Description
〔引張り試験〕(参照:ASTM D 882)
この方法によって、さまざまな弾性材料の引張り強さおよび伸び率を測定する。明確に定義された試験片の引張り強さおよび伸び率を、引張り試験機を用いて検査する。
・コンピュータに接続された引張り試験機
・クロスヘッド速度:500mm/min
・クランプ距離:50mm
・最大力における伸び率、%
・破断力、N/25.4mm
・破断力における伸び率、%
・ニーポイント N/%
この方法は、繰り返される負荷および除荷サイクルにおいて弾性材料がどのように反応するかを測定する方法に関するものである。試料があらかじめ決められた伸び率で伸長させられ、そして0とあらかじめ決められた伸び率との間での周期的に作動するように実施される。所望の負荷および除荷の力を記録する。弛緩状態の材料の、持続的な(すなわちそのままの状態の(remaining))伸び率を測定する。
・クロスヘッド速度: 500mm/min
・クランプ距離: 50mm
・予荷重: 0.05N
耐破壊性は、ASTM等級D3763-02に基づいて測定される。貫通衝撃型試験に基づいて、この方法によって変位に対する荷重のデータが得られる。各試料の最大荷重が算出される。
