The ISO 1522-2022 standard specifies the pendulum damping test methods for Paints and varnish, including the König and Persoz pendulum tests. These tests are used to assess the degree of drying and hardening of the Coating, and the method is based on the oscillation damping of the pendulum on film. The standard details the operating principles, measurement requirements, and test conditions for both pendulums. Major updates include the addition of term definitions, adjustments to swing and time tolerances, and amendments to the pendulum accuracy statement. The testing process should be carried out in a temperature and Humidity controlled environment to ensure accuracy and conformity of the results.
