scope:

This document has two parts. Part 1 specifies four methods for the determination of the vertical water infiltration rate of different types of sports surfacing. Method A is suitable for measuring the vertical water infiltration rate of synthetic, textile and synthetic turf sports surfaces in the laboratory. Method B is suitable for on-site measurements of the Vertical Water Infiltration Rate of synthetic, textile, synthetic turf and bound mineral sports surfaces. Method C is suitable for on-site measurements of the vertical water infiltration rate of natural turf sports surfaces. Method D is suitable for measuring the for on-site measurements of the vertical water infiltration rate of unbound mineral sports surfaces. NOTE - For filled synthetic turf and unbound mineral surfaces, laboratory tests are considered to give a more precise indication of how a surface will perform. Part 2 specifies a method for determining the horizontal water flow rate of synthetic, textile and synthetic turf surfaces in the laboratory.
