- Description: Surface temperatures of synthetic turf have become a factor of growing interest and concern, particularly in warmer regions like Australia. However, it is unclear which components of the synthetic turf system contribute to surface temperature. The aim of this paper was to compare the surface temperature of 34 different synthetic turf products that were exposed to the same environmental conditions to ascertain which components of the synthetic turf system and which environmental factors contributed to increased surface temperature. A total of 6,120 observations were taken on the 34 products over the summer months, giving 30 observations for each of the variables on each product. An analysis of covariance (ANCOVA) indicated that the type of infill and shockpad had small-medium, but significant, effects on surface temperature (p<0.001 and p=0.003, respectively), and the interaction between shockpad and tuft gauge was also significant (p=0.047). Level of solar radiation, ambient temperature and relative humidity (p<0.001 in all instances) were the only environmental variables that significantly influenced surface temperature. These findings confirm that both the composition of the synthetic turf system and environmental factors contribute to synthetic turf surface temperature, thus providing important information for synthetic turf manufacturers developing new cool climate products, or for local government authorities selecting products and/or informing safe play for end-users.

- Description: Given the escalating drought conditions in Australia, synthetic surfaces have recently been explored as a viable surface option for community-level Australian football–cricket ovals. The vast majority of Australian football ovals are transformed into cricket pitches during the football off-season and hence the characteristics of both sports had to be duly considered in the development of standards that could be tested in a laboratory setting, for a synthetic turf surface. This paper describes the data collection and test methods undertaken in the development of the standards for synthetic surface use in Australian football and cricket. The paper also discusses the issues and challenges encountered during the development of standards for multi-sport synthetic surfaces to ensure player safety while maintaining the performance characteristics of both sports. Surface property and ball interaction tests were undertaken on natural playing surfaces, both in situ and in the laboratory to determine the properties of the current playing surface for each sport. This paper highlights the importance of careful consideration of the characteristics of both games and the use of equipment from both sports in the testing methods. The standards described in this paper have now been accepted by the Australian Football League and Cricket Australia and the product approval process and use of synthetic surfaces for Australian football and cricket is imminent.
