What is BS 5131-3

Natural gas. Measurement of properties. Volumetric properties: density, pressure, temperature and compression factor included-in-kit a) chemical substances which are1 Scope This international Standard gives requirements and procedures for the measurement of the properties of natural gas that are used mainly for volume calculation and volume conversion: density at reference and at operating conditions, pressure, temperature and compression factor. Only those methods and instruments are considered that are suitable for field operation under the conditions of natural gas transmission and distribution, installed
