Aim:
Assess surface levels.
Method:
Measure the variation of the localized surface levels over the length of a 3 m straight edge.
Timing:
Anytime.
Effects of Incorrect Procedure:
- Poor surface playability.
- Risk to players/officials.
Equipment:
- Straight edge, wedge & spirit level.
- PQS Tables.
Practical Tips:
Substitute test equipment can be made of other materials particularly wood, i.e. goal uprights or crossbars, and metal. However, keep in mind that wood can warp and metals can be heavy and prone to rust (oxidation) so appropriate treatment and care should be exercised. The Straight Edge & Wedge can also be used, with a spirit level, to check gradients.
