Part 3 Pinhole detection method for aluminum foil This method is used to test the quality and price of aluminum foil. 2 Principle of method
Y5/T455.2—2003
Under the specified resource and light source, the transmittance of the intelligent needle emulsion is used to observe the twist number and measure the size of the hole, 3 pinhole box and glass penetration room
pinhole age measurement width, the pinhole box is of poor quality or high-end box, the wheel body is equipped with a piece of thick steel bar on the surface, the non-slope increase surface is less than 0.1, black paper is used around the inspection surface to block the light, the box is equipped with a mouth lamp, the light emitted by the moonlight lamp is evenly distributed in the box: the light inside the box is 2G0110, the transmittance is 100C1x, the light is evenly distributed on the measuring surface, and the ambient illumination is also […1x. 1. Each firm:
2·grid;
3 one room

The sample is taken from the test, and the sample surface is flat, and there shall be no mountain or folding. The test size should be as equal to or larger as possible. The test surface size can be measured by the test equipment approved by the supplier and the demander. 1
YS/T 455.220C3
Otherwise, the test selection cannot be covered to prevent the inspection from affecting the inspection effect. 5 Inspection
51 Double aluminum model surface is observed to see the pinholes. 5.2 The hole size can be measured by 10 times to 20 times the average size.
