ASTM D1621 刚性多孔塑料的压缩性能
ASTM D1621-04a标准规定了刚性多孔材料尤其是泡沫塑料的压缩性能测试条件。刚性泡沫材料通常用于建筑工业做为隔音、隔热材料,依照此标准需要测定的数据包括屈服点,压缩强度与压缩模量。
适合于该应用的测量系统包括3300和5500系列电子万能试验机并配备压缩平台。压缩平台的平行度非常重要,因此建议使用球型座台式压缩平台且配备刚性平台。该套配件自我对位功能将使平台与试样之间的接触面积达到最大化,旋转座台可以置于平台上安装在设备底座或与移动横梁上的载荷传感器相联。为了减少可能产生的偏心负载影响,通常将旋转座台置于底座。
如果使用两个刚性压缩平台,建议使用应变计装置,例如线性变化差动变压器(LVDT),以便把由于系统柔度产生的误差最小化。然而,假如你使用Bluehill®软件结合负载框架柔度修正计算,则不需要挠度计,除非测试标准有要求。
为了让测试简单化,在试样之间保持10到30 mm间距可以快速而地容易拆去测试过的试样并安装新试样。Bluehill预载功能自动移动上压缩盘直至以预设的载荷接触试样,此预载功能减少操作员的工作量,节省时间且提升准确性.
