This part of ISO 20088 describes a method for determining the resistance to cryogenic spray on Cryogenic Spillage Protection (CSP) systems. It is applicable where CSP systems are installed on carbon steel and will be in contact with cryogenic fluids.Liquid jet release is potentially formed at high pressure LNG handling section in LNG liquefaction unit, e.g., around 40 - 60 bar operating pressure. Due to high velocity discharge, it may cause severe condition for cryogenic protection coating by large momentum with extreme cryogenic temperature.Liquid nitrogen is used as the cryogenic medium since it has a lower boiling point than liquid natural gas or liquid oxygen and it is not flammable. Additionally, it can be safely used for experiment.Part 2 of the standard covers vapour phase exposure conditions.The test laboratory is responsible to conduct an appropriate risk assessment according to local regulation in order to consider the impact of liquid and gaseous nitrogen exposure to equipment and personnel.
