National annex
NA (normative) Measuring tapes

Specifies a method for the internal measurement of membrane tanks and independent prismatic tanks used in ships for the transport of refrigerated light hydrocarbon fluids. Sets out the calculation procedures for compiling the calibration table and correction tables to be used for the computation of cargo quantities. Coverage includes definitions, precautions, equipment, calibration procedure and calibration tables. Also includes annexes and diagrams. BS AMD 8897 RENUMBERS THIS STANDARD
