Information for 2019

  • Interlaboratory comparisons with natural samples (ground, surface, waste or drinking water, partly spiked) will be on offer covering all parameters, except VHH. This service is made possible by the cooperation between IFA-Tulln and the Umweltbundesamt GmbH's accredited testing laboratory for environmental, GMO & fuel analysis. Samples for VHH in real water samples will be performed in 2020.
  • In order to facilitate calculation of the target values with statistical relevance for interlaboratory comparisons with natural water, a minimum number of 15 participants is necessary. Otherwise, we reserve the right to refuse the realisation of the concerning round.
  • With the beginning of 2019 the unit for the parameter hardness will be changed to mmol/L instead of the german unit °dH in all rounds of major ions.
  • In round N145 (major ions) the Umweltbundesamt GmbH will provide Ntot and pH as additional parameters.
  • In round N146 (major ions) the IFA Tulln will provide silicon and fluoride as additional parameters.
  • In round N147 and N149 (major ions) the IFA Tulln will provide KMnO4-Index as an additional parameter.
  • In round N148 (major ions) the IFA Tulln will provide easily liberatable cyanide as an additional parameter.
  • In round M147 (metals and trace elements) antimony, barium, cerium, cobalt, lithium, molybdenum, silver, tin and vanadium will be included.
  • In round CB06 the IFA Tulln offers the combination of the parameter groups VHH and BTEX&MTBE in the same interlaboratory comparison. The extent of participation is selectable (VHH, BTEX&MTBE or both). Evaluation of the round will be carried out in a joint report.
  • In round SP04 (sum parameters) the Umweltbundesamt GmbH offers the combination of hydrocarbon oil index and phenol index.
    It is also possible to select only the hydrocarbon oil index. Evaluation of the round will be carried out in a joint report.
  • Z-Score-criteria for synthetic samples of IFA for the year 2019 will be recalculated on the basis of all IFA interlaboratory comparisons organised between 2008 and 2018 by the end of the year 2018.
