→2000N wave spring elastic test: place the wave spring between two parallel plates of the testing machine and gradually apply load so that the distance between the two parallel plates reaches the test height specified by the wave spring, and measure the elasticity at this time. Then continue to increase the load of the corrugated spring which is proved to be qualified in elasticity test, so that the distance between the two parallel plates can reach the nominal value of corrugated spring H /3, and keep the load for 24h. Release the load and do the elastic test again.The elasticity of the corrugated spring shall be no less than 90% of Fmin after the elastic test.
