椅子測試儀器
測試項(xiàng)目：座面，靠背。
座椅座面的試驗(yàn)方法
Test Method for Seat Chair and seat surface:
1.座面的靜載荷試驗(yàn)：通過加載塊垂直向下施加一定力量于加載點(diǎn)上并保持至少10秒。并反復(fù)進(jìn)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.座面的疲勞試驗(yàn)：通過加載墊，將950N的力和規(guī)定的次數(shù)垂直向下重復(fù)施加在座面加載點(diǎn)上。加載速率為每分鐘不超過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.座面的沖擊試驗(yàn)：將一塊泡沫塑料放在座面上，然后把座面沖擊器置于規(guī)定的高度，使其自由跌落，沖擊加載部位各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.
座椅靠背的試驗(yàn)方法：
Test methods for back of the chair
1.座背的靜載荷試驗(yàn)：用擋塊靠住椅和凳子的腳上。然后將規(guī)定的平衡載荷施加于座面加載點(diǎn)上。再將規(guī)定的力沿著與椅背垂直的方向通過加載墊施加于加載點(diǎn)上。每次至少保持10秒。并反復(fù)進(jìn)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.座背的疲勞試驗(yàn)：用擋塊靠住椅或者凳子的腳上，然后將950N的力垂直施加在座面加載點(diǎn)上，再通過椅背加載塊，將330N的力按規(guī)定的次數(shù)施加在椅背的加載點(diǎn)上。加載速率為每份鐘不超過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.
