The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. This practice is based on experience with ferrous and aluminum alloys.

For thin sections, it may be possible to use a single stand-off position with either E-scans or S-scans. If the source of sensitivity change is a result of change in the number of active elements compared to the baseline assessment it may require probe replacement.

For additional pertinent information, see Practices EEand E Data, in the form of A-scans from each focal law used, shall be collected at increments of not greater than 2 mm with at least three increments for the length of the smallest required detectable defect, that is, a defect length of 3 mm would require increments of not greater than 1 mm along the scan axis.

The values given in parentheses are for information only. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

Practice E recommends methods of assessing performance characteristics of phased array probes and s2700. If this is the case, e27000 another hole at 1? The lateral movement atm each raster step shall not exceed half the element dimension in the lateral direction.

ASTM E Standard Practice for Contact Ultrasonic Testing of Welds Using Phased Arrays

Greater and lesser thicknesses may be tested using this standard practice if the technique can be demonstrated to provide adequate detection on mockups of the same wall thickness and geometry. With their distinct features and capabilities, phased arrays require special set-ups and standardization, as addressed by this practice. In addition, the alternative method and its equipment shall meet all the performance astn of this standard. Commercial software permits the operator to easily make set ups without detailed knowledge of the phasing requirements.

Commercial software permits the operator to easily make set ups without detailed knowledge of the phasing requirements. Apply the correction to all focal laws used for the examination. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

Other metallic materials can be examined using this practice provided reference standards can be developed that demonstrate that the particular material and weld can be successfully penetrated by an ultrasonic beam.

Probe placement will be de? The practice or standard used and its applicable revision shall be identi? Descriptive sketches are usually recommended.

A number in parentheses indicates the year of last reapproval. If laterally focused beams are used, this can be considered for data collection increments as above. For thin wall sections, a single probe stand-off may be possible for linear scanning if the probe parameters are adequate for full volume coverage. Welds shall be inspected from both sides, where possible. Link to Active This ashm will always route to the aztm Active version of the standard. Basis of Application 6.

ASTM E – 14 – Standard Practice for Contact Ultrasonic Testing of Welds Using Phased Arrays

With their distinct features and capabilities, phased arrays require special set-ups and standardization, as addressed by this practice. While some scan patterns emulate manual technology, other scans for example, S-scans are unique to phased arrays.

In manual scanning, the dominant display will be an S-scan with associated A-scans.

Active view current version of standard. Personnel performing examinations to this standard should list the qualifying credentials in the examination report.
