UNI EN ISO 16148
Gas cylinders - Refillable seamless steel gas cylinders and tubes - Acoustic emission examination (AT) and follow-up ultrasonic examination (UT) for periodi inspection and testing

The purpose of this International Standard is to provide a procedure for locating, detecting and evaluating the relevance of acoustic emission (AE) indications such as those from longitudinally oriented crack-like discontinuities.

...
Flowing gas (turbulence) can produce measurable emissions.
Considering this, acquisition of AE data shall commence at some pressure greater than the starting pressure (for example, one-half of the AT pressure).

Nel testo si parla di AE indication/s e di AE data. Si intende la stessa cosa (dati di emissione acustica)? O si tratta di cose diverse e va tradotto letteralmente con "indicazioni di emissione acustica"?
