4.1 This test method specifies test procedures that can easily be used for field testing of equine surfaces. It is a test method that can be consistently applied to any equine surface and can quantitatively measure functional properties and track surface performance changes over time.

1.1 This test method covers the specification for the measurement of the functional properties of equine surfaces; cushioning, impact, firmness, responsiveness and uniformity. This test method specifies test procedures that are appropriate for field testing of equine surfaces. This test method defines the functional properties of equine surfaces. This test method does not specify safety criteria. The extent to which functional properties contribute to individual injury risk is not known.

1.2 Where appropriate values are stated in SI units.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
