适用范围：1 This International Standard establishes the procedures for measuring performance characteristics of components of pulse-echo ultrasonic non-destructive testing instruments including both analog and digital type instruments with screen displays. The aim is to establish uniformity of evaluation techniques, to form a basis for data correlation and for interpretation of results obtained from different laboratories and at different times. Note that this International Standard establishes no acceptance criteria; such criteria should be specified by user parties. The usual components of ultrasonic non-destructive testing instruments and the performance characteristics for which procedures for measuring these characteristics are included and listed in 1.2 to 1.6. 2 Power supply section: — line regulation — battery discharge time — battery charge time 3 Pulser section: — pulse shape — pulse amplitude — pulse rise time — pulse length — pulse frequency spectrum 4 Receiver section: — vertical linearity — frequency response — noise and sensitivity — dB controls 5 Time base section: — horizontal linearity — clock (pulse repetition rate) 6 Gate section/alarm section: — delay and width — resolution — alarm level — gain uniformity — analog output — back-echo gate linearity
