diffference between ASTMA and ASTM A – Boiler and Pressure Vessel engineering – Eng-Tips
All discontinuities causing complete loss of reflection shall be recorded. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Use a suitable couplant such as water, soluble oil, aztm glycerin.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The holes may be drilled in the plate to be examined if they can be located without interfering with the use of the plate, in a prolongation of the plate to be examined, or in a reference block of the same nominal composition, and thermal treatment as the plate to be examined.
An equivalent standard is one which covers the qualification and certification of ultrasonic nondestructive examination candidates and which is acceptable to the purchaser.
Use the transducers at sstm rated frequency. Historical Version s – view previous versions of standard. Red Flag This Post Please let us know here why this post is inappropriate.

Current edition approved Sept. When this condition is observed it shall be investigated additionally by use of multiple back re?
The transducer skew axis can also be adjusted, encoded and locked.
Maintain this instrument setting during evaluation of the discontinuity condition. The manufacturer shall afford the inspector all reasonable facilities to satisfy him that the material is being furnished in accordance with this speci? At each increment the ratio of the two signals is determined. A is not only applicable to alloy clad plate but can also be applied to “normal” plate.

The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
The material shall be held for metallurgical review by the purchaser and manufacturer. As a result of the test by this method, the surface of plates may be expected to have a residue of oil or rust or ast. A curve is then plotted showing the deviations from the above established 2: Where parallel path scanning is performed and recordable conditions as in 6.

ASTM A – acceptance standard clarification
The amplitude linearity of the apparatus to be used zstm be checked by positioning the transducer over the depth resolution notch in the IIW or similar block. Acoustical similarity is presumed when, without a change in instrument setting, comparison of the back re? This procedure covers the standard and acceptance standards for straight-beam, pulse-echo, ultrasonic examination of rolled carbon and alloy steel plates. Just to start you off in your standards selection review exercise: Make and model of instrument, test frequency, surface condition, transducer q578 and frequencyand couplant.
