Dear participants,

I am pleased to inform you that the interim report of the program "Flame Transmission - Test Round 2013" is available for download now.

You will find the report after login on our website (http://www.ex-proficiency-testing.ptb.de) under section:

Programs -->  Program 3 "Flame Transmission"--> Download

Please be aware that the individual data and results are not ready for further publication. This stage will be achieved later this year after intensive discussion within our IECEx community. Therefore we seriously recommend to keep all results as internal and confidential material.

Now the phase II of program "Flame Transmission - Test Round 2013" starts. The participating laboratories will analyze their results compared with the other laboratories and are invited to repeat the tests after improvement of their procedures and instrumentation, if they are not happy with their position regarding the difference with the assigned value. During this phase the participants are invited to individual and confidential discussion of their results with PTB experts. As far as our team could already identify any inconsistencies, this will be addressed in direct contact to the respective participants in the next days.

The phase II will end at

30th of May, 2014.

Until this date you need to upload your new data set made during phase II. If you do not want to take part in the phase II session, your data of the phase I will be used for the final report of the program "Flame Transmission - Test Round 2013" which will be published in June 2014.

I would like to thank you for your excellent cooperation and the trust placed in us.

If you have questions or concerns please let me know.

Kind regards

Tim
