Bringing the allowable GMax thresholds back to within reasonable limits is the current direction for most field designers and owners.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and awtm the applicability of regulatory limitations prior to use. Active view current version of standard. It should not be used, without some modifications, to test the finished products.
The asm shock pad system that set all industry standards for artificial turf fields. But there are three main reasons fields get hard over time when installed directly over stone: According to the Penn State Center for Turfgrass Science, impact attenuation of a playing surface is measured by an accelerometer mounted inside the missiles, that indicates surface hardness and is reported as Gmax.
Impact Machines: Sports Surface Testing Machine / standard ASTM F, F, F
Work Item s – proposed revisions of this standard. The GMax of a field is determined by dropping the missile 3 times in the same location asfm averaging the second two drops. Measuring impact-attenuation is a fundamental tool of athletic field safety testing. PowerBase Pro provides the ideal balance between shock absorption and field stiffness for elite athletes and is the only product engineered for NCAA, Pro and elite level players.
The values given in parentheses are mathematical 3f55 to SI units that are provided for information only and are not considered standard. The higher the g-max value, the poorer the shock-attenuation performance of the surface.
The higher the Critical Fall Height, the more protective the surface is for head injuries. It requires the missile to be dropped in a minimum of 10 locations around the field. A moderate head injury consists f535 a loss of consciousness, where a major head injury results in a skull fracture!

This specification covers a test method and the corresponding performance requirement for the maximum impact attenuation in all types of turf playing systems installed for North American football fields that is intended to establish a method for identifying and reporting areas within an existing playing system where shock-absorbing properties exceed recommended threshold values.
GMax Test – Brock International
Reduce risk of injuries by putting performance safety layers under the field. It is the responsibility of the user of this standard to establish appropriate safety and health zstm and determine the applicability of regulatory limitations prior to use. HIC is the internationally recognized test standard for head injuries.
All are considered concussions. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. This test method is applicable to natural asttm artificial playing surface systems and to components thereof. The Gmax test essentially measures how fast the drop missle stops.
ASTM F355 – 16E1
Smaller bodies need a different surface than the pros! ASTM does not give any warranty express or implied or xstm any representation that the contents of this abstract are accurate, complete or up to date. It is also useful in assessing the playability g355 a field. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
By partnering with leading testing facilities and universities around the world, Brock has been able to push the safety standards for the artificial turf industry forward.
All of these areas are regions where an athlete should expect compliant impact attenuation characteristics, but, it does not imply that an injury cannot be incurred if the surface system complies with this specification. Typical playing surfaces are wrestling mats, football fields, soccer fields, playgrounds, and so forth.

It also includes a protocol for determining test point locations on fields that are lined for multiple sports.

The turf playing system typically includes field areas within and outside the inbound lines extending to the sport astmm limit lines as defined by the appropriate regulating body or appropriate standard, or both. The safety of the playing surface only degrades over time. These alternate surface materials are not included in the scope of this specification. This test simulates the heel strike of an adult running athlete in stride.
For use under artificial turf. It comes in different thicknesses to optimize safety for the turf aastm select. This is our playground product.
