10kN電炭制品抗折強度試驗機,依據JB/T 8133.7-2013和JB/T 8133.1-2013設計制作,測定電炭制品折斷時載荷,計算抗折強度。HRJ Tester;檢查試樣尺寸,對尺寸w和b測量准確度爲0.5%,將試樣對稱放置于兩支承刀口上,尺寸L垂直于刀口,尺寸w平行于刀口,負荷壓頭在試樣中間加壓,啓動抗折強度試驗機,均勻緩慢加載,時間不少于5s,直至試樣斷裂,讀取此時破壞力F,按公式計算電炭制品抗折強度。
JB/T 8133.1-2013電炭制品試樣加工技術規定:電炭制品抗折強度試樣10x10x64mm或4x8x32mm。64mm/32mm必須垂直于模壓制品壓力方向,平行于擠壓制品軸線方向。HRJ Tester;厚度必須平行于壓力方向。b和w偏差±0.04mm,L尺寸偏差0.8mm,bxW爲正方形,角度偏差±1.5°,垂直于L尺寸的任何橫截面的兩對面平行度公差爲0.04mm。抗折強度試驗負荷壓頭刀口半徑r1=4.5mm±0.5mm,支承刀口半徑r2=1mm±0.5mm。
