Standard Test Piece - STANDARD TEST PIECE (STP) is designed to enable an operator to establish whether the X‐ray machine is in compliance with current regulations and there has not been obvious changes that might affect its performance to detect and display different densities of materials. - SINGLE WIRE RESOLUTION (TEST No.1) - A set of un-insulated tinned copper wires of size 24, 30, 32, 36, AWG or corresponding AWG wires are placed on Perspex sheet. The wires are laid out in 'S" shaped curves. The minimum requirement is to display 36 AWG wire not covered by step wedge for most of the machines. Metallic marker is provided using high-density material, so that AWG numbers in the Display are clearly visible. - USEFUL PENETRATION (TEST No.2) - Defines what level of details can be seen behind a thickness of known material. The requirement of this test is that the 24 AWG wire is seen under step wedge of 5/16 thickness of Aluminium. - MULTI ENERGY X-RAY (TEST No. 3) - With multi-energy X-Ray, it should be possible to distinguish between materials of different average atomic number. The use of sugar and salt samples encapsulated on the test piece of STP will check the material discrimination facility. A different color of sugar and salt on display indicate that the sugar/salt samples are shown in different color. - SIMPLE PENETRATION (TEST No. 4) - This test defines what thickness of steel the machine should be able to penetrate. The steel step wedge on the STP has steps of 2 mm from 14 mm to 30 mm with a lead strip, 1.5mm in thickness to check that the machine is above or below the requirement. The requirement will be different for different KV machines. - SPATIAL RESOLUTION (TEST No. 5) - This test defines the ability of the system to distinguish and display objects which are close together. The STP has copper plate with four sets of gratings (0.05MM, 1.0mm, 1.5mm and 2.0 mm). Each set consists of a horizontal group and a vertical group. The requirement is that a vertical and horizontal grating can be seen. - THIN METAL IMAGING (TEST No. 6) - This is to test the machine's ability to image thin metal. This involves thin strips of steel of varying thickness starting from 0.05 mm thickness placed in row and the requirement is to image steel strip. - THIN ORGANIC IMAGING (TEST No. 7) - This is to test the machine's capability for thin organic imaging. The test object incorporates plastic. - The STP must be placed with its longest dimension parallel to the direction of belt. - The STP should be placed in the best position for optimum performance.The optimum position of the STP on the belt depends on the x-ray source and detector arrangements, with the aim being to obtain the best result possible.
