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. Typically the average of 3 crucibles is reported.

Note 1 — For more efficient ashing, the plastic sample should be in the form of powder or pellet.

Ash levels of 0.

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. An ash test cannot be used to determine the percent carbon fiber or percent carbon black since carbon burns off during the Ash test. Samples are ignited and ashed in a muffle furnace.

Samples are flamed over a burner prior ast being ashed in a muffle furnace. TGA Thermogravimetric Analysis is an alternative method to determine zstm content with smaller samples sizes. See Section 9 for specific precautionary statements.

Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes. An Ash test is used to determine if a material is filled. 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. The test will identify the total filler content. Asgm to Active This link will always route to the current Active version of the standard.

Samples are flamed over a burner prior to being 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.

A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of both.

However, this method may not provide the absolute filler content in all cases.

Test Method D is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern. Note 2 — This test method provides consistent results of filler content for a specific filler in a specific resin.

Work Item s – proposed revisions of this standard. The quantitative amounts of each are important variables of the manufacturing process. Ash levels of 0. It cannot identify individual percentages in multi-filled materials without additional test procedures being performed.
