This standard specifies the method for determining the ash content in coal-based granular activated carbon. The core principle involves weighing a certain amount of the sample, placing it in a high-temperature muffle furnace, igniting it at a specific temperature (e.g., 815±10℃) until constant weight is achieved, and calculating the mass fraction of ash based on the mass difference before and after ignition. This method is applicable to all types of coal-based granular activated carbon. The key instruments required for performing this test are an analytical balance and a box-type resistance furnace (muffle furnace). The standard provides detailed procedures for drying, carbonization, ignition, and cooling.
