N15(H) oil, crude: naphthenic, viscosity (40 ☌): 15 mm 2/s, hydrotreated (catalytic hydrogenation)Įstablished by the Committee at its forty-fourth meeting P15(H) oil, crude: paraffinic, viscosity (40 ☌): 15 mm 2/s, hydrotreated (catalytic hydrogenation N70(H) oil, crude: naphthenic, viscosity (40 ☌): 70 mm 2/s, hydrotreated (catalytic hydrogenation P70(H) oil, crude: paraffinic, viscosity (40 ☌): 70 mm 2/s, hydrotreated (catalytic hydrogenation) P70 oil, crude: paraffinic, viscosity (40 ☌): 70 mm 2/s P100 oil, crude: paraffinic, viscosity (40 ☌): 100 mm 2/s For the purpose of characterization of the different types of oils and waxes, the criteria viscosity, average relative molecular mass and carbon number at 5% distillation-point were used in the specifications (see Table 1). The latter group was furthermore divided into three classes. In order to define the materials more clearly, the Committee at its forty-fourth meeting (Annex 1, reference 116) prepared individual specifications for micro-crystalline wax and for two groups of mineral oils: mineral oils (high-viscosity) and mineral oils (medium- and low-viscosity). Mineral oils (medium- and low-viscosity) are mixtures of highly refined paraffinic and naphthenic liquid hydrocarbons with boiling-points greater than 200 ☌. They are manufactured from crude mineral oils in various refining steps, such as distillation, extraction and crystallization, and are subsequently purified by acid treatment (oleum method) and/or hydrotreatment (catalytic hydrogenation). Mineral oils (medium- and low-viscosity) comprise a subgroup of the family of mineral oils and waxes.
