What it covers
Three inspection stages: incoming material, in-process production, and pre-shipment. Every stage produces a written report with measured values against the approved specification.
Why it matters
Why it matters
Most defects in sporting goods are dimensional — a racket 4g over weight, a ball 1.5cm over circumference, a shaft softer than specified. These are measurable, so we measure them.
Details
| Racket weight | ±1g of target, individually weighed |
|---|---|

| Shaft stiffness | ±10% of specification, deflection tested |
| Ball circumference | ±1cm of official size |
| Ball weight | ±10g of specification |
| Bounce height | ±5cm from a 1m drop test |
| Appearance | Paint adhesion, logo lift and panel bonding checked |
| Sampling | ANSI/ASQ Z1.4 Level II, AQL 0.65 |
