5.1 Appearance quality
Surface quality is tested by self-test and inductive powder test. If there is any dispute, remove the stone by the agreed method and use 15 times the magnification to check vertical. 5.2 Chemical analysis
The chemical composition of the wire is carried out according to GP/T4325. 5.3 Specifications
5.3.1 Diameter
Aluminum wire with a diameter greater than 4m The wire is measured with a grade 1 ruler. A measuring point is taken at a distance of 1m. The value is taken as the average value of the result. The wire with a diameter of 20mm should be accurately measured with a torsion balance. The average value is 2mm. The wire diameter should be within 100m44cm. The wire with a ruler should be measured with a diameter of 25K::nm/g

For wires with a diameter less than or equal to 400m, the reading from the burning machine is used as the length measurement value. For wires with a diameter greater than 400m, the measurement value is taken from the mass disk.
5. 4 Linearity
Linearity calibration shall be carried out using an eyeglass and a ruler according to the following methods. 5.4.1 Gradient
Take a wire of 500mm in length, let it droop naturally, and measure its total quotient H (see Figure 1). 5.4.2 Chord method
Take a wire of 20mm in length, place it on a smooth surface and measure the chord height corresponding to a chord length of 100m with a ruler (see Figure 2).
