Thermobonded Size 5 Football FIFA Pro F900, White

Design

For This Fifa Pro Quality Football, Our Designers Have Used Thermobonding Technology (Seamless) To Guarantee Perfect Sphericity And More Precise Shots. In Addition, This Technology Ensures Better Waterproofing While Training In The Rain. Finally, To Optimise The Sphericity Of This Ball, We Chose A Laminated Bladder (Fabric Strip Bonded To The Latex Bladder) To Guarantee Even More Durable Inflation. ,

Exclusive Construction

We Know That During Matches, The Details Make The Difference. For This F900 Ball, We Wanted To Pay Particular Attention To The Stability Of The Balls Trajectory To Ensure Players And Goalkeepers Had The Best Chance Of Following The Ball Through The Air. To Do This, We Tested Different Types Of Outer Panelling And Chose The One Which Showed The Best Results. This 12-Panel Design Combined With The Embossed Lines Is Exclusive To Kipsta. ,

Fifa Pro Quality Test

We Have Conducted Numerous Lab Tests On The Ball In Order To Provide The Excellent Accuracy That Football Players Require While Competing. Each Test Is Outlined Below. ,

Weight

Between 430 And 445G In Size 5,

Circumference

Between 68. 5 And 69. 5 Cm. ,

Sphericity

Average Measured Variation Maximum 1. 5%. We Measure The Footballs Sphericity At 16 Different Points And Examine The Recorded Discrepancies. If The Discrepancy Is Greater Than 1. 5% (Fifa Pro Standard), Our Engineers Are Tasked With Improving The Sphericity To Ensure A Consistent Bounce. ,

Maximum Pressure Loss

We Inflate The Ball To The Recommended Pressure (Meaning 0. 8 Bar). 72 Hours Later, The Ball Must Not Lose More Than 15% Of Its Pressure, Meaning Approx. 0. 1 Bar. The Pressure After 72 Hours Must, Therefore, Be At Approx. 0. 7 Bar. This Also Means That It Is Quite Normal For A Ball To Lose Pressure After A Few Days. ,

Water Absorption

We Simulate Rainy Playing Conditions In A Lab By Leaving The Ball To Sit In 2Cm Of Water On A Pivoting Support Whilst Subjecting It To 250 Compression Sat The End Of The Test, The Ball Can Not Have Absorbed More Than 10% Of Its Weight, 40 Grams For The F900. This Is One Of The Advantages Of The Thermobonded Process; Water Absorption Is Limited In Comparison To Other Processes (Machine-Stitched For Example),

Bounce

Between 135 And 155 Cm With A Maximum Difference Of 10 Cm Between The Balls Highest And Lowest Bounce. Each Ball Is Dropped 10 Times On A Steel Plate From A Height Of 2 Metres. The Bounce Obtained With The F900 Ball Complies With Fifa Pro Requirements. , 0

Shape And Pressure Retention

The Most Demanding Test That This Ball Is Subjected To Is The Machine Shot Test. Withstands Up To 2500 Shots Against An Inclined Concrete Surface At 50 Km/H At A Distance Of 2. 5 M. At The End Of The Test, We Check- The Balls General State Stitching Must Withstand This Test- The Circumference Must Not Have Increased By More Than 1. 5 Cm. - The Sphericity It Must Not Have Varied By Over 1. 5%- The Pressure Loss Of Pressure Must Not Exceed 0. 1 Bar. ,
