[0000] (13) Piercing Strength
【0040】
(13)突き刺し強度
[0074] A sample was prepared by cutting a film into a square of 50 mm in length×50 mm in width in the longitudinal direction and the width direction.
フィルムを長手方向および幅方向に長さ50mm×幅50mmの正方形に切り出しサンプルとした。
A piercing test was performed using a 0.5 mmφ needle at a crosshead speed of 5 mm/min using a tensile tester (Tensilon UCT-100 manufactured by Orientec Co., Ltd.), and piercing load and piercing displacement were measured.
引張試験機(オリエンテック製テンシロンUCT-100)を用いてクロスヘッドスピード5mm/分で0.5mmφの針を用いて突き刺し試験をおこない突き刺し荷重、突き刺し変位の測定を行った。
The measurement was performed five times each, and the average of the maximum piercing loads was adopted as the piercing strength of the sample.
各5回ずつ測定し、その最大突き刺し荷重の平均をサンプルの突き刺し強度として採用した。
The measurement was performed after controlling room temperature at 25° C. and 63% Rh. The obtained piercing strength was evaluated according to the following criteria.
なお、室温を25℃63%Rhに制御して行った。得られた突き刺し強度を、下記の基準で評価した。
