The condition, method and demand of the test

Color

Metal surface presents bright silver, no rust. no scratch, no corrosion and so on

Plainness

Put the test piece on bare board, parallel completely. No wrinkle. No burts.the surface’s roughness RA is 0.8um

The size of sheet iron and cutting groove

The side length of test piece tested by milscale is 0.75in×0.75in.

The average thickness of test piece CX-230 is 0.002in.

The artificial defect symbol “o”and symbol“+”tested by precision microscope are both on the center of the test piece.

The diameter of symbol “o”is 0.507in,symbor“+”is 0.25in.

The thickness of test piece CX-230 is 0.002in.

The groove depth is 0.0008in; the groove width is 0.007in.

Quality

The physics and chemistry test show the result that the metal is made from 1005 Steel Park electromagnetic pure iron plate.

The analytic result of raw materials accords with the rule of GB6985,
