Description of the programme


This interlaboratory comparison (AGLAE's programme ‘4Eb’) in waste waters similar to industrial waste waters is provided in the frame of:

  • accreditation scopes related to physico-chemical analyses in waters (check AGLAE's accreditation - Cofrac No. 1-1664)

  • approvals issued by Departments of environment

This proficiency testing is identical to the test 'VOHs and benzene derviratives in waste waters’ but at lower concentration levels to meet specific requirements.
