Natural gas — Coal-based synthetic natural gas quality designation and the applicability of ISO/TC 193 standards

This document introduces the production process, the distribution and quality designation of coal-based synthetic natural gas (CBSNG) in many places around the world, and examines whether ISO/TC 193 standards for sampling, test and calculation methods are applicable to the CBSNG product.
