Testing standard for shoes and shoes

1. detection conditions

1.1 visual inspection should be carried out under suitable light conditions.

2. inspection gauge and tools

2.1 gauge: length 40mm

2.2 multi purpose locator

2.3 dividers

2.4 the accuracy of the shoe is 1mm.

2.5 the accuracy of the steel plate is 1mm.

2.6 steel tape measuring accuracy is 1mm

3. appearance quality inspection method

3.1 the appearance inspection of footwear is mainly based on visual perception, and in case of doubt, inspection tools and tools are the criteria.

3.2 inspection of the upper part.

3.2.1 for the length of the test, from the front of the shoe to the front end of the shoe to the front end of the front, the shoe length is measured with the cloth tape.

3.2.2 shoes for the back of the high test, later for the middle seam, the measurement of the mouth to help the upper end of the mouth, the height of the shoe, with a cloth tape to measure.

The inspection of 3.2.3 shoe door is measured by multi-purpose positioner.

Place the shoe on the bottom plate of the positioner. The center line of the front wall of the shoe is positioned in front of the positioning hall, and the rear positioning slide plate is moved to the appropriate position, so that the rear positioning pin is aligned to the center line or the back seam of the heel bottom wall, the height of the pparent scale plate and the angle of the master's horn are adjusted, the door of the double shoe is measured, and the horizontal door is based on the horizontal line of the door, and the other door is based on the mouth door.

The inspection of 3.2.4 rubber eye is centered on the center line between the front end and the bottom. The distance between the two sides of the rubber eye is measured by the divider, and the shoes need to be measured symmetrically with the pair of shoes.

3.2.5 shoe seam inspection, with the middle line of the sole as the standard, check the vertical line of the seam behind the upper, and measure with the steel plate ruler.

The test of 3.2.6 skew is measured by multi-purpose positioner.

The shoe positioning method is pressed according to 3.2.3, measuring the front of the mouth of the shoe to the end of the door.

3.2.7 needle test, the calculation of needle number: the straight line of two pinholes is measured continuously by a needle, and the length is straight.

3.2.8 the inspection of the Ming column with the length, with the shoe mouth to help the pillar and one end, the post to the outer side to the other end, take the total length, and measure the shoes with cloth tape ruler.

3.2.9 the inspection of the upper fabric defects, the length of the weaving defects, and the measurement with the steel plate ruler.

3.2.10 color difference according to GB 250-64 color fastness fading card.

3.3 inspection of sole parts

3.3.1 the thickness of the sole is measured. The thickness of the sole is usually measured by the thickness of the bottom wall. If necessary, the center of the metatarsophalangeal should be cut off and the thickness of the palm should be measured with the steel ruler.

3.3.2 the test of the number of rows in the inner part of the shoe is measured by the caliper gauge on the toe of the shoe.

3.3.3 the shoe heel height is measured on the platform (or flat object). The vertical height of the heel and the lower edge of the heel is measured with the steel plate ruler.

The inspection of the 3.3.4 shoe number is based on the bottom of the shoe. After the flat shoe with a high 2mm shoe is placed flat, the distance between the front and rear centerline and the inner edge of the bottom joint at the bottom of the bottom is measured by the shoe with a foot attached to the shoe bottom pad.

4. testing methods for physical and mechanical performance indexes

4.1 folding according to GB 3904-83 "footwear folding test method"

4.2 wear resistance according to GB 3905-83 "footwear wear test method"

4.3 peel strength according to GB 3903-83 "peel peel strength test method".

4.4 inspection of other physical and mechanical performance indicators shall be carried out according to the product standards.

5. inspection rules

6. if the test method in the product standard is inconsistent with this standard, the standard shall prevail.
