Historical Standard: ASTM E1158-98 Standard Guide for Material Selection and Fabrication of Reference Blocks for the Pulsed Longitudinal Wave Ultrasonic Examination of Metal and Metal Alloy Production Material
SUPERSEDED (see Active link, below)
ASTM E1158
1. Scope
1.1 This guide covers general procedures for the material selection and fabrication of reference blocks made of metal or metal alloys and intended to be used for the pulsed longitudinal wave ultrasonic examination of the same or similar production materials.
1.2 This guide covers the fabrication of reference blocks for use with either the immersion or the direct-contact method of ultrasonic examination.
1.3 Reference blocks fabricated in accordance with this guide can be used to determine proper ultrasonic examination system operation. Area-amplitude and distance-amplitude curves can also be determined with these reference blocks.
1.4 This guide does not specify calibration reflector sizes or product rejection limits. It does describe typical industry fabrication practices and commonly applied tolerances where they lend clarity to the guide. In all cases of conflict between this guide and customer specifications, the customer specification shall prevail.
1.5 This standard does not purport to address 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 to determine the applicability of regulatory limitations prior to use.
