised Draft Standard by clicking here), and
  • an Excel file of all comments received in response to the Draft Standard V2M1. All submitter names and contact information have been removed for this publicly available version of the file, but where identifiable, submitters have been notified of the resolution of their comments (download the Excel file by clicking here).

The comment period will be open for ninety (90) calendar days, until June 28, 2023, in accordance with the Consensus Standards Development SOP 2-100, located at Please send your comments and proposed revised text to both Aaren Alger, Chair of LAB ([email protected]) and Lynn Bradley, Program Administrator for LAB ([email protected]). All comments will be tracked by Lynn and you will be notified of the committee’s response to your comment after all comments are considered and addressed if they are deemed persuasive.

Within this document, all ISO language is italicized and unchanged from the most recent (2017) version of ISO/IEC 17011. The TNI-added language is in plain text, with deletions struck through and new language underlined – changes showing are from the Draft Standard that was published in December 2020.

You are invited to provide comments on any portion of the Draft Standard, as you see fit. We do ask that you provide alternative wording that would address your concern whenever possible. As with prior revisions of TNI standards, all comments will be ruled either persuasive, non-persuasive, or editorial by the committee, and addressed accordingly. If substantive or controversial changes are required to this Draft Standard Revision 1, it will be re-presented for public comment at a later date, as Revision 2, but if there are no substantive or controversial changes required, the document will move towards final approval as the new Volume 2 Module 1 that will replace V2M1 and V2M3 in the next version of the complete TNI Environmental Laboratory Standard, whenever that document is issued.
