ASTM SE 1025 Plate Penetrameters, X ray flaw detector
accessories, American Inspection Standards
ASTM SE 1025 Plate Penetrameters are normally used to conform with the American Inspection
Standards. They are rectangular plates, 2% inthickness of the specimen and of material
radiographically similar to the specimen. Each plate has three holes drilled equal in diameter to
1X, 2X,and 4X the plate penetrameter thickness. The minimum thickness of Plate type
penetrameter is 0.010’’. For Penetrameters greater than 0.180’’, these are supplied in disc form,
the outside diameter is 4X, with 2 holes 1X & 2X the thickness of the Penetrameter.
The chart below gives Plate Penetrameter Identification and thickness and a guide as to which
penetrameter to use for each material thickness.
