EN 1177 applies to impact-attenuating playground surfacing. It specifies test methods for surfaces intended to reduce the risk of head injury. ## What Is EN 1177? EN 1177 is a standard for impact attenuating surfacing. It is used for surfaces installed beneath playground equipment based on free fall height. This standard is distinct from SS 457 and EN 1176, which relate to playground equipment. ## Critical Fall Height (CFH) The concept in EN 1177 is the Critical Fall Height (CFH). This is the height from which a fall onto a surface is tested to result in a Head Injury Criterion (HIC) value below the specified limit. ## The Head Injury Criterion (HIC) Surfacing is tested by dropping an instrumented headform onto the surface to measure the Head Injury Criterion (HIC). Under EN 1177, HIC values are measured at the tested drop height. ## Surfacing and Equipment Costs ### Wet-Pour EPDM Rubber Pricing for EPDM surfacing starts from SGD90/sqm. If a concrete base is required, pricing starts from SGD100/sqm. ### Playground Equipment Playground equipment is governed by standards such as SS 457 and EN 1176. Equipment prices start from SGD350/sqm. Disposal services start from SGD3.50/sqft. ## Verification of Compliance 1. Test Certificates: Laboratory CFH test reports confirm the performance of surfacing systems at specific thicknesses. 2. Certification: Professional certification and impact testing services for playground surfacing start from SGD600. ## Key Takeaways - EN 1177 relates to the impact performance of playground surfacing. - The surfacing's CFH is tested against the equipment's free fall height. - HIC is measured at the tested drop height. - Impact testing and certification services start from SGD600.
