See Section 9 for specific precautionary statements. Ash levels of 0. Note 2 — This test method provides consistent results of filler content for a specific filler in a specific resin.

Typically the average of 3 crucibles is reported. Link to Active This link r5630 always route to the current Active version of the standard. Ash levels of 0.

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, r5630 plastic sample should be in the form of powder or pellet. Historical Version s – view previous versions of standard.

Samples are flamed over a burner prior to being ashed in a muffle furnace. An ash test cannot be used to determine the percent carbon fiber or percent carbon black since carbon burns off during the Ash test. Six grams of sample is typically used, which represents three crucibles each containing two grams of sample. Samples are ignited and ashed in a muffle furnace.

An Ash test is used to determine if a material is filled. The quantitative amounts of each are important variables of the manufacturing process. To request a quote for this test or others Click Here. A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of both. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

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. For more efficient ashing, the plastic sample should be in the form of powder or pellet. However, this method may not provide the absolute filler content in all cases.

Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes. 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.

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. It ast, identify individual percentages in multi-filled materials without additional test procedures being performed.

Test Method D is recommended for unknown samples, and in instances where x5630 of the inorganic portions may be of concern. TGA Thermogravimetric Analysis is an alternative method to determine filler content with smaller samples sizes.
