Description of the programme

This interlaboratory comparison (AGLAE's programme ‘1Ab’) 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 'Chemical analyses in clean waters' but at lower concentration levels to meet specific requirements.

List of parameters

pH, conductivity at 25°C, REDOX potential, degree of hardness, total alkalinity,
NH4+, NO2-, NO3-, Na+, Ca2+, K+, Cl-, SO42-, PO43-, SiO32-, KMnO4 index,
turbidity, total organic carbon (TOC), Mg2+, F- and the colour by comparison with hexachloroplatinate (without filtration)

‘Environment approval’: this is an additional proficiency test identical to the tests of programme 1A but at low concentration levels to meet the requirements of the French Order of 27/10/11 completed by the order of the 08/11/15 for the relevant parameters (as long as it is possible to maintain the quality of the test). Target concentration ranges available on request.
