ISO 16811:2012规定了设置带a扫描显示器的手动超声波探伤仪的时基范围和灵敏度（即增益调整）的一般规则，以便对反射器的位置和回波高度进行可再现的测量。 ISO 16811:2012适用于采用单接触探头和单探头或双探头的技术，但不包括浸入式技术和采用多探头的技术。

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.
