ASTM E587-00(2005)

Standard Practice for Ultrasonic Angle-Beam Examination by the Contact Method

SCOPE
1.1 This practice covers ultrasonic examination of materials by the pulse-echo technique, using continuous coupling of angular incident ultrasonic vibrations.
1.2 The values stated in inch-pound units are regarded as standard. The SI equivalents are in brackets and may be approximate.
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 and health practices and determine the applicability of regulatory limitations prior to use.
