This is the softness or hardness under foot during play. HIC is the internationally recognized test standard for head injuries. GMax is one benchmark at which to rate each field. It comes in different thicknesses to optimize safety for the turf you select.
For use under artificial turf. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. This is our playground product.
Historical Version s – view previous versions of standard.
Put into perspective, the impacts forces allowed on an artificial turf surface are somewhat ludicrous. Bringing the allowable GMax thresholds back to within reasonable limits is the current direction for most field designers and owners. Beyond The G-Max Test: Work Item s – proposed revisions of this standard.
It should not be used, without some modifications, to test the finished products. The test method, aptly called the free-fall drop test, shall be performed at eight different test point locations for four specific types of surface systems, namely: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Measuring impact-attenuation is a fundamental tool of athletic field safety testing. Note 1—This test method may also be used to measure the shock-attenuation properties of materials used as protective padding, such as the padding on trampoline frames, football goal posts, gymnasium wall, shoulder pads, body padding, and so forth.
This test method is applicable to natural and artificial ff355 surface systems and to components thereof. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 specific limit lines as defined by the appropriate regulating body or appropriate standard, or both.
It is also useful in assessing the playability of a field.
ASTM F355 – 16E1
There are t355 measurements used to characterize safety and performance of a surface. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. But even considering these factors, a Brock field will consistently meet the ranges of natural grass.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. These alternate surface materials are not included in the scope of this specification. The higher the Critical Fall Height, the more protective the surface asmt for head injuries.

The original shock pad system that set all industry standards for d355 turf fields. The higher the g-max value, the poorer the shock-attenuation performance f55 the surface. The values given in parentheses are for information only. The Gmax test essentially measures how fast the drop missle stops.
The Xstm of a field is determined by dropping the missile 3 times in the same location and averaging the second two drops. 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.
Which is why quality natural turf is the benchmark for quality artificial turf.
Test providers can adapt the procedures and guidelines contained herein to tests performed on any turf playing system. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Reduce risk of injuries by putting performance safety layers under the field. It requires the missile to be dropped in a minimum of 10 locations around the field.
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. Link to Active This link will always route to the current Active version of the standard. Brock is not comfortable simply meeting industry expectations for Gmax ratings.
It drops a 10 lb hemispherical impactor from increasing heights to determine Critical Fall Height. Our standard for a field with Brock is pristine natural grass, because that is the surface that every athlete would rather play on.
Impact Machines: Sports Surface Testing Machine / standard ASTM F, F, F
And for good reason. 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. Typical playing surfaces are wrestling mats, football fields, soccer fields, playgrounds, and so forth.
The safety of the playing surface only degrades over time. Active view current version of standard. This test simulates the heel strike of an adult running athlete in stride. Asfm of f3555, climate, and maintenance or lack thereof.
