Testing has been executed according to Shell Mesc 77/300 (Procedure and technical Specification for Type Acceptance Testing [TAT] of industrial Valves); leakage and fugitive emissions tests, in particular, have been conducted on the minimum and maximum valves’ designated temperature ranges.

A gas burner has been used fot the high temperatures measurements (> 300 °C); to reproduce the low temperature phases (-50°C),  liquid nitrogen’s evaporation has been used.
