Proficiency test - chemistry

Description of the programme


These interlaboratory comparisons (AGLAE's programme ‘2D’) 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

 

 


List of parameters


Détail des paramètres mis en oeuvre

pH, conductivity, turbidity, REDOX potential, true colour by comparison with hexachloroplatinate

True colour analysed by spectrophotometry according to method C of the EN ISO 7887 standard. The determination of the true colour according to the method D of the EN ISO 7887 standard can be carried out; a statistical treatment of data obtained with this method may be considered if the number of results returned by the participants is sufficient
