ASTM D5630 PDF

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.

TGA Thermogravimetric Analysis is an alternative method to determine filler content with smaller samples sizes. For more efficient ashing, the plastic sample should be in the form of powder or pellet. An ash test cannot be used to determine the percent carbon fiber or percent carbon black since carbon burns off during the Ash test. Note 1 — For more efficient ashing, the plastic sample should be in the form of powder or pellet.

Standards can be obtained from appropriate standards x5630. Samples are flamed over a burner prior to being ashed in a muffle furnace.

Ash Content

The quantitative amounts of each are important variables of the manufacturing process. Link to Active This link will always route to the current Active version of the standard. Six grams of sample is typically used, which represents three crucibles each containing two grams of sample.

Number of specimens tested by PTLI: Note 2 — This test method provides consistent results of filler content for a specific filler in a specific resin. Ash levels of 0.

The test will identify the total filler content. Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes. A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of both.

Samples are ignited and ashed in a muffle furnace. However, this method may not provide the absolute filler content in all cases. Samples are ignited and ashed in a muffle furnace.

ASTM D – ASH CONTENT (METHOD B)

Test Method D is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern. It cannot identify individual percentages in multi-filled materials without additional test procedures being performed.

Work Item s – proposed revisions of this standard. 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. This standard does not purport to address all of the safety concerns, if any, associated with its use. Samples are flamed over a burner prior to being ashed in a muffle furnace.

Typically the average of 3 crucibles is reported. An Ash test is used to determine if a material is filled. 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.
