Thickness Standards ISO16809 vs. EN14127

Can someone who was paying more attention than I was at the time clarify the relationship between these two standards?

They appear to be technically identical ( I don't have the EN one but contents are the same) so normally the ISO standard would replace the EN one, however both appear to be current and the standards institute pages don't cross reference them.

Is there some reason why they are running in parallel.?

I guess the EN is older (as the last issue is from 2012) where as the ISO was released last in 2017. Refer to https://www.iso.org/standard/57780.html & https://www.iso.org/standard/72430.html

You may ask the ISO/TC 135/SC 3 Ultrasonic - check this page https://www.iso.org/committee/52410.html for contacts.
Head of the TC135/SC3 is Thomas Heckel, from BAM Berlin see this page of DGzfP for contact details http://www.dgzfp.de/Arbeitskreise/Berlin/AK-Leiter

I am on that committee...But didn't attend the relevant meetings.
It seems there was the intention to replace the EN standard, but it doesn't seem to have happened.
Wondered if there was any other reason.

Joe,

ISO 16809 and EN 14127 should'nt run in parallel.
ISO 16809 is also an identical EN ISO 16809. Therefore it should replace EN 14127.

ISO 16809:2017-11,
Non-destructive testing - Ultrasonic thickness measurement.

EN ISO 16809:2018-11,
Non-destructive testing - Ultrasonic thickness measurement (ISO 16809:2017).

Against EN 14127:2011 the following changes have been made:
a) Terms have been improved to comply with ISO 5577;
b) Formulas (5) and (6) have been corrected;
c) the whole document has been editorially revised.
(EN 14127:2011, Non-destructive testing - Ultrasonic thickness measurement)

With best regards
