The functions, principles and failure modes of a hatch for manned spacecraft were presented. Reliability characteristic parameters of the hatch was given. Based on the thought of measurement for characteristic parameter of the hatch, the reliability verification test method was put forward, including test method, test state, test program, failure criterion and reliability assessment method. An application example of the method was shown. By these methods, the reliability of the hatch for manned spacecraft could be verified.
