Information for 2021

  • You can freely choose, in which PT rounds you would like to participate and how many parameters you are going to determine.
  • At least 15 participants are required to ensure an evaluation of the ring tests with statistical relevance. Therefore, rounds with fewer registrations have to be cancelled.
  • In round N155 (major ions) the Umweltbundesamt GmbH will provide Ntot and pH as additional parameters.
  • In round N156 (major ions) the IFA Tulln will provide silicon and fluoride as additional parameters.
  • In round N157 and N159 (major ions) the IFA Tulln will provide KMnO4-Index as an additional parameter.
  • In round N158 (major ions) the IFA Tulln will provide easily liberatable cyanide as an additional parameter.
  • In round M157 (metals and trace elements) antimony, barium, cerium, cobalt, lithium, molybdenum, silver, tin and vanadium will be included.
  • In round CB08 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 SP06 (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, selection of phenol index only is not possible. Evaluation of the round will be carried out in a joint report.
