What are the laboratory accreditations?

  • NGB's and GGB's authorise third party Test Institutes to perform testing to allow the NGB/GGB to issue certificates for fields tested by authorised Test Institutes. 

How long does it take to certify our product in the Laboratory?

  • Sports Labs have a guarantee of a 5 week turnaround on products tested.

What are the player surface interaction tests?

  • Tests such as shock absorption, friction, traction and deformation all relate to athlete/surface interaction. 

What are the ball surface interaction tests?

  • Ball bounce/roll, are the main tests here.

What tests are carried out to assess product safety?

  • The safety of a surface is determined through physical tests such as shock absorption or head injury criterion.

What tests are carried out to assess product durability?

  • Simulated wear testing is carried out in the Lisport XL.

What are the sample sizes required for lab testing?

  • 1 x 12ml x 1mw sample for ball roll.
  • 2 x 1m x 1m x 1m samples for other physical tests.
  • Necessary infill materials.

Where do I send products to be tested?

  • To Sports Labs UK, see contact page on this web site for details.


What is Goal Line Technology?

  • This technology allows for an independent system to verify if a goal has been scored in a game of football.

How do you test for GLT?

  • Using an accredited Test institute with a high speed camera

What are the tolerances of the testing?

  • Currently the technology used for calibrating the system is accurate to 15mm only.

What GLT installations have been tested?

  • The English FA - Premier League
  • World Club Competition, Morocco
  • Wembley
  • The KNVB League
  • Womens World Cup Canada


What are the contact details for Sports Labs in different locations?

  • See Global contact list on the Field Testing page.

What is the difference between 2G / 3G / 4G?

  • The various generations (G's) of turf i.e. second generation refers to sand infilled type turf systems. 3G refers to third generation type surfaces mainly infilled with sand.                                                                                                    

What footwear should be used on 3G fields?

  • There are certain types of footwear that should not be used on 3G and some that are suitable. Traditional 8 studded football boots are mainly satisfactory. However every manufacturer has their own recommendations and these should be strictly adhered to.


How do I prepare a field for testing?

  • Ensuring the field is ready for test is important to reduce the chances of needing a retest and also to understand the surface condition. There are several simple site inspections / checks that can help ensure your field is ready for the test. Testing the ball roll or rebound with the equipment, sold at low cost by sports labs, or even checking the infill depth, with a sport labs depth probe can help.

What samples do I need to provide for FIFA fields?

  • The Laboratory has a responsibility to ensure that the materials used on-site match those in the original laboratory tests on the artificial turf system. Infill; sand and rubber, a artificial turf sample, yarn samples from the field of play is therefore all taken from site. There can be some small variation allowed between the original declared values and the field but these variations must be controlled by the manufacturer/contractor.

What do I need for field certification?

What are KSI’s (Key Stage Inspections)?

  • Key stage inspections are a tool engineers and Test Institutes use during the construction phase of a sports pitch or track. They usually involve a visit by an experienced engineer to assess the quality, compliance and conformance of a section of the works often referred to as milestone phases in the construction process. Key stage inspections or KSI's often involve testing activities.

What are the most common problems on fields?

  • Construction related issues: often problems with the levels or stability of the base foundation are found at completion where a test is commissioned to assess the compliance of the pitch or track against a standard - too late in most situations
  • Installation related issues: poor infilling, trapped fibre and uneven fill can lead to poor test values from location to location. Many other issues are observed such as poor seaming, patching in the turf or track, contamination, the wrong materials are supplied.

Ball Roll has failed, how do we fix this for the retest?

  • If due to pile flattening or trapped fibre then the field may need extensive brushing, toping up with rubber and possibly timing to free up the trapped fibre too.

How long does the testing and field certification take?

  • With Sports Labs Testing Buggy a mere 5 hours! Under normal circumstances it would take a day to test a field.

Do I need a ball roll ramp and maintenance equipment on site for FIFA fields?

  • Yes every FIFA certified field requires this equipment to be present on site

How often are the tests to be carried out?

  • FIFA type testing for quality pro is annual, quality can be every three years, World Rugby is bi-annual and the FIH is every three years. EN is a once off test. Our recommendation is that an annual test should be carried out especially where football or rugby is played. 

How do I get my FIFA certificate?

  • FIFA are the only organisation with the authority to issue a FIFA certificate.

How do I organise a field test?

  • Call Sports Labs of course! See contact on this web site.
