ISO 4266-2:2002 (R2016)

ISO 4266-2 gives guidance on the accuracy, installation, calibration and verification of automatic level gauges (ALGs), both intrusive and non-intrusive, for measuring the level of petroleum and liquid petroleum products having a Reid vapour pressure less than 100 kPa, transported aboard marine vessels (i.e. tankers and barges). ISO 4266-2 gives guidance for buyers and sellers who mutually agree to use marine ALGs for either fiscal and/or custody transfer applications. ISO 4266-2 is not applicable to the measurement of level in refrigerated cargo tanks.
