What happens when the rubber in the surface gets old and begins to be less resilient in a few years?
The results also showed readings at 9 feet- 204 G / 1056 HIC, the point at which it failed, and results at 7 feet- 170 G / 845 HIC (one foot below the determined CFH) required by the F1292 specification. In this case, the results show that the CFH was 8 feet, giving results of 190 G / 996 HIC while testing at 25F. The vendor will show a certificate along with the test results, proving the laboratory tested the vendor’s 3.5-inch PIP system. The sample will also get tested at three temperatures - 25 degrees Fahrenheit, 70 degrees Fahrenheit (ambient) and 120 degrees Fahrenheit.įor example, if you desire a poured-in-place rubber surface for your 8-foot playground equipment, you should ask for a copy of the certification from your vendor.
So if you ask for an ASTM F1292 test result, you will find three readings on the report - the height at which the surface failed, the CFH (the maximum height before the surface failed the test) and a foot under the CFH. The surface is tested to the point at which it fails. The max G that a surface can have is 200, while the max HIC allowed is 1,000. Those measurement readings are in a unit of measure known as a G and something called Head Injury Criteria (HIC). The Triax uses a head form that, when dropped on the surface, reports measurements of how well the safety surface absorbs the impact. What Is Critical Fall Height (CFH)?ĬFH is calculated by impact testing a safety surface with a device known as a Triax impact tester. Recently, ASTM International brought about some changes to this familiar playground surfacing standard, and everyone in the industry should know about these new requirements. It tests for the critical fall height (CFH) of a playground surface. Over 12,000 ASTM standards are currently in use around the world, written by over 143 technical standards-writing committees.An Explanation of the New ASTM F3351 Test Method for Specified Height and Why It’s ImportantĪSTM F1292 has been a safety standard since the early 90s. When a new industry seeks to develop standardization, companies in that industry often come together under ASTM in order to achieve the desired result. The standards created by ASTM are designed to enhance safety and improve the quality of consumer and industrial products. Previously known as the American Society for Testing and Materials, ASTM International develops a range of consensus standards that are adopted and used globally across industries. These tests are performed for a variety of industries including pharmaceuticals, automotive, cosmetics, food & beverage, medical devices and more. These testing methods provide an international standard by which various industries maintain regulatory commonality for quality control, contamination identification, formulation, trace analysis, investigative analysis, and more.
