Application Summary AI generated

This standard specifies the test method for evaluating the resistance of plastic-lined pressure vessels to negative pressure (vacuum) conditions. It is applied in the chemical and petrochemical industries to verify the structural integrity and adhesion of the plastic lining under internal vacuum loads, ensuring the vessel can withstand operational depressurization without delamination or collapse. The test is critical for quality control and safety certification of lined equipment used in corrosive fluid storage and processing.
