GB/T 7994.1-2014 "Test Methods for Glass-lined Equipment—Part 1: Hydrostatic Test" specifies the requirements, methods, and procedures for hydrostatic tests and combined gas-liquid pressure tests of glass-lined pressure equipment, applicable to glass-lined pressure vessels. Clean water is injected into the equipment, and air is completely expelled. The pressure is then gradually increased to the test pressure and maintained for a specified duration to check for leaks, deformations, and abnormal noises. The test requires equipment such as high-pressure water pumps, precision pressure gauges, thermometers, and timers, used to verify the pressure-bearing capacity and sealing integrity of the equipment.
