This document specifies methods and acceptance criteria within the frequency range of 0,5 MHz to 15 MHz, for assessing the electrical performance of digital ultrasonic instruments for pulse operation using A-scan display, for manual ultrasonic non-destructive testing with single- or dual-transducer probes. This document is also applicable for multi-channel instruments. This document can partly be applicable to ultrasonic instruments in automated systems, but other tests can be needed to ensure satisfactory performance.<\/p>\n

This document excludes ultrasonic instruments for continuous waves.<\/p>\n

This document also excludes ultrasonic phased array instruments, see e.g. ISO 18563-1<\/span><\/span>. If a phased array instrument has dedicated connectors for single- or dual-transducer probes this document is applicable for these channels.<\/p>\n
