Additional procedures and controls may be required when asm reference blocks from other than carbon or alloy steel material. Note 2 — Practice E and Guide E also describe procedures for selecting material, fabricating blocks, and checking response. For record purposes, the replica may be projected on a comparator screen and photographed as shown in Fig.

Individual reprints single or multiple copies of this aastm may be obtained by contacting ASTM at the above address or at phonefaxor service astm. The curve may vary when the examination is performed at other frequencies with different diameter search units and different water path distances or if a contact test method is used. This practice, however, must not be confused with, nor does it supersede Practice Especi?

Generally, nickel plating to a maximum thickness of 0. Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material.

Due to possible edge build-up during the plating process, this tolerance applies only to the area exclusive of that within 1? A number in parentheses indicates the year of last reapproval.

G—Hole bottom must be? The reference blocks described are suitable for use with either the direct-contact method or immersion pulse-echo ultrasonic methods.

The grain size, heat treat condition, physical and chemical composition, surface? The replica shall indicate that the hole bottom is? It must be recognized however that there are limitations on the size hole that may be replicated and evaluated.

ASTM E428 – 08(2013)

Block sets conforming to customary commercial practice are grouped as follows: Unlike this practice, Practice E has requirements for evaluation relative to a specified standard target. Note 1—Use of flat-surface reference blocks may not be suitable for cylindrical materials 3. On samples that are to have FBHs smaller than 3?

Unlike this practice, Practice E has requirements for evaluation relative to a speci? Therefore, consideration should be given to the e28 characteristics of the search unit and instrument generally available from the equipment manufacturer e28 evaluating the response curves from the reference blocks. This practice shall in asym way preclude the specification or addition of any supplemented requirements as deemed necessary for the specific application.

The reference blocks described are suitable for use with either the direct-contact method or immersion pulse-echo ultrasonic methods. This practice shall in no way preclude the specification or addition of any supplemented requirements as deemed necessary for the specific application. The machined counterbore may be omitted if this plugging technique is used. The acoustic noise level from the material is not to be confused with inherent electrical instrument noise often observed when the system sensitivity is adjusted to its maximum level range.

For example, the identi? Serial numbers are important when comparing sets of blocks to their respective response curves and to other sets of blocks. Additional supplemental requirements may be needed when using this practice to fabricate reference blocks from other types of astmm or with larger diameter holes.

Without changing any examination parameters, the ultrasonic response from the remaining blocks with both smaller and larger size re?

This practice, however, must not be confused with, nor does it supersede Practice Especifically governing the fabrication and evaluation of T6 aluminum alloy ultrasonic standard reference blocks.
