Test method

1 whether the overall appearance of hand feel is correct, symmetrical, uniform, stable (parallel to the ground surface), clean, marking the full clarity of the Liu and whether there is no decolorization, pulp, cracking and other defects.

2 loose noodles, put the index finger and middle finger of one hand into the shoe, close to the inside, and the finger distance is 15-20mm. Use the thumb of the other hand to lightly press the side of the thumb in the two finger distance to see the change of the face. If wrinkles appear, the wrinkles will disappear after loosening.

3 sides surface crack and fracture surface

One hand shoe, the index finger and middle finger of the other hand are pushed into the shoe, and the top is tight to help the inside. The changes of the side surface are observed visually, for example, cracks appear on the coating layer, and the cracks are judged to be cracked surfaces.

The 4 bottom is fastness, one hand shoe, the other hand thumb pressing along the side of the mouth to see whether the glue is opened or disconnected.

5 heel assembly fastness, one handheld shoe, the other one holding and following, shaking in all directions, whether the feel and visual heel are loose.

6 the main heel and inner Baotou press with thumb and forefinger on 1/2 sides of the length and width of the sides of the main heel. Press the thumb in the middle of Baotou to see if it is deformed and restored to its original state.

Use hand to touch and help the inner Baotou and the master to determine whether they are in peace or not.

7 the length of the front shoe is measured with the shoe with a ruler and the front arm is measured. The length of the front end of the front end of the shoe to the center point or the specific location of the front door is measured.

8 after the height of the shoe, use the ruler with the ruler to close the middle seam, then measure the height of the middle point of the mouth to the upper end of the back.

9 the rear seam is skewed, putting the shoes on the glass plate, aligning the middle point of the back side with the steel square ruler, and measuring the maximum offset with the back seam of the upper part with the steel ruler.

10 whether the stitching distance is uniform and whether the line is neat or not.

11 the length of the outsole must be measured with the belt ruler for measuring the length between the front end of the outsole and the rear end point of the outsole (or heel).

12 the width of the outsole is measured with the foot strap attached to the sole of the shoe, and the length between the ends of the first to the fifth toe is measured (see Fig. 5).

13 other projects at the outsole shall be examined in accordance with the provisions of ZBY 78006.

14 heel height is placed on the glass flat, and the steel vertical ruler is used to measure the vertical height of the shoe buckle and the upper edge of the rear part to the lower end edge (see Figure 6).

15 front toe shoes are flat on the glass plate, and steel vertical ruler is used to measure the vertical height between the front end of the plane and the bottom of the bottom (see Figure 7).

16 heel dimensions are measured with vernier calipers.
