Description of the programme


These interlaboratory comparisons (AGLAE's programme ‘1A’) in clear freshwaters, public drinking waters, spring waters and non-atypical natural mineral waters are 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 testing is also conducted at lower concentration levels to meet specific requirements.
