Annex A (normative) Specification of the test rig
Annex B (normative) Measuring equipment used to determine the
                    evaporation coefficient of LNG in
                    contact with the insulating lining
Annex C (normative) Method of calculation of the evaporation
                    coefficient of LNG in contact with the
                    insulating lining
