Key 1 Probe position 1 2 Probe position 2? Each location where indications to be recorded have been found, shall be marked and indicated in the test report. The backwall echo reductions to be recorded shall be marked and measured as indication areas.
All echo indications from discontinuities with measurable dimensions shall be recorded, when the signal amplitude exceeds both the levels given in Table 3 and the criteria given in Figures 3 and 4. Testing ej twin-crystal probes is only adequate for wall thicknesses up to 50 mm. For the identification of the type of indication, the test sensitivities can be changed according to: Defense manufacturing is all about project manufacturing and project accounting.
This European Standard applies to the ultrasonic examination of steel castings which have enn received a grain refining heat treatment and which have wall thicknesses up to and including mm.
This standard is also available to be included in Standards Subscriptions.
