Phase Out of Acknowledgement Letters

ISTA’s Global Board of Directors routinely assesses all aspects of the Association to ensure resources are leveraged in an effective manner that maximizes benefit to members while ensuring long term-viability.   Upon recent assessment, the decision was made to discontinue the issuance of testing acknowledgement letters for test reports submitted to ISTA Headquarters by ISTA certified labs for non-members and focus these resources towards other ISTA programs.  Acknowledgement letters will no longer be provided after August 1, 2020.

Please contact Eric Hiser, ISTA Vice President of Technical with any questions.
