Description of the programme

These interlaboratory comparisons (AGLAE's programme ‘2B’) in waste waters are 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

An identical proficiency testing is also conducted at lower concentration levels to meet specific requirements.
