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.

Test Method D is recommended for unknown samples, and in instances d560 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.

ASTM D5630

Work Item s – proposed revisions of this standard. Link to Active This link will always route to the current Active version of the standard. Standards can be obtained from appropriate standards authorities. An Ash test is used to determine if a material is filled. D563 are flamed over a burner prior to being ashed in a muffle furnace. The test will identify the total filler content.

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

Link to Active This link will always route to the current Active version 5d630 the standard. TGA Thermogravimetric Analysis is an alternative method to determine filler content with smaller samples sizes. However, this method may not provide the absolute filler content in all cases.

The quantitative amounts of each are important variables of the manufacturing process. Samples are ignited and ashed in a muffle furnace. This standard does not purport to address all of the safety concerns, if any, associated with its use.

Note 2 — This test method provides consistent results of filler content for a specific filler in a specific resin. Typically the average aastm 3 crucibles is reported. Samples are ignited and ashed in a muffle furnace. 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.

Note 1 — For more efficient ashing, the plastic sample should be in the form of powder or pellet. Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes. Number of specimens tested by PTLI: See Section 9 for specific precautionary statements. To request a quote for this test or others Click Here. Active view current version of standard. Six grams of sample is typically used, which represents three crucibles each containing two grams of sample.

Identification of Filler If the supplied material has mineral filler an FTIR analysis of the ash residue can help to further identify the type of mineral.

Ash levels of 0. For more efficient ashing, the plastic sample should be in the form of powder or pellet.

See Section 9 for asmt precautionary statements. A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of both.
