  • Publication number: 20210041334
    Abstract: The invention relates to a test apparatus and a method for testing a load change of a compressed-gas accumulator, said method comprising the steps of: i. arranging the compressed-gas accumulator to be tested inside a test container; ii. increasing the pressure of a compressed gas in the compressed-gas accumulator to a test pressure; iii. measuring the elastic deformation of the compressed-gas accumulator, which is caused by the test pressure of the compressed gas; iv. Increasing the pressure of a pressure medium in the test container such that the elastic deformation of the compressed-gas accumulator is reduced by the pressure of the pressure medium on the compressed-gas accumulator; v. lowering the pressure of the pressure medium in the test container; and vi. repeating steps iii. to v.
