座椅座面的试验方法
Test Method for Seat Chair and seatsurface:
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 theload point and keep at least 10 seconds. And repeated 10times
2.座面的疲劳试验：通过载入垫，将950N的力和规定的次数垂直向下重复施加在座面载入点上。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 thespecified times to repeat vertically down impose to the load pointof the seat surface. Loading rate no more than 40 times perminute
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，冲击载入部位各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 makeit fall freely. impact loading site 10 timeseach.
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载入点上。再将规定的力沿着与椅背垂直的方向通过载入垫施加于载入点上。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 chairleg. Then impose the specified balance loading to the load point ofthe seat. And then provides the force perpendicular to thedirection along the back pad by loading imposed on the load point.To keep at least 10 seconds each. And repeated 10times.
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载入点上，再通过椅背载入块，将330N的力按规定的次数施加在椅背的载入点上。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 thechair and then impose the 950N force vertically to the surface loadpoint, through the back loading block. Impose 330 N force withspecified times to the back loading site. Loading rate no more than40 times per minute.
桌子测试仪器
测试项目：桌子的稳定性和桌面冲击。
1、 垂直负载下的稳定性试验：
Stability test of the vertical load
把试件放在试验基面上。在其*不稳定桌边ZX离边沿向内50mm桌面处通过载入垫垂直向下逐渐加力到规定的力值或者至少试件至少有一个桌脚离地为止。
Place test specimen on the base surface. Impose the force to thetable in its center from the edge of the most unstableinward 50mmdesktop vertically down through the loading pad gradually withaugmented the value or at least one specimen legs up off theground.
2.垂直和水平载入稳定性试验：
Vertical and horizontal load stabilitytest
把试件放在试验基面上。用挡块挡住试件*不稳定边的桌脚。防止试件在试验中移动。在该边ZX离边沿向内50mm桌面处通过载入垫垂直向下施加100N的力。同时在该边ZX桌上向外施加一个水平力。逐渐增加该力到规定值或者至少有一个桌脚离地为止。
Put the specimen on the test-based surface. With the block blockingthe most unstable side of the specimen legs to prevent the testspecimen to move. The edge center from the edgeinward 50mmdesktop department ，exert downward vertical 100N force by loadingpad. While exert a level force on the center desk of the edge,increase gradually to a specified value or one leg near to thefloor at least.
3.垂直静载荷试验：
Vertical static load test
在桌面易于发生破坏的位置，按规定的力通过载入垫，垂直向下重复施加10次。每次至少应保持10秒。
On the most easy damaged position of the desk surface , to imposethe specified force by loading pad, vertical put down repeated 10times. Keep 10 seconds at least.
Desktop sustained vertical load test
