(1)密度
JIS K2249に従って測定した。
JIS K2283に従って測定した。
JIS K2269に従って測定した。
JIS C2101に従って測定した。
JIS K2541に従って測定した。
JIS K2609に従って測定した。
ASTM D2007に従って測定した。
JIS C2101に従って測定した。
空気雰囲気下において、供試油1000 gを触媒の銅線(直径1 mm、長さ3.5 m)と共に120℃で168時間保持して、劣化油を調製し、劣化後の帯電度を測定した。なお、帯電度は、ミニスタティックテスタ(IEEE Transaction on Power Apparatus and Systems, PAS-103, 1923 (1984))により測定した。
JIS K2265に従って測定した。
JIS K2254に従って測定した。
以下に示す方法により定量した。通常使用される薄層クロマトグラフィー用の薄層板(例えば、ガラス板に0.25 mm程度の厚さにシリカゲルを塗布したもの)に塩化パラジウム0.5質量%の塩酸酸性アセトン−水混合液を噴霧し、風乾後に試料油の2〜4μLをスポット点着し、四塩化炭素液により点着位置より約10 cm展開させた後、クロロホルム/メタノール(容積比9/1)混合液でさらに約5 cm展開する。この操作によりスルフィドの形態の硫黄化合物は、炭化水素及び他の有機硫黄化合物と分離し黄色の発色スポットを示す。該発色スポット部にデンシトメータ(例えば、島津製作所製、2波長クロマトスキャナーCS−910型)で380 nmの可視光をあて吸光度を求める。試料油を測定する際にスルフィド形態硫黄濃度既知の試料を同時に展開し、同様の測定を行う。これにより試料中に含有されるスルフィド形態の硫黄分が定量される。なお、スルフィド形態の硫黄分は、下記一般式(1):
R1−S−R1 (1)
[式中、R1は、それぞれ独立して炭素数10〜15のアルキル基又は芳香族炭化水素基を表す]、又は下記一般式(2):
[式中、Rは、それそれ独立して水素原子又はアルキル基を表わし、Rが複数存在する場合、各Rは同一でも異なってもよい]で示される有機硫黄化合物を構成している硫黄の総量である。
