Ball for Euro 2008

1. weight. The weight of European pass is between 44 1-444 grams, and FIFA's requirements for match balls are between 420-445 grams. 2. Circumferential parameters. The European pass is between 69.0 and 69.25cm, and the FIFA standard is between 68.5 and 69.5cm.. 3. Deformation parameters. The biggest difference between Europe and Europe does not exceed 1%, and the FIFA standard does not exceed 1.5%. 4. Water absorption performance parameters. It is said in Europe that the weight of the sphere will not increase by 4.5%, and the FIFA standard is that it will not increase by 10%. 5. Resistance to fecal parameters. The European Pass is 50 km/h with 3,500 hits, while the FIFA standard is 50 km/h with 2,000 hits. Springback performance parameters. The European Pass shall not exceed 2 cm, and the FIFA standard shall not exceed 10 cm. The European Pass is mainly composed of four colors: white, black, red and silver.

Like the "+Team Star" in the 2006 World Cup, "Eurolink" still adopts brand-new special-shaped blocks and seamless pressing technology, reducing the number of football spherical blocks to 14. More importantly, unlike the previous smooth skin making, this "Europa" adopts a brand-new PSC-Texture technology for the first time, and the surface cortex adopts a unique texture design, which greatly improves the transmission, rotation and accuracy of football in different weather conditions. For the goalkeeper, the non-smooth skin also increases the grip between the goalkeeper's gloves and the ball. Large-scale comparative experiments in Loughborough University in England and Adidas Laboratory in Schinfeld, Germany have proved this point.
