摘要

这项研究评估了在新西兰一个受欢迎的商业滑雪场使用一到四个季节的租赁滑雪捆绑靴(S-B-B)系统的释放扭矩值。根据ASTM F1063-03、ASTM F1064-03、ASTM F939-06、ISO 13993: 2001和ISO 11088-2006 (E)的国际设备安全要求,确定S-B-B系统偏离参考释放力矩等级的比例。从整个滑雪板租赁车队中随机抽取9%(124台滑雪板/62对)的S-B-B系统样本,使用Wintersteiger校准机进行测试。在租赁船队中,I类偏差的比例很高:50%(2个季节),95%(3个季节)和64%(4个季节)。1类偏差不需要纠正措施;但是,需要增加采样。基于高百分比的I类偏差,应该检查整个船队。使用两个季节后,48%的S-B-B患者出现II级偏差,需要立即采取纠正措施。只有8%的租赁船队有III级偏差,需要从租赁船队中移除。使用了两个或两个以上季节的S-B-B鞋跟超出耐受性的可能性是只使用了一个季节的鞋跟的9倍;然而,与较新的S-B-B系统相比,旧系统的脚趾片超出容忍度的比例仅略有增加。这些差异可能是由于年龄或S-B-B系统的不同模型。滑雪租赁设备使用三到四个季节后就退役的政策似乎不足以确保安全设备的供应。语言:在

Evaluation of Ski-Binding-Boot System Safety Using Torque Testing
This study evaluated release torque values for rental ski-binding-boot (S-B-B) systems that had one to four seasons use in a popular New Zealand commercial ski area. The proportions of S-B-B systems in classes of deviation from the reference release moment were determined according to the international equipment safety requirements from ASTM F1063-03, ASTM F1064-03, ASTM F939-06, ISO 13993: 2001, and ISO 11088-2006 (E). A randomly chosen sample of 9 % (124 skis/62 pairs) of S-B-B systems from the total ski rental fleet was tested using a Wintersteiger calibration machine. There were a high percentage of Class I deviations in the rental fleet: 50 % (2 seasons), 95 % (3 seasons), and 64 % (4 seasons). Class 1 deviations do not require corrective action; however, increased sampling is indicated. Based on the high percentage of Class I deviations the entire fleet should be inspected. Class II deviations that required immediate corrective action were found in 48 % of the S-B-B with two seasons of use. Only 8 % of the rental fleet had Class III deviations warranting removal from the rental fleet. The heel-pieces of S-B-B systems that had two or more seasons of use were nine times more likely to be out of tolerance than those with only one season of use; however, there was only a small increase in the proportion of toe-pieces out of tolerance for older compared to newer S-B-B systems. These differences may be due to age or to different models of S-B-B systems. The policy of retiring ski rental equipment after three or four seasons of use appears to be inadequate to ensure the supply of safe equipment. Language: en
