（GB/T6670-2008 ISO8307 ASTM D3574 ISO8307）軟質(zhì)泡沫聚合材料落球法回彈性能的測定

（GB/T6670-2008 ISO8307 ASTM D3574 ISO8307） determination method of falling ball rebound performance soft foam polymerization

二、適用范圍及功能：

Two, applicable scope and functions:

適用于測定軟質(zhì)聚氨酯泡沫塑料的落球式回彈性能.

Suitable for performance ball rebound fell determination of soft polyurethane foam.

落球回彈是通過給定直徑和質(zhì)量的鋼球在規(guī)定高度上自由落在泡沫塑料試樣上，計(jì)算鋼球回彈的zui大高度與鋼球落下高度比值的百分率既回彈率，以回彈率表示泡沫塑料的回彈性能。滿足08標(biāo)準(zhǔn)A法和B法試驗(yàn)方法。主要是測試塑料泡沫材料及海綿材料的回彈性能。 

Ball rebound is given through the steel ball diameter and quality in the specified height of free fall on the foam specimen, the maximum height calculation of ball rebound the ball falling height and the percentage of both resilience, said resilient properties of foam to rebound rate. To meet the 08 Standard Test Method A method and B method. Mainly rebound performance test of plastic foam material and the sponge material.

落球回彈測量精度高采用微處理器進(jìn)行控制，中文顯示，并可打印試驗(yàn)數(shù)據(jù)。

Ball rebound high measurement precision by using microprocessor to control, Chinese display, and print the test data.

五、試驗(yàn)步驟：

Five, the test procedure:

將調(diào)節(jié)后的試樣水平置于回彈儀的測試位置上，通過調(diào)節(jié)使鋼球底部從固定位置到泡沫塑料表面的落下高度為460mm。在釋放裝置上固定鋼球，然后使鋼球自由落下。對(duì)每一個(gè)試樣做三次回彈，取三次回彈中的zui大值。每次回彈鋼球應(yīng)落在試樣表面的同一位置上，并且兩次回彈的時(shí)間間隔應(yīng)控制在20s之內(nèi)。如果鋼球在回彈過程中碰到或彈出測量裝置，所得數(shù)據(jù)無效，需重新補(bǔ)做。

Will test the position of the sample placed horizontally on the rebound instrument adjusted by adjusting the ball on the bottom, from a fixed position to the foam surface fall height of 460mm. Fixed ball in releasing device, and then the ball free fall. Do three rebound on every sample, a maximum value of three rebound. Each time the rebound ball should be in the same position on the sample surface, and the two rebound time interval should be controlled within 20s. If the ball on the rebound process encountered or pop-up measuring device, the data is invalid, need to do.
