Description of the programme

This interlaboratory comparison (AGLAE's programme ‘4C’) in tap water, surface waters or bottled waters is provided in the frame of:
  • accreditation scopes related to physico-chemical analyses in drinking waters (check AGLAE's accreditation - Cofrac No. 1-1664)
  • approvals issued by Departments of environment or Ministries of Health
An identical proficiency test is also conducted at lower concentration levels to meet specific requirements.
