Publication date:   Aug 6, 2026

Scope

This document specifies a method for determining the phase equilibrium point of natural gas hydrates in a laboratory setting under constant volume conditions, including the principle, reagents and materials, apparatus, procedure, expression of results, test report and precision.
This document applies to laboratory simulations of hydrate formation and decomposition processes. It involves the analysis of collected temperature and pressure data to determine the phase equilibrium temperature of hydrates.
