This standard specifies the methods for determining the cleanliness of foundry machinery, including the weight method and the microscope method. It is suitable for testing the cleanliness of foundry machinery. Cleanliness is defined as the amount of solid contaminants in foundry machinery. These contaminants may include metal chips, sand, dust, fibers, etc., which may negatively affect the working performance, life and Reliability of the machinery. The weight method is introduced in the standard. Cleanliness is evaluated by measuring the weight value of contaminants. Microscope law is divided into particle counting method and particle comparison method. The former uses Microscope to determine the amount of contaminants, and the latter determines cleanliness by comparing with standard samples. These methods provide a scientific basis for ensuring the cleanliness of foundry machinery.
