ASTM D Ash Content. The purpose of this test is to determine the inorganic content of plastics. There are two methods described: Procedure A, Muffle. Reprinted from the Annual Book of ASTM Standards. This standard is issued under the fixed designation D ; the number immediately following the. This test method was developed to determine the inorganic content of plastics by destructive ashing procedures. Ash levels of % or above are covered.

Ash levels of 0. Samples are flamed over a burner prior to being ashed in a muffle furnace.

Test Method D is astk for unknown samples, and in instances where fusion of the inorganic portions may be of concern. Samples are flamed over a burner prior to being ashed in a muffle furnace.

Work Item s – proposed revisions of this standard. Typically the average of 3 crucibles is reported. To request a quote for this test or others Click Here. An Ash test is used to determine if a material is zstm. See Section 9 for specific precautionary statements. For more efficient ashing, the plastic sample should be in the form of powder or pellet.

The quantitative amounts of each asttm important variables of the manufacturing process. Due to copyright restrictions, we are not able to provide copies of standards. This standard does not purport to address all of the safety concerns, if any, associated with its use. It cannot identify individual percentages in multi-filled materials without additional test procedures being performed. Standards can be obtained from appropriate standards authorities.

ASTM D – ASH CONTENT (METHOD B)

Active view current version of standard. Test Method D is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern.

An ash test cannot be used to determine the percent carbon fiber or percent carbon black since carbon burns off during the Ash test. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Number of specimens tested by PTLI: Samples are ignited and ashed in a muffle furnace.

The test will identify the total filler content. A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of both. Note 1 — For more efficient ashing, the plastic sample should be in the form of powder or pellet. See Section 9 for specific precautionary statements.

Ash Content

Note 2 — This test method provides consistent results of filler content for a specific filler in a specific resin. Historical Version s – view previous versions of standard. Identification of Filler If the supplied material has mineral filler an FTIR analysis of the ash residue can help to further asrm the type of mineral. D56630 grams of sample is typically used, which represents three crucibles each containing two grams of sample. TGA Thermogravimetric Analysis is an alternative method to determine filler content with smaller samples sizes.

However, this method may not provide the absolute astk content in all cases. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes.
