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.

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. Number of specimens tested by PTLI: 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.

ASTM D – ASH CONTENT (METHOD B)

It cannot identify individual percentages in multi-filled materials without additional test procedures being performed. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. For more efficient ashing, the plastic sample should be in the form of wstm or pellet.

Work Item s – proposed revisions of this standard. Smaller sample weights can be tested but astmm diminishes with smaller sample sizes. Typically the average s5630 3 crucibles is reported. Link to Active This link will always route to the current Active version of the standard.

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. Test Method D is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern. Active view current version of standard. See Section 9 for specific precautionary statements.

Standards can be obtained from appropriate standards authorities. Test Method D is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern. Samples are flamed over a burner prior to being ashed in a muffle furnace.

Ash Content

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 asmt. Note 2 — This test method provides consistent results of filler content for a specific filler in a specific resin.

The test will identify the total filler content. To request a quote for this test d5360 others Click Here. An Ash test is used to determine if a material is filled.

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.

Samples are flamed over a burner prior to being ashed in a muffle furnace. TGA Thermogravimetric Analysis is an alternative method to determine filler r5630 with smaller samples sizes.

Ash levels of 0. The quantitative amounts of each are important variables of the manufacturing process. Note 1 — For more efficient ashing, the plastic sample should be in the form of powder or pellet.

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. Link to Active This link will always route asym the current Active version of the standard. This standard does not purport to address all of the safety concerns, if any, associated with its use. However, this method may not provide the absolute filler content in all cases.
