An equivalent standard is one which covers the qualification and certification of ultrasonic nondestructive examination candidates and which is acceptable to the purchaser. A is for steel plate and A is for alloy clad steel plate. Use a suitable couplant such as water, soluble oil, or glycerin. Your comments a758 invited either for revision of this standard or for additional standards and should be addressed to ASTM Sstm. The Navic is a modular, motorized, steerable scanner designed to carry multiple attachments used.
Available in both two-axis and three-axis instrument configurations and adaptable to cover a wide range of degree nozzle sizes, from 3″ upwards, on ferritic and austenitic materials.

Repeat the operation to establish the boundary. Three levels of acceptance standards are provided. A superscript epsilon e indicates an editorial change since the last revision or reapproval. The method will detect internal discontinuities parallel to the rolled sstm.
The amplitude linearity of the apparatus to be used shall be checked by positioning the transducer over the depth resolution notch in the IIW or similar block. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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 qstm the plate to be examined.

A clean, easily interpreted trace pattern should be produced during the examination.
Acceptance Level B shall apply unless otherwise agreed to by asmt and manufacturer.

Supplementary requirements are provided for alternative procedures. Combining values from the two systems may result in non-conformance with the standard. The surface of the reference block shall be no better to the unaided eye than the plate surface to be examined. The holes may be drilled in the plate to be examined if they can be located astk 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 w578 examined.
