Test Pieces

Verify penetrant sensitivity and performance

These test pieces for liquid penetrant inspection will help you maintain your PT testing process by verifying penetrant sensitivity and performance. Use to check for penetrant deterioration, to compare different penetrants or to verify sensitivity or visibility.

Magnaflux Product Description Part Number
Test Piece 2 according to EN ISO 3452-3

The EN ISO 3452-3 test piece is used for the routine assessment of fluorescent dye penetrants in environments where the penetrant could be susceptible to contamination and degradation.

The test piece consists of an austenitic base plate. One side of the piece comprises five different sized star-shaped cracks on a chromed background. Using this side of the test piece, it is possible to assess the relative sensitivity of a penetrant from one batch to another. The other side comprises four areas with differing levels of surface roughness; these areas can be used to make an assessment of the removeability of a penetrant during washing/cleaning.

Ni-Cr Test Panels Our Ni-Cr test panels provide feedback on the continuing sensitivity and performance of your penetrant processing system by comparing in-use penetrants against new, unused product to determine if the penetrant is performing properly. The test panels come in pairs and have set crack depths. 506251 - Pair of 10 µ panels
506252 - Pair of 20 µ panels
184400 - Set of 10, 20, 30 and 50 µ panels
Aluminium Test Block Use our aluminum test block as a liquid penetrant comparator. Complies with ASME Boiler & Pressure Vessel Code, Section V, Article 6. 070C001
