桌子測試儀器                                            

測試項目：桌子的穩(wěn)定性和桌面沖擊。                      

1、  垂直負(fù)載下的穩(wěn)定性試驗：

Stability test of the vertical load

把試件放在試驗基面上。在其*不穩(wěn)定桌邊中心離邊沿向內(nèi)50mm桌面處通過加載墊垂直向下逐漸加力到規(guī)定的力值或者至少試件至少有一個桌腳離地為止。

Place test specimen on the base surface. Impose the force to the table in its center from the edge of the most unstable inward 50mm desktop vertically down through the loading pad gradually with augmented the value or at least one specimen legs up off the ground.

2.垂直和水平加載穩(wěn)定性試驗：

Vertical and horizontal load stability test

把試件放在試驗基面上。用擋塊擋住試件*不穩(wěn)定邊的桌腳。防止試件在試驗中移動。在該邊中心離邊沿向內(nèi)50mm桌面處通過加載墊垂直向下施加100N的力。同時在該邊中心桌上向外施加一個水平力。逐漸增加該力到規(guī)定值或者至少有一個桌腳離地為止。

Put the specimen on the test-based surface. With the block blocking the most unstable side of the specimen legs to prevent the test specimen to move. The edge center from the edge inward 50mm desktop department ，exert downward vertical 100N force by loading pad. While exert a level force on the center desk of the edge, increase gradually to a specified value or one leg near to the floor at least.

3.垂直靜載荷試驗：

Vertical static load test

在桌面易于發(fā)生破壞的位置，按規(guī)定的力通過加載墊，垂直向下重復(fù)施加10次。每次至少應(yīng)保持10秒。

On the most easy damaged position of the desk surface , to impose the specified force by loading pad, vertical put down repeated 10 times. Keep 10 seconds at least.

Desktop sustained vertical load test

椅子測試儀器                                        

測試項目：座面沖擊                                 

座面的沖擊試驗：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.
