Description of the programme

This interlaboratory comparison (AGLAE's programme ‘2C’) in waste waters is provided in the frame of:

  • accreditation scopes related to physico-chemical analyses of waters (check AGLAE's accreditation Cofrac No. 1-1664)
  • approvals issued by Departments of environment

This proficiency testing is identical to the test 'Indicators in waste waters' but at lower concentration levels to meet specific requirements.
