Description of the programme

This interlaboratory comparison (AGLAE's programme ‘4C’) in public drinking waters, spring waters and non-atypical natural mineral 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.

For BTEX and VOC in non-atypical mineral waters, check the dedicated programme BTEX and VOC in atypical and non-atypical natural mineral waters.
