摘要：Temporary Edge Protection Systems (TEPS) are designed to withstand the impact of a worker that walks, stumbles, and falls against them. This is by nature a dynamic action; however, many standards evaluate TEPS when the surface or slope is slightly inclined (less than 10°), applying static requirements. The performance requirements demanded by these standards are assumed to be equivalent to the impact of a worker, however this point has not been tested. In this study, TEPS with tubular steel guardrails and wooden boards of different quality under two types of loads are evaluated using the static requirements detailed in standard EN 13374. TEPS are subjected to an impact energy of 180 J, simulating a worker of 90 kg walking at a speed of 2 m/s. The results demonstrate that the static requirements of EN 13374 are more demanding than the impact of 180 J in all the systems under study.
