Referenced Documents 2. Apparatus 3. The equipment shall be of the pulse-echo straight beamtype. The test shall be performed by one of the followingmethods: direct contact, immersion, or liquid column coupling. Test Conditions 4. Procedure 5. Acceptance of defects in close proximitymay require inspection from the second major surface. Platesordered in the quenched and tempered condition shall be testedfollowing heat treatment.
Thickness, grain size, or microstructure of the material andnature of the equipment or method may require a higher orlower test frequency.
However, frequencies less than 1 MHzmay be used only on agreement with the purchaser. A clear,easily interpreted trace pattern should be produced during theexamination.
Current edition approved March 1, Published March Originallyapproved in DOI: Box, Arlingate Ln. Asuitable couplant such as water, soluble oil, or glycerin, shallbe used. An additional path shall be scanned within2 in. Mark the plate at a pointequivalent to the center of the transducer. Repeat the operationto establish the boundary. Acceptance Standards 6. Marking 7.

More A The equipment shall be of the pulse-echo straight beam type. Nondestructive examination of the material shall be conducted in an area free of operations that interfere with proper functioning of the equipment. The test shall be done by one of the following methods: direct contact, immersion, or liquid column coupling. Ultrasonic examination shall be made on either major surface of the plate. Grid scanning shall be continuous along perpendicular grid lines or shall be continuous along parallel paths, transverse to the major plate axis, or shall be continuous along parallel paths, parallel to the major plate axis, or smaller centers.
