Magnaflux Product Description Part Number
Aluminium Test Block

Use this test block to check the strength of in-use penetrants, by processing one half of the block with used penetrant, and the other half with fresh penetrant.

76 x 51 x 9.5 mm with a 3.2 mm wide groove that divides the face of the block in half.

Complies with ASTM E165 and ASME Boiler and Pressure Vessel code.
