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.

Evaluating Playground Surfacing System for Compliance with Performance Standards

The standardized procedure was compared with the shortened procedure, using regression analysis. When one of them reaches their respective limit, the injury has the potential to become a fatal one. More information about text formats.

Statistics for show that 6, people were killed by traffic accidents, while 7, people were killed by daily life accidents axtm fall accidents 1. MacDonald J, Greene M. Vital Statistics of Japan asrm However, the number of victims of accidents in daily life is greater than those caused by traffic accidents. We should be able to capitalize on all related research that has just been completed and is currently underway throughout the world.

Please review our privacy policy. The difference between the two procedures increased with drop height as same as in the case of G-max. Are unitary and loose-fill test samples r1292 the same as the surface system materials purchased and installed in each and every playground year in and year out? Generally, acceleration at the impact point is dependent on maximum speed.

Effect of declining of accuracy of shortening procedure As seen from the results of the regression analysis, the measurements in both of procedures have a range of error. These can be used to ensure that inspections are in compliance with the manufacturerssurfacing specifications.


Does this seem f192 While it is believed that conformance with the requirements of this specification will reduce the risk of serious injury and death from falls, adherence to this specification will not prevent all injuries and deaths. The laboratory test ashm mandatory for surfaces to conform to the requirements of this specification. The measurement procedure in Figs.

Factors that are known to affect surfacing material performance include but are not limited to aging, moisture, maintenance, exposure to temperature extremes for example, freezingexposure to ultraviolet light, contamination with other materials, compaction, loss of f12922, shrinkage, submersion in water, and so forth.

Evaluating Playground Surfacing System for Compliance with Performance Standards

The laboratory test is mandatory for surfaces to conform to the requirements of this specification. The asfm value to be added to the temporal score can be estimated by the transformation equation as follows.

These shall be compared with the results of the standardized procedure. Open in a separate window.

One example of a performance requirement established to reduce the likelihood of serious suspended component impact injuries is the new Dynamic Swing Impact Test Method and Impact Threshold. With this in mind, this study proposes a shortened measurement procedure and a transformation equation to estimate the risk as same as F As seen from the results of the regression analysis, the measurements in both f12992 procedures have a range of error.

There appears to be a performance conflict related to these two ASTM Subcommittees which occurs immediately following a serious fall-related playground injury. This means that different transformation equations are needed for G-max and HIC satm estimate the evaluation scores from the temporal scores by the shortened procedure. An informed consumer needs much more information to base their final decision, which goes beyond just initial cost and initial laboratory test performance.


There are many variables known to affect surfacing material performance including but not limited to the natural aging process, excessive or lack of moisture, maintenance requirements, many environmental factors, compaction, loss of thickness, shrinkage, and the list goes on. Therefore, measures toward minimizing the risk of fall accident injuries are required. The purpose of this specification is to reduce the frequency and severity of fall-related head injuries to children by establishing a uniform and reliable means of comparing and specifying the impact attenuation of playground surfaces.

This Standard establishes an impact attenuation performance criterion for playground surfacing materials. The problem of accidents involving playground equipment is serious not only in Japan, but also in many other countries.

The differences in outcomes between the regression equations ast the standardized procedure and those of the shortened procedure can be used as a correction value. Discussion Attenuation by loose fill material Variation of acceleration at the moment of impact depends on the drop height and sand depth. The shortened procedure can reduce the measuring time by reducing the number of tests compared with the standardized procedure for the installed surface performance test.
