FIFA to issue new manual next week

FIFA will issue the new Handbook of Requirements and the Handbook of test methods for the FIFA quality concept for football turf. 

This much talked about update has involved some radical changes to the preparation and evaluation of football turf for FIFA certification.

The new manuals will be available for download next week we will post a link. 

The new manuals will be available for download next week we will post a link. 

The new FIFA quality pro and FIFA quality perhaps making a clearer distinction between community and pro fields this is a welcomed change.  A new Lisport XL is making it debut and new tests for infill splash, heat on surfaces and yarns for UV and thickness to name just some of the changes in this a fairly significant overhaul of the 2012 version.

Sports Labs will be providing a detailed communique on the changes early next week or better still come see us on our stand at FSB next week.

New video capture of infill splash on 3G surfaces

Watch this short video to see how we capture the infill splash on a 3G surface. This new method of filming will enhance the test and results and create a new tool for characterising the infill splash on 3G surfaces [youtube http://www.youtube.com/watch?v=ocfkpUyMBUI?rel=0&w=1280&h=720]

Sports Labs research adding maintenance applications to the Lisport test

Sports Labs in conjunction with Strathclyde University focused on one of the draw backs of the Lisport test which is the simulation of maintenance of the surface under test. The Lisport involves assessing the wear of artificial turf by simulating extended periods of use. One of the major short comings of this test is that it does not take into account maintenance which is performed on artificial turf and the effects this has on the wear of the turf over time. Therefore the aim of this project was to implement maintenance procedures into the Lisport. These will include brushing, which levels the infill and tining, which helps to prevent compaction of the infill. The final solution will aim to be fully automated in order to limit the technician time required for the operation. Here we have the student group who carried out the Lisport research.

Infill Splash; Conclusion from study

Image Infill Splash Research Sports Labs in conjunction with Napier University in Edinburgh have been researching the issue of infill [rubber] splash in 3G Football Turf systems. The purpose of the research was to produce a test method to assess the infill splash of filled 3G systems. The test should be able to measure the splash and rank systems in terms of low to high degrees of splash and characterize the splash in terms of the issues this may cause to television viewing.

The test was set up to look at ball/surface interaction and not player surface interaction, the theory being that the ball surface test may to some extent simply identify systems prone to splash whether ball or person interface is the mode of impact. This assumption as yet has not been tested by Sports Labs and may form the subject of further future research.

As with all research projects, this tends to pose more questions some of these questions will be discussed in the coming weeks.

Principal Conclusions from Research

  • The amount of free pile (pile exposed above the infill) affects the amount of infill splash, high values of free pile reduces infill splash.
  • A firm substrates [stone, asphalt] does reduces infill splash, shock pads in a direct comparison increase infill splash values.
  • A thatch pile within an artificial turf does not reduce infill splash.
  • Pile density does influence infill splash; higher density artificial turf does influence infill splash positively.
  • Green coloured infill is less obtrusive then black SBR when filmed under test.
  • The grading and shape of the infill does not appear to influence the degree of infill splash.
  • 40mm pile height artificial turf appears to have high infill splash values.

Clearly it would be useful to test systems which purport to be low splash in the next phase of the study. Also it would be helpful to have other Labs to use the test to assess inter Laboratory reproducibility following on from this. We will make some improvements to the test when it is introduced to the Lab for general evaluation again these will be discussed in the coming weeks.

Infill splash; preliminary conclusions from research project

Preliminary conclusions from research project into infill splash 330 videos and 990 photographs were gathered during testing. From these, 108 graphs were produced. Upon analysing these graphs, the following conclusions were drawn:

A test has been developed to characterise the infill splash as a result of ball impacts on football turf systems at various angles and speeds. By use of well documented apparatus and high speed camera work the results of the tests can be measured and recorded. Repeated testing of products is suggestive of reproducible results. The height of splash and distribution of fill over an impact area are of lower significance than the T.V categorization would suggest 'in general'. A lower pile weight can be compensated for by high free pile, and vice-versa. • Generally, the higher the free pile, the lower the test values for splash. • Coloured EPDM (green) was less noticeable than the Black and or Brown SBR’s on the camera. • Testing the surface when wet gives lower, or better, results than dry testing.

Does the test measure typical ball impact on the surface? We need to examine TV footage of games to study ball impacts on a field with ball impacts in the Laboratory. Can we rank products with the test? From the data collected it would appear we can rank products as problematic or low splash we need to work on a system to rank products.

The research work will continue so that the test and results can be developed then peer reviewed.
