The main standards for testing washing machine shock absorbers include the three core standard systems of QB/T 4996-201, GB/T 4288-2018, and IEC 60456.
GB/T 4288-018 "Electric Washing Machines for Household and Similar Use" is the national standard for washing machine products, and Section 5.15 specifically stipulates the requirements for vibration performance, and Appendix J details the test methods for the vibration performance of washing machines. This standard requires that the overall vibration amplitude of the washing machine should not exceed mm when running at high speed, and clearly defines the measurement methods for physical quantities such as vibration acceleration, velocity, and displacement.
IEC 60456Methods of Performance Measurement for Household Washing Machines" is an international standard issued by the International Electrotechnical Commission, with the latest version being IEC 6046:2024 released in 2024. This standard specifies the performance measurement methods for household washing machines, including vibration performance testing. Compared to the previous version the new standard introduces new measurement and evaluation methods, adds descriptions of washing machine loads, and expands the test methods.
