GB/T 40934-2021 《Rotational moulding—Test method for powder flowability》 Related products
This standard specifies a test method for the fluidity of powder used in rotational molding, which is applicable to powder materials in rotational molding processes. By measuring the apparent density (pb) and outflow time of the powder, its suitability and process performance are evaluated to provide a basis for material selection and production processes.
