上記実施例及び比較例の電線試験サンプルについて、次の方法により高温摩耗性及び低温性の評価を実施した。各評価結果を表1乃至表4に合わせて示す。
上記で得られた各例の電線試験サンプルに対し、摩耗子として直径0.45±0.01mmの針金を用い、IS06722:2006のスクレープ摩耗規格に準拠して、摩耗試験を実施した。なお、この試験では、100±1℃の雰囲気下、5±0.05Nの荷重を電線試験サンプルにかけた状態で、摩耗子を絶縁被覆層上で繰り返しスライドさせた。そして、スクレープ回数が5回以上でも金属導体と針金との間で導通しなかった場合を「○」と評価し、スクレープ回数が5回未満で導通した場合を「×」と評価した。
まず、実施例及び比較例で得られた電線試験サンプルを、空気中、−40℃の環境下で4時間以上冷却した。次に、当該電線試験サンプルの直径と同じ直径を有する金属マンドレルへ、冷却後の電線試験サンプルを螺旋状に巻き付けた。その後、巻き付けた電線試験サンプルの金属導体と金属マンドレルとの間に1kVで1分間の耐電圧を印加した結果、絶縁破壊が発生しなかったものを「○」と評価し、絶縁破壊が発生したものを「×」と評価した。
