Dear participants,

I am pleased to inform you that the draft final report of program "Intrinsic Safety - Test Round 2015" is available for download now.

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.

Due to characteristic of the program “IS”, there is no Phase II which mentioned as improvement phase usually. Please notice that in the draft final report are the first comments, which are specified only with PTB expert group. After the workshop and further discussion with the participants, the conclusion in the report could be updated and the final report will be released at the beginning of August 2016.

For participants who will not join the PT Workshop 2016, PTB always offers individual support for discussion of the test records. Therefore, if you have any concerns about the item(s) in your test record, please contact PTB directly up to

31^th of July 2016.

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,

Jia Wu
