scope:

1.1Â This guide describes procedures for electronically measuring the following performance-related characteristics of some sections of ultrasonic instruments:

1.1.1Â Power Supply Section:

 line regulation,
  battery discharge time, and
  battery charge time.

1.1.2Â Pulser Section:
pulse shape,
 pulse amplitude,
 pulse rise time, pulse length, and
 pulse frequency spectrum.

1.1.3Â Receiver Section:
  vertical linearity,
frequency response,
noise and sensitivity, and
dB controls.

1.1.4Â Time Base Section:
horizontal linearity, and
 clock (pulse repetition rate).

1.1.5Â Gate/Alarm Section:
delay and width,
resolution,
alarm level,
gain uniformity,
analog output, and
back echo gate.

1.2Â This guide complements Practice E317 and is not intended for evaluating the performance characteristics of ultrasonic testing instruments on the inspection/production line.

Note 1:Â No access to internal circuitry is required.

1.3 Unitsâ€"The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4Â This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5Â This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
