The invention belongs to the technical field of sampling efficiency tests, and particularly relates to a test method for determining aerosol sampling efficiency of a sampling pipeline. The method comprises the following steps: 1, building a test platform according to the design of a sampling system; 2, generating particles meeting the particle size; 3, setting a flow velocity and air pressure test according to the operation conditions of the sampling system; 4, testing the sampling efficiency of each sampling part; 5, measuring the sampling efficiency value of each sampling part; and 6, determining an integrated sampling efficiency value of the sampling system. Based on sampling system components actually used on site and arrangement, the sampling efficiency test platform is built in a laboratory, the test process is simplified, uncertain factors in modeling or theoretical calculation are eliminated, and the accuracy of obtaining aerosol sampling efficiency values is improved.
