BS EN 12668-1:2010 Non-destructive testing. Characterization and verification of ultrasonic examination equipment. Instruments BS EN 12668-1 is a European Standard which specifies methods and acceptance criteria for assessing the electrical performance of analogue and digital ultrasonic instruments for pulse operation using A-scan display, employed for manual ultrasonic non-destructive examination with single or dual-element probes operating within the centre frequency range 0,5 MHz to 15 MHz. Ultrasonic instruments for continuous waves are not included in BS EN 12668-1. BS EN 12668-1 may partly be applicable to ultrasonic instruments in automated systems but then other tests can be needed to ensure satisfactory performance Contents of BS EN 12668-1: Foreword 1 Scope 2 Normative references 3 Terms and definitions 4 Symbols 5 General requirements for compliance 6 Manufacturer's technical specification for ultrasonic instruments 7 Performance requirements for ultrasonic instruments 8 Group 1 tests 9 Group 2 tests Annex A (normative) Special conditions for ultrasonic instruments with logarithmic amplifiers Bibliography
