Information for 2025
New:Registration for the proficiency test rounds as well as the transmission of results for IFA proficiency test rounds are carried out via the web application “ifatesten“.
You can freely choose, in which PT rounds you would like to participate and how many parameters you are going to determine.
In order to ensure that the proficiency tests from the cooperation partner (UBA) are evaluated with statistical relevance, at least 15 participants are required. Therefore, rounds with fewer registrations have to be cancelled.
In 2025 our cooperation partner (UBA) will not organize a proficiency test round for pesticides in accordance with the Drinking Water Ordinance (PM). PM06 is expected to implemented in 2026.
In round N175 (major ions) the Environment Agency Austria will provide Ntot and pH as additional parameters.
In rounds N176 and N178 (major ions) the IFA Tulln will provide silicon and fluoride as additional parameters.
In rounds N177 and N179 (major ions) the IFA Tulln will provide KMnO4-Index as an additional parameter.
In round N178 (major ions) the IFA Tulln will provide easily liberatable cyanide as an additional parameter.
In round M177 (metals and trace elements), in addition to the usual scope, the parameters beryllium, cerium, cobalt, gadolinium, lithium, silver and vanadium will be included.
In round M179 (metals and trace elements), in addition to the usual scope, the parameters antimony, barium, molybdenum, strontium and tin will be included. Exceptionally, mercury is not included in this round.
In round CB12 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.
The proficiency tests VHH and BTEX&MTBE in real water samples (UBA) will be offered in an alternation mode.
In 2025 BTEX & MTBE are offered and a proficiency test for VHH for real water samples will take place in 2026.
In round SP10 (sum parameters) the Environment Agency Austria offers the combination of hydrocarbon oil index and phenol index.
It is also possible to select only the hydrocarbon oil index; only phenol index cannot be selected. Evaluation of the round will be carried out in a joint report.
