Dear participants,

After 9 years, the program "Spark Ignition" has been closed. There are no more test samples available and it is only possible with disproportionate effort to create new test samples according to the old specifications, which meet the homogeneity requirements. 
With the programs "Intrinsic Safety" and "Battery Testing" there are still two programs available which refer to IEC 60079-11.

We thank all participants for the very good and fruitful cooperation in this program and look forward to new interesting programs in the future.

Kind regards,

Your Proficiency Testing Team
