Industry Standard Updates

Released end of May 2020


CEN/TC127 have been working on the new version of the SBI standard (EN 13823) which was released at the end of May 2020. In this new version of the standard the bi-directional probe in the exhaust duct, used for measuring the exhaust flow rate, needs to be replaced with a hemispherical probe.


All labs need to replace the bi-directional probe with a hemispherical probe and change the probe constant (kp) value in their software (from 1.08 to 1.24) in order to remain complaint.


A new hemispherical probe can be purchased from FTT. When replacing the probe a new set of commissioning tests will need to be performed, a service which the FTT Support Team are able to provide.
