1、BS EN 957-7Stationary training equipment - part 7: rowing machines, additional specific safety requirement and test methods静态型健身器材划船器的附加平安要求和测试方法Apr 28th, 2006Jerry YinBS EN 957-7 Presentation EN957-7演示This part of EN957 specifies safety requirements for rowing machines in addition to the generalsaf

2、ety requirements of EN957-1 and should be read in conjunction with it.This part of EN 957 is applicable to stationary training equipment type rowing machines If accessories are provided with the rowing machine for the performance of additional exercise these are subjected to requirements of EN 957-1

3、 and any other specified requirements of theappropriate part of this standard.EN957的这个部分规定了划船器的安全要求,它是EN957-1的一个补充,应该与EN957-1一同阅读.EN957的这个部分适用于静态型的划船器,如果与划船器一起提供了相关的附件以便进行附加的性能测试, 那么这些部分应该满足EN957-1和这份标准中的任何其他相关要求5 Safety requirements 安全要求5.1 General概要The following requirements shall apply as appropr

4、iate以下的安全要求应该得到满足。5.2 External construction 外部结构5.2.1 Squeeze and shear points within the accessible area 可接触区域的剪切点The distance between movable parts and adjacent movable or rigid parts shall be at least 25 mm if relevant for fingers only, otherwise it shall be at least 60mm. Also other finger entra

5、pment danger should be extinguished.可移动部件和相邻的可移动部件或者是固定部件之间的间隙应至少大于60mm,如果这个间隙只是针对手指的话,那么这个间隙应该至少大于25mm. 其他的可能夹手指的间隙也应该消除掉. 如果这个夹手指的间隙在使用的整个过程中始终处在使用者的视线范围以内的话,那么这个60mm间隙就可以不受这个要求的限制5.2.2 Transmission elements and rotating parts传输和旋转部分Transmission elements, fans and flywheels shall be protected so t

6、hat the test finger can not be trapped.旋转的部分,比如风扇或者是飞轮等应该被保护起来以防止产生夹手指的间隙.5.2.3 Temperature raise 温升Operating the rowing machine for 20 min at the stipulated value according to Clause 6.4 after the completion, the temperature of accessible parts shall not exceed 65C.当按照条款6.4进行20分钟测试之后,划船器可接触区域的温度不可以

7、超过65C.条款6.4: 以每分钟25次的频率,作用350N的力在把手上,要求运动的行程超过60%的情况下运行20分钟,之后测量可接触区域的温度。5.2.4 Seats 座椅Apply a test force of 100N for 1 min to all directions of the seat. The seat shall not derail.在座椅上向任何方向施加一个100N的力,维持一分钟,座椅不可以发生脱轨.10Kg10Kg5.3 Intrinsic loading 内部载重测试Apply a test load of 250Kg for class H and 300K

8、g for Class S to the seat for 5 min, after remove of the test load, the deformation of the seat shall not exceed stipulated values针对家用型的划船器在座椅上施加一个250Kg的力,针对专业型的划船器在座椅上施加一个300Kg的力,维持5分钟, 移走测试的力之后,检查座椅的变形量有没有超过规定的值.250Kg5.4 Handles 把手In rowing machines where the handle is connected to the machine by

9、a flexible member (rope belts or chains), the mass of the handle without a flexible member shall 600g当把手是通过一个活动的部件(比如绳子或者是链条等)连接到划船器上的时候，那么，这个不包含活动部件的把手的重量不可以超过600克。5.5 Foot supports and foot straps 脚部支持和脚部绑带Provisions shall be made for fastening the foot (foot straps). The foot strap shall be able

10、to withstand a test force (500N for H and 1000N for S) to the center of the foot strap at right angles to the foot supports for 1 min without breakage.Each foot support shall withstand a test force of 1000N applied with a test device to the foot support without breakage应该提供一个装置来固定脚的位置，比如脚带等。 在脚带的中心位

11、置在正常使用方向施加一个50公斤(家用型)的力，维持一分钟，要求脚带不发生损坏。 针对脚踏：使用一个凹状的测试块在脚踏板上施加一个100Kg的力，要求不发生损坏。50Kg5.6 Endurance test 疲劳测试60Kg test mass on the seat and 25cycles/min at a force which produces 200N at the handles and covers 75% to 80% of the full stroke range.For class H 12000 cycles for 15 min and rest 15min then

12、 continued the same patternFor class S 100000 cycles for 10h, cool down to room temperature and continue After the test the rowing machine shall still be functional.在划船器上放置60公斤的人体载重,以25次每分钟的频率运行划船器,要求其行程达到总行程的70%至80%. 同时要求测试时在把手上产生的力可以达到20KG.针对家用型的划船器,运行15分钟休息15分钟直到完成12000次疲劳测试.针对专业型的划船器,运行10个小时,冷却到

13、室温,继续运行10个小时直到100000次测试完成.5.7 Stability 稳定性 (测试图片参考EN957-5的测试图片)100Kg test person (1750mm) on the rowing machine, running the rowing machine at 35 strokes per min for both speed-independent and speed-dependent machines. Place the rowing machine on a 10 slope in the dynamic direction and on a 5 slope

14、 in all other directions for 1 min, the rowing machine shall not lift more than 10mm.在划船器上使用一个100公斤的人体载重(身高1750), 以35次每分钟的频率运行划船器,在动态方向将划船器放置在10斜台上，在其他的方向放置在5斜台上，维持1分钟,划船器不可以离地10mm. (测试图片参考EN957-1的测试图片)5.8 Additional requirements for class A 精确等级A类的附加要求The variation of the indicated or determined power P from the power input shall not exceed +/-5W up to 50W and +/-10% over 50W针对功率不超过50W的电动划船器, 规定的电源输入P的变化量不可以超过+/
