Background Firefly Sports Testing was commissioned to perform this on-site condition assessment per the protocol developed by Firefly Sports Testing. Standard test methods are performed together and held against a scoring system to provide a quantitative look at a range of important attributes. This broader perspective allows for more informed decision making.

Assessment Introduction At Firefly Sports Testing we understand the need for a qualitative approach to a quantitative assessment of sports surface condition. Therefore, we have created our surface scorecard condition assessment program. We have used our experience of testing thousands of surfaces to provide a qualitative look at surface condition using quantitative indicators.

This report has two main parts. The first part is the surface scorecard. This surface scorecard is a subjective scoring system that uses criteria based on commonly accepted ranges regardless of age to assess field condition.

Our surface scorecard is a cumulative point system that will yield a letter grade to reflect your surface's condition. The points awarded are based on 9 different surface properties tested / measured on-site. The results from each test are measured against four corresponding ranges of values to score each result. The ranges are classified as Poor (0 points), Fair (1 point), Good (2 points) and Excellent (3 points). This can be viewed in the results criteria.

Since each property has a different importance, it is assigned a "weight factor" based on the intended use and significance to the overall condition of the surface. For example, the impact safety tests have the highest weight factor. The weight factor can be viewed in the scorecard table.

The second part of this report contains background information and results graphs for each test performed. If you are not familiar with surface performance testing, then part 2 might be a good place to start to gain an understanding of the tests applied to the surface scorecard.

Part 2: Individual Test Background and Results Graphs

HIC Critical Fall Height (Hemispherical Drop Form) – ASTM F3146 The ASTM F3146 standard establishes a test method to be used when testing a synthetic turf field’s impact attenuation property for assessing its suitability for rugby and other sports. The method is similar to the method commonly used for assessing playground surfacing in the United States. The test device calculates the Head Injury Criteria (HIC). This is used to gauge the probability of head injury potential resulting from a surface impact. This device is a hemispherical 10 Ib “drop form” with a tri-axial accelerometer. The hemisphere is dropped from (4) different heights to determine the height at which the HIC would be 1000. This height is referred to as the critical fall height. It is recommended that the critical fall height values be greater than 1.3 m. The critical fall heights determined can be found in the graphs below and the Overall Results table above.

Turf Impact Attenuation (g-max) – ASTM F1936 The ASTM F1936 impact attenuation test method specifies the official device / method for assessing the hardness of synthetic turf athletic fields. It is used to gauge impact attenuation based on a predetermined head / body impact. The device uses a 20 Ib “drop form” with a tri-axial accelerometer dropped from a height of 24 in. The ASTM recommends that the g-max values be less than 200 g’s. The results can be found in the graphs below and the Overall Results table above.

Force Reduction – ASTM F3189 Advanced Artificial Athlete Protocol Force Reduction measures the shock absorption provided by the surface to a player under foot as they run. A lower value describes a surface that is harder underfoot and higher value describes a surface that is softer underfoot. As a field ages, these values will become harder (lower) over time. The results can be found in the graphs below and the Overall Results table above.

Rotational Resistance – EN 15301-1 Rotational Resistance measures the torsional resistance of a weighted apparatus with a standard cleat pattern that is rotated on a surface. The resistance is measured 5 times at each test location. A lower value reflects a surface with a low level of cleat release and a higher value describes a surface with more “grab” or cleat resistance. Please note that this test reflects the characteristics of the surface and does not take the athletes footwear into account. Footwear can dramatically impact the resistance experienced by an athlete.
