Description of the programme

This interlaboratory comparison (AGLAE's programme ‘4Cb’) in tap water, surface waters or bottled 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 or Ministries of Health

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