FIFA.com - Football - Test Criteria

It's always refreshing to switch contexts for a subject you're immersed into.  I ran across FIFA's criteria for testing their balls, which is just good to take a look at.  Here's an excerpt from the write-up:

FIFA Quality Concept

The FIFA Quality Concept for Footballs is a test programme for Outdoor, Futsal and Beach Soccer footballs. Manufacturers have the possibility to enter into a licensing agreement for the use of the prestigious 'FIFA APPROVED' and 'FIFA INSPECTED' Quality Marks on footballs which have passed a rigorous testing procedure. As an alternative there is the possibility to use the wording 'IMS International Matchball Standard'. Footballs bearing this designation have passed the same quality requirements as 'FIFA INSPECTED' footballs. The use of this designation is however not subject to a licence fee and any association with FIFA is prohibited.

There are two levels of criteria for the three designations. Footballs applying for the category 'FIFA INSPECTED' or the technically equivalent 'IMS - International Matchball Standard' must pass the following six rigorous laboratory tests:

1. Weight
2. Circumference
3. Sphericity
4. Loss of Air Pressure
5. Water Absorption(replaced with,Balance' test for testing of Futsal balls )
6. Rebound Footballs applying for the higher 'FIFA APPROVED' mark must pass the six tests at an even more demanding level and must undergo an additional test:
7. Shape and Size Retention (Shooting Test)
