椅子测试仪器
测试项目：座面，靠背。
座椅座面的试验方法
Test Method for Seat Chair and seat surface:
1.座面的静载荷试验：通过加载块垂直向下施加一定力量于加载点上并保持至少10秒。并反复进行10次。
Seat Surface Static Load Test:
vertically down through the loading block to exert force on the load point and keep at least 10 seconds. And repeated 10 times
2.座面的疲劳试验：通过加载垫，将950N的力和规定的次数垂直向下重复施加在座面加载点上。加载速率为每分钟不超过40次。
Fatigue test of the seat: by loading pad, put 950N force and the specified times to repeat vertically down impose to the load point of the seat surface. Loading rate no more than 40 times per minute
3.座面的冲击试验：将一块泡沫塑料放在座面上，然后把座面冲击器置于规定的高度，使其自由跌落，冲击加载部位各10次。
Impact test of the seat: put a piece of foam on the seat surface, then place the impactor of the seat in a specified height and make it fall freely. impact loading site 10 times each.
座椅靠背的试验方法：
Test methods for back of the chair
1.座背的静载荷试验：用挡块靠住椅和凳子的脚上。然后将规定的平衡载荷施加于座面加载点上。再将规定的力沿着与椅背垂直的方向通过加载垫施加于加载点上。每次至少保持10秒。并反复进行10次。
Static Load Test for back of the chair: put the baffle on the chair leg. Then impose the specified balance loading to the load point of the seat. And then provides the force perpendicular to the direction along the back pad by loading imposed on the load point. To keep at least 10 seconds each. And repeated 10 times.
2.座背的疲劳试验：用挡块靠住椅或者凳子的脚上，然后将950N的力垂直施加在座面加载点上，再通过椅背加载块，将330N的力按规定的次数施加在椅背的加载点上。加载速率为每份钟不超过40次。
Fatigue test of the seat back : use the block fixed the feet of the chair and then impose the 950N force vertically to the surface load point, through the back loading block. Impose 330 N force with specified times to the back loading site. Loading rate no more than 40 times per minute.
