Description
CD引張り強度試験方法
当業者に理解されるように、EDANA 20.2−89を用い、サンプル幅50mmかつ評点距離100mm、前負荷0.1ニュートンかつテストスピード100mm/分にて横断方向引張り強度を測定できる。特に、この試験方法を用いてピーク力時横断方向引張り強度を測定できる。
当業者に理解されるように、ネックダウン係数を様々な方法で測定できる。つまり、正確で一貫した結果を導ける1つを超える測定方法がある。以下には、本開示の結合ウェブにおいてネックダウン係数を測定する1つの方法について示す。本ネックダウン係数測定法を図30〜34の実施形態に関連して説明し、図示する。
