Description
得られた加硫ゴム試験片を偏平円柱状の台ゴムに貼り付け、インサイドドラム型氷上摩擦試験機を用いて、測定温度−1.5℃、荷重5.5kg/cm2、ドラム回転速度25km/hの条件で氷上摩擦係数を測定した。得られた氷上摩擦係数を、標準例の値を100とする指数にして、「氷上性能」の欄に示した。この指数値が大きいほど氷上摩擦係数が大きく氷上性能が優れることを意味する。
得られた加硫ゴム試験片を使用し、JIS K6253に準拠しデュロメータのタイプAにより−10℃でゴム硬度を測定した。得られた結果は、標準例の値を100にする指数として「ゴム硬度(−10℃)」の欄に記載した。この指数が小さいほど、低温時のゴム硬度が低く、しなやかで低温性能が優れることを意味する。
