Dear participants,

I am pleased to inform you that the final report of program "Temperature Classification - 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 4 "Temperature Classification"--> 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.

The participants are invited to individual and confidential discussion of their results with PTB experts. We will inform you about the next steps of the PTB Ex Proficiency Testing Scheme. It is intended to develop a general paper as a result of the analysis of the results and the experience of the whole program. This paper, in discussion with the community, should be a suggestion for best practice in tests for temperature classification in compliance with ISO 60079-0.

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

Kind regards,

Lisa
