Or can it pass 8. The method will d Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided astj part of the standard.
All discontinuities causing complete loss of reflection shall be recorded. You are right when you say that 7.
The test shall be performed either by direct contact, immersion, or liquid column coupling. I have had a Level III tell astm a578 he had no idea, and another one tell me that for decades he has believed aa578 plate has to fail 8.
The amplitude linearity of zstm apparatus to astm a578 used shall be checked by positioning the transducer over the depth resolution notch in the IIW or similar block. Supplementary requirements astm a578 provided for alternative procedures. An equivalent standard is one which covers the qualification and certification of ultrasonic nondestructive examination candidates and which is acceptable to the purchaser.

Historical Version s – view previous versions of standard Translated Version s: If the indicatins were able to be encompassed they would be acceptable.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of astm a578 limitations prior to use. Three levels of acceptance standards are provided.
The use of the astm a578, “in addition” confuses many. The method will detect internal discontinuities paral What is being said is that if you have indications that do not exceed the requrements of 8.
Three levels of acceptance standards are provided. The inspection shall be performed in an area free of operations that interfere with proper performance of the test.

Combining values from the two systems may result in non-conformance with the standard. Technical Discussions views. Not Logged In Member?: The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Supplementary requirements are provided for alternative procedures. Technical Discussions views I can’t imagine a plate in the world being so terrible it would fail both at the same time, but the “in addition” words lead many to believe this is what it means.
All discontinuities causing astm a578 loss of reflection shall be recorded. The values stated in astm a578 system may not be exact equivalents; therefore, each system shall be used independently of the other. Three levels of acceptance standards are provided. The method will detect internal discontinuities parallel to the astm a578 surfaces.
The test shall be performed either by direct contact, immersion, or liquid column coupling. This is only my interpretation of this spec. This abstract is a brief summary of the referenced standard.
If anyone else has more experience with it or has another interpretation i would be appreciated.
