Covers specifications and test methods for unused mineral insulating oils, as delivered, intended for use in cables with oil ducts. These include hollow core cables, pipe type cables and any others in which provision is made for the oil to flow. Supersedes IEC 60465 (1974) and its first supplement 60465A (1977).

Defines the various terms employed in the calculation of metered petroleum quantities. Also specifies the equations which allow the values of correction factors to be computed. Also gives rules for the sequence, rounding and significant figures to be employed in a calculation. Provides tables which may be used to look up specific correction factors should it not be desired to calculate them by manual as well as computer methods. The field of application is the volumetric measurement of liquid hydrocarbons, including liquefied petroleum gases, by meter and prover. It does not include two-phase fluids.

Gives a method for the determination of acidic constituents in products soluble or nearly soluble in mixtures of toluene and propan-2-ol. It is applicable for the determination of acids whose dissociation constants in water are greater than 10-9. The method may be used to indicate relative changes that occur in an oil during use under oxidizing conditions regardless of the colour or other properties of the resulting oil. No general relationship between bearing corrosion and acid or base numbers is known.

Provides guidance for the design, installation and calibration of these provers. Calculation techniques for use when calibrating and operating provers are detailed in ISO 4267-2. Most of the material is general in that it applies to provers for use with different liquids and types of meters and for proving them in different services. Does not apply to the newer "small volume" or "compact" provers.

Procedure given applies to gases, such as propane, butane or mixtures thereof. It is suitable for sampling into containers to provide samples for laboratory testing of products covered by ISO 9162. Although this procedures can be used to provide samples for compositional analysis, it is strongly recommended that alternative apparatus, such as a variable-volume container, be used to minimize compositional changes that may occur.
