GB/T 13465.7 - 2009 specifies the test method for the weight gain rate and hole filling rate of impermeable graphite. It requires the selection and preparation of the sample to ensure that it can represent the characteristics of the product. Detail the test equipment, such as weighing instrument accuracy, soaking vessel specifications, etc. In terms of operation, standardize the soaking medium, soaking time and weighing process. Through this standard, the weight gain and hole filling degree of impermeable graphite after specific treatment can be accurately determined. This is essential for evaluating the mass of impermeable graphite products, controlling the production process and its application in chemical industry, environmental protection and other fields, helping enterprises to improve product performance and meet actual use needs.
