Standard Test Method for Ultrasonic Inspection of Aluminum-Alloy Plate for Pressure Vessels
|Publication Date:||1 November 2003|
|ICS Code (Aluminium products):||77.150.10|
This test method covers pulse-echo ultrasonic inspection of aluminum-alloy plate of thickness equal to or greater than 0.500 in. (12.7 mm) for use in the fabrication of pressure vessels. The ultrasonic test is employed to detect gross internal discontinuities oriented in a direction parallel to the rolled surface such as cracks, ruptures, and laminations, and to provide assurance that only plate that is free from rejectable discontinuities is accepted for delivery.
The inspection method and acceptance criteria included in this standard shall be limited to plate of the following aluminum alloys: 1060, 1100, 3003, Alclad 3003, 3004, Alclad 3004, 5050, 5052, 5083, 5086, 5154, 5254, 5454, 5456, 5652, 6061, and Alclad 6061.
This test method applies only to ultrasonic tests using pulsed
longitudinal waves which are
transmitted and received by a search unit containing either a single
crystal or a combination of
electrically interconnected multiple crystals. Ultrasonic tests
employing either the
This test method shall be used when ultrasonic inspection as prescribed herein is required by the contract, purchase order, or referenced plate specification.
The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
