Sports Field Safety Surfacing Inspections

ARTIFICIAL TURF AND IMPACT ATTENUATION

Certified in testing of synthetic turf to ASTM F1936-10 requirements (training certificate A72)

Certified to operate the Triax2015 Impact Tester (training certificate C664)

Types of fields tested:

  • Football
  • Soccer
  • Lacrosse
  • Field Hockey
  • Baseball and Softball
  • Unlined Fields

REPORTS
Most standards specify minimum content of
reports.  Reports must be free standing to cover statute of limitations for injuries and must
include:

  • Instrumentation confirmation
  • Drop height or velocity of drop
  • Include certificate of training and calibration
  • Depths of surfaces – system and infill
  • Temperature – ambient, system, infill

IMPLICATIONS FOR OWNER/OPERATOR

  • Ultimately the Owner/Operator is responsible for all aspects of the selection, specification, prior to use inspection and ongoing maintenance of a surface system to ensure compliance & prevent injury.
  • Failure to follow standards at any stage can preclude compliance and result in a preventable injury, negligence and liability.

FIELD TESTING (COMPLIANCE)

  • The highest degree of confidence for the owner/operator for compliance to standards and contract specifications
  • Especially important to surface systems with high degree of field assembly
  • Only way Owner/Operator can determine warranty compliance

IMPACT TESTING

FIELD TESTING PROBLEMS

  • Field testing is subject to the ambient conditions of the site
  • Field testing usually involves travel costs and delays can add to the costs
  • Weather conditions can be problematic for the instrumentation & test personnel

FIELD TESTING SOLUTIONS

  • Field testing for impact attenuation can provide baseline for depth testing
  • Field testing for depth of infill is less weather dependent than impact testing
  • Field testing for depth can be performed locally without need for travel
  • Weather conditions is less problematic for the instrumentation & test personnel

FIELD TESTING PROBLEMS
Temperature requirement in playgrounds and fields to test at ambient temperatures

  • Heat can affect electronic data acquisition devices for contrast, requiring special care
  • Heat is not a factor in the testing of depth of infill or the entire system

FIELD TEST LOCATIONS

  • Specified for testing of impact attenuation based on the sport-specific purposes
  • Depth testing is at the same sites as specified for impact attenuation
  • Depth testing is at any other site that is determined by owner or sport governing body

FIELD TEST LOCATIONS

For Turf fields the test locations are prescribed

  • Athletic fields are approximately 55,000 ft2
  • ASTM F1936 requires only 10 predetermined points for 283 ft2 of total field
  • Owner should require additional points & require random selection to determine compliance.
  • Expectation is the entire system complies when < 1% actually complies

FIELD TESTING

  • Test depth at 3 locations around each impact test location
  • NFL proposes 60 test locations prior to each game
  • Compare impact performance to depth of infill and ensure depth of surface is within range for impact test areas

TEST LOCATIONS FIELDS

  • Test locations have been determined as anticipated high traffic areas for the relevant sport
  • Test locations should include areas out of bounds where the athletes would be reasonably expected to play or fall.
  • Test locations should selected within 36 inches (91cm) radius of the stipulated location

TEST LOCATIONS FIELDS

  • Test each location for impact attenuation
  • Test each location for depth in 3 locations
  • Test temperature as follows;
    • For systems with pad measure at 0.5” (12.7mm) below fabric backing of pile
    • For infill systems measure 0.5” (12.7mm) below top of infill
    • Record the ambient air temperature
