适用范围：This test method was developed to determine the inorganic content of plastics by destructive ashing procedures. Ash levels of 0.01 % or above are covered by this test method. These ashing procedures are used only to quantify the residual solids in the polymer and can not be used to identify the individual chemical components of the ash, qualitatively. This test method is limited to those materials (including glass) that are stable to 900?C. Test Method D 2584 is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern. Fluorinated polymers and polymers containing halogenated components have not been included in these procedures. Two procedures for determining the inorganic residue in plastics are listed as follows: Procedure A Muffle-Furnace Technique- For 5 - 50 gram samples. Samples are flamed over a burner prior to being ashed in a muffle furnace. Procedure B Rapid-Ash Muffle-Furnace Technique- For 5 - 50 gram samples. Samples are ignited and ashed in a muffle furnace. For more efficient ashing, the plastic sample should be in the form of powder or pellet. Note 1Procedure B is similar to ISO 3451/1-1981(E). The values stated in SI units are to be regarded as the standard. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See Section 9 for specific precautionary statements.
