ASTM E1419 Document Information:
Title
Standard Practice for Examination of Seamless, Gas-Filled, Pressure Vessels Using Acoustic Emission
ASTM International
Publication Date:
Feb 1, 2009
Scope:
This practice provides guidelines for acoustic emission (AE)
examinations of seamless pressure vessels (tubes) of the type used
for distribution or storage of industrial gases.
This practice requires pressurization to a level greater than
normal use. Pressurization medium may be gas or liquid.
This practice does not apply to vessels in cryogenic
service.
The AE measurements are used to detect and locate emission
sources. Other nondestructive test (NDT) methods must be used to
evaluate the significance of AE sources. Procedures for other NDT
techniques are beyond the scope of this practice. See Note 1.
NOTE 1—Shear wave, angle beam ultrasonic examination is commonly
used to establish circumferential position and dimensions of flaws
that produce AE. Time of Flight Diffraction (TOFD), ultrasonic
examination is also commonly used for flaw sizing.
The values stated in inch-pound units are to be regarded as the
standard. The values given in parentheses are for information
only.
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. Specific precautionary statements
are given in Section 7.
