Description
キセノン色調変化試験は、スガ試験機株式会社製のスーパーキセノンウェザーメーター(SX75)を用いて、キセノン照射前後でのボール表面の色の変化をスガ試験機(株)製の色差計(型式SC-P)を用いて測定し、JIS Z 8701のLab表色に基づき、照射前と照射後のボールの黄変に対する変色性(色差ΔE)を調べた。なお、色差ΔEは、値が小さいほど変色が少ないことを示す。また、色差ΔEから黄変を評価した。評価基準は、色差ΔEが6.5以下の場合に◎と評価し、6.5超10.0以下の場合に○と評価し、10.0より大きい場合に×と評価した。
キセノン黄色度変化試験は、色差計(スガ試験機株式会社製の分光測定機SC-P)を用い、JIS Z 8722「反射物体の測定方法」(拡散光照明、8度受光の光学系:条件c)に準拠し、d/8(試料の正反射成分を含まないで測定:光トラップあり)により測定した。測定孔径はφ30mmを使用した。そして、キセノン照射前後のボール表面を、JIS Z 8701のLab表色に基づきL、a、bの各値、および黄色度YIを測定し、照射前と照射後の差(黄変度ΔYI)を求めた。
