Abstract / scope
ISO 16811:2012 specifies the general rules for setting the timebase range and sensitivity (i.e. gain adjustment) of a manually operated ultrasonic flaw detector with A-scan display in order that reproducible measurements may be made of the location and echo height of a reflector.
ISO 16811:2012 is applicable to techniques employing a single contact probe with either a single or twin transducers, but excludes the immersion technique and techniques employing more than one probe.
