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.

Note 1 — For more efficient ashing, the plastic sample should be in the form of powder asgm pellet. Typically the average of 3 crucibles is reported.

An ash test cannot be used to determine the percent carbon fiber or percent carbon black since carbon burns e5630 during the Ash test.

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. Standards can be obtained from appropriate standards authorities. Work Item s – proposed revisions of this standard.

ASTM D – 06 Standard Test Method for Ash Content in Plastics

Identification of Filler If the supplied material has mineral filler an FTIR analysis of d5603 ash residue can help to further identify the type of mineral. Samples are flamed over a burner prior to being ashed in d560 muffle furnace. The quantitative amounts of each are important variables of the manufacturing process. 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. Samples are flamed over a burner prior to being ashed in a muffle furnace. However, this method may not provide the absolute filler content in all cases. Note 2 — This test method provides consistent results of filler content for a specific filler in a specific resin.

Test Method D is recommended for unknown samples, and in instances where fusion of the inorganic portions may be ashm concern. Work Item s – proposed revisions of this 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.

Standard Test Method for Ash Content in Plastics

A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of both. Test Method D is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern.

Six grams of sample is typically used, which represents three crucibles each containing two grams of sample. Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes. TGA Thermogravimetric Analysis is an alternative method to determine filler content with smaller samples sizes.
