Information about the current Needle/Leaf Interlaboratory Test
For future tests I always need dried and powdered foliage samples from one tree and one "leaf type" or needle set (dry weight approx. 4-5kg leaves or needles) or a homogenized litterfall sample (dry weight approx. 4-5kg). If someone is willing to do this sampling and preparation work for one of the next ringtests*), please contact me by e-mail.

Timetable for the 16th Interlaboratory Test 2013/2014

Informing the participating labs via email (March/April 2013)
Registration of the participants via internet (Deadline July 15th, 2013)
Distribution of four test samples with an invoice for the participation fee (August 2013)
Payment must be done before data submission!
Data submission by the labs (October-December 2013)
Deadline of data submission (Deadline January 1st, 2014)
First results (January 2014)
Re-qualification process started (see requalification process details)
Final Report and online Qualification Report (January/February 2014)
Re-qualification process finished (Deadline October 1st, 2014)

All four samples (two spruce, one ash and one pine samples) were prepared from BFW/Austria, many thanks to Walter Wuggenig/Austria and his employees for collecting two samples.

For each parameter (total element concentration) four replicates are necessary for this Interlaboratory Test. The results for the elements S, N. P, K, Ca, Mg, C, Zn, Mn, Fe, Cu, Pb, Cd and B will be evaluated. Mandatory parameters are S, N, P, K, Ca, Mg and C! Other additional elements can be analysed, but only the results will be given in the report, without detailed statistical evaluation. An overview of the elements that can be analysed and the proper units for all elements are avalable here. Don't forget to use only  recommended methods which are described in the ICP-Forests submanual Sampling and Analysis of Needles and Leaves. The recommanded minimum sample weight is 250 mg. All results must be calculated on dry weight (105°C).

Data submission and confirmation of the results must be done by the participating laboratories on their own over the internet with a web-based interface to an Oracle database. If your laboratory is analysing foliar/litterfall samples for the ICP-Forests Programme on Level II, the interlaboratory test samples should be analysed within this sample batch, but they must be finished before the deadline.

Together with the ringtest report each participant will have access to their online qualification report. Re-qualification is mandatory for all ICP-Forests laboratories. In this ringtest laboratory code-numbers will be opened to all participants, the working group QA/QC in labs, ICP-Forests and to the Members of Expert Panel Foliage and Litterfall.

Some words about the costs - all participants had to pay a participation fee of 190 Euros. You will get the debit note with the test samples and the payment of the participation fee must be done before data submission (Data submission page will be opened after we received your participation fee!). Please, indicate the debit number and the laboratory-code number on the transfer order! If somebody really has problems to pay this fee - please, contact me - I will try to find a solution for this laboratory.

Don't forget - if there are changes in responsible person, name, address, phone number and the e-mail address - to correct this information in the database (see Addresses of the labs). For further information about the current ringtest it is important for me to have your correct address.

New participants should send me an e-mail, they will be informed in time about the next Foliar Interlaboratory Comparison Test.
