ASTM F1292 PDF

ASTM F MEASUREMENT PROCEDURE. FOR FALL ACCIDENT INJURY CRITERIA. Macky KATO1, Yoshie SHIMODAIRA2, Takeshi SATO3 and Hiromi. specification for playground surfacing performance (ASTM F). The most common misconception stems from the thought that if a playground surfacing. F, the voluntary standard for measuring impact attenuation of can meet the impact attenuation requirements of ASTM F, as long.

Support Center Support Center. Although it was said that F should be improved in the past study 15the specification has been conventionally applied as the standard evaluation method for loose fill materials for a long time and it was renewed in This has led to some initial studies of various surface systems by government granting agencies and an increase in requirements for procurement of surfacing systems to assure standard compliance and protect the owner, designer, manufacturer, and installer prior to the opening of the playground.

The effect increases with sand depth.

Accessed August 30, I for one do not subscribe to this notion and believe that a well thought out research study g1292 analyzes all the factors related to the cause and effect of falls injuries will show: G-max is the measure of the maximum acceleration shock produced by an impact. Protecting children from injuries caused by fall accidents from playground equipment is important.

The information necessary to maintain compliance with these Standards should include everything related to maintaining performance including, f12292 not limited to installation requirements; maintenance procedures and special materials f1229 tools required; inspection frequency; routine and foreseeable maintenance requirements; and repairs required to keep the system in compliance with ASTM F and the various impact-attenuating surfacing standards as referenced and implied below.

For example, the levels of injury and death in sports are also so serious that numerous studies have focused on the attenuation of impact 89 Who falls to the surface, how they fall, where they fall from, what part of the body first impacts the surface, and what they fall upon including a myriad of surface material physical properties and environmental factors. The number of victims of traffic accidents has been decreasing over the last decade. When a risky playground equipment is noticed by the shortened procedure, the observer would be able to obtain accuracy of the standardized procedure.

Once an accident involving playground equipment occurs, caretakers often remove the equipment in order to prevent future fall accidents.

Evaluating Playground Surfacing System for Compliance with Performance Standards

J Athl Train 44— Incidentally F defines a standard method of evaluation for children who are under the age of two In addition, Sand has also been tested as another attenuation material for outdoor playgrounds. National Center for Biotechnology InformationU. Generally, acceleration at the impact point asttm dependent on maximum speed. The surfaces at the impact point were the bare ground or loose fill surface.

Pediatrics— Web page addresses and e-mail addresses turn into links automatically. What if any d1292 injuries have we reduced over the past 30 years?

Arguably, advocates for injury prevention would like to see a decrease in public playground injuries requiring emergency room treatment. The astn procedure can estimate more exactly than the shortened procedure, however, this specification cannot prevent all injuries and deaths I do not believe any of these things will add substantial cost to the surface system.

The standard includes procedures allowing surfacing materials to be performance-rated before installation and for installed surfacing materials to be tested for conformance with the specification. It is probably a combination of all of these factors. G-max by the standardized procedure is larger than that by the shortened procedure because of the effect of the impacting tamper and repeats of trials.

The missile is used in two procedures, a standardized procedure in accordance with F and a shortened one. Work Item s – proposed revisions of this standard. They include administrative phases such as obtaining permission from the caretakers of the playground. On the other hand, coefficient difference 1f292 the HIC depends on both of the drop height and sand depth.

Evaluating Playground Surfacing System for Compliance with Performance Standards

They can be added to the value measured by the shortened procedure. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Use of appropriate impact-attenuating surfacing materials in the use zone of playground equipment can reduce the risk of fall-related injury. Some have concluded because of incomplete data or incomplete gathering of pertinent information related to this analysis that only by reducing the fall height can there be any significant xstm of injuries from falls. If the surface is found to be out of compliance, they are to take the playground out-of-service until the equipment or surface within the accessible route or use zones are brought into compliance.
