Date Posted: 11-27-2012
On August 1, 2012, the NELAP Accreditation Council adopted into the program changes to the accreditation requirements for proficiency testing for laboratories that perform Whole Effluent Toxicity testing. These changes were approved by the Proficiency Testing Expert Committee on April 12, 2012 and a summary of the changes can be found here: http://www.nelac-institute.org/docs/standards/2012/TIA-PT/WET TIA_11 03 09 revised4-4-12-12.pdf
