The invention discloses a method for testing the hydrophilia of a panel reverse osmosis membrane. According to the method, pretreatment comprises the steps of immersing the reverse osmosis membrane in pure water at the indoor temperature, washing the reverse osmosis membrane with the pure water, and carrying out vacuum drying on the reverse osmosis membrane to be prepared for use; regulating and controlling the relative humidity of the environment, test temperature and the salinity of a test solution; laying the membrane flat and sticking the membrane to a sample table of a contact angle analysis meter with a separation layer facing upwards and a supporting layer in contact with the sample table. The test is conducted with the static contact angle method, a small pure water or salt water drop is dripped onto the membrane after parameter setting of the contact angle analysis meter is regulated, a static diagram of the liquid drop can be obtained after the liquid drop is balanced on the membrane, and analysis and contact angle calculation are carried out on the static diagram of the liquid drop by means of liquid drop shape analysis software; the operation is repeated multiple times on different positions of the membrane, and an average value is obtained as the final contact angle result. According to the method for testing the hydrophilia of the panel reverse osmosis membrane, the pretreatment method of the testing process is defined, the concept that three testing conditions need to be controlled and defined is proposed, the reliability of the hydrophilia detecting method and the comparability of the detecting result are improved, and repeatability is high.
