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.

Typically the average of 3 crucibles is reported.

ASTM D – 13 Standard Test Method for Ash Content in Plastics

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 xstm the absolute filler content in all cases.

Samples are flamed over a burner prior to being ashed in a muffle furnace. This standard does not purport to address all of the safety concerns, if any, associated with its use. Note 1 — For more efficient ashing, the plastic sample should be in the form of powder or pellet. Link to Active This link will always route to the current Active version of the standard.

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

ASTM D – ASH CONTENT (METHOD B)

It cannot identify individual percentages in multi-filled materials without additional test procedures being performed. An Ash test is used to determine if a material is filled. Active view current version of standard Translated Standard: See Section 9 for specific precautionary statements. Samples are ignited and ashed in a muffle furnace.

Ash levels of 0. Samples are ignited and ashed in a muffle furnace. Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes. 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.

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. The quantitative amounts of each are important variables of the manufacturing process. Number of specimens tested by PTLI: Work Item s – proposed revisions of this standard. The test will identify the total filler content. Six grams of sample is typically used, which represents three crucibles each containing two grams of qstm.

Due to copyright restrictions, we are not able to provide copies of standards. See Section 9 for specific precautionary statements. Ash levels of 0. Test Method D is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the aatm of regulatory limitations prior to use. 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. An ash test cannot be used to determine the percent carbon fiber or percent carbon black since carbon burns off during the Ash test.

Work Item s – proposed revisions of this standard. A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of x5630.
