Summary of Practice 4. Checking Ultrasonic Response Characteristics 8.

An adequate air gap must be maintained at the hole bottom. It is the responsibility of the user of this standard to d428 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Last previous edition E — With the amplitude from the? The replica shall indicate that the hole bottom is? Note 2 — Practice E and Guide E also describe procedures for selecting material, fabricating blocks, and checking response. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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. Without changing any test parameters, the ultrasonic response from the remaining blocks with both shorter and longer distances are plotted on the response curve.

A number in parentheses indicates the year of last reapproval. Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material.

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

Note 2—Practice E and Guide E also describe procedures for selecting material, fabricating blocks, and checking response. Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material.

For record purposes, the replica may be projected on a comparator screen and photographed as shown in Fig. G—Hole bottom must be? 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. Active view current version of standard.

The physical characteristics of the hole may be established by evaluating plastic replicas. Where several sets and types of blocks are being used, a serial number identi?

Unlike this practice, Practice E has requirements for evaluation relative to a speci? On samples that are to have FBHs smaller than 3? 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.

The curve may vary when the test is performed at other frequencies with different diameter search units and different water-path distances or if a contact test method is used. This is particularly desirable in the cases of sets containing? If the ultrasonic-response characteristics are to be established by immersion techniques, the drilled? Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
