ASTM E213,  Pratique normalisée pour le contrôle par ultrasons des tuyauteries et des tubes métalliques (Revision 2020)

Remplace ASTM E213 ( de juin 2014).

Standard practice for ultrasonic testing of metal pipe and tubing

This practice covers a procedure for detecting discontinuities in metal pipe and tubing during a volumetric examination using ultrasonic methods. Specific techniques of the ultrasonic method to which this practice applies include pulse-reflection techniques, both contact and non-contact (for example, as described in Guide E1774 and Practice E1816), and angle beam immersion techniques, both conventional and phased array. Artificial reflectors consisting of longitudinal, and, when specified by the using party or parties, transverse reference notches placed on the surfaces of a reference standard are employed as the primary means of standardizing the ultrasonic system. This practice is intended for use with tubular products having outside diameters approximately 1/2 in. (12.7 mm) and larger, provided that the examination parameters comply with and satisfy the requirements of Section 12. These procedures have been successful with smaller sizes. These may be specified upon contractual agreement between the using parties. These procedures are intended to ensure that proper beam angles and beam shapes are used to provide full volume coverage of pipes and tubes, including those with low ratios of outside diameter-to-wall thickness, and to avoid spurious signal responses when examining small-diameter, thin-wall tubes. The procedure in annex A1 is applicable to pipe and tubing used in nuclear and other special and safety applications. The one in annex A2 may be used to determine the helical scan pitch. This practice does not establish acceptance criteria ; they must be specified by the using party or parties.

ASTM E569/E569M,  Pratique normalisée pour le monitoring par émission acoustique de structures avec stimulation contrôlée (Revision 2020)

Remplace ASTM E569/E569M ( de janvier 2013).

Standard practice for acoustic emission monitoring of structures during controlled stimulation

This practice provides guidelines for acoustic emission (AE) monitoring of structures, such as pressure vessels, piping systems, or other structures that can be stressed by mechanical or thermal means. The basic functions of an AE monitoring system are to detect, locate, and classify emission sources. Other methods of nondestructive testing (NDT)...
