The football inspection is carried out by sampling according to the sampling standards. First, the outer box labels, model numbers, specifications, and quantities are checked to ensure that the packaging and tags match the order. The appearance is inspected to check for any damage, scratches, bubbles, color differences, or glue peeling on the surface of the ball. The alignment of the splicing pieces is checked to ensure there is no misalignment, and the printed patterns are checked for clarity without ink fading.
The inflation test is the core. The ball is inflated to the standard pressure, and then left to stand for a period of time to check for any leakage. The roundness of the ball surface meets the standards, with no bulges or deformations. The ball mouth is checked to ensure it is securely installed, and the inflation is smooth without leakage.
Manual pressure is applied to the surface of the ball to feel if the elasticity meets the requirements, and the seams / adhesion areas are checked for firmness. The weight is measured to measure the circumference, and the size parameters are checked. The error is controlled within the allowable range.
At the same time, check if there is any pungent odor on the surface. Randomly perform a light drop test to observe if the surface detaches from the glue. All defective positions are photographed for evidence, and all test data are recorded. The batch is judged as qualified based on the comprehensive assessment to avoid quality risks during shipment.
