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.

Active view current version of standard Translated Standard: Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes. Test Method D is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern. Standards can be obtained from appropriate standards authorities. An Ash test is used to determine if a material is filled. Test Method Asstm is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern.

TGA Thermogravimetric Analysis is an alternative method to determine filler content with smaller samples sizes.

Work Item s – proposed revisions of this standard. It cannot identify individual percentages in multi-filled materials without additional test procedures being performed. See Section 9 for specific precautionary statements. The quantitative amounts of each are important variables of the manufacturing process.

Ash Content

The test will identify the total filler content. Ash levels of 0.

However, this method may not provide the absolute filler content in all cases. Number of specimens tested by PTLI: 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.

An ash test cannot be used wstm determine the percent carbon fiber or percent carbon black since sstm burns off during the Ash test. Due to copyright restrictions, we are not able to provide copies of standards.

A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination asm both. To request a quote for this test or others Click Here.

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

Note 1 — For more efficient ashing, the plastic sample should be in the form of powder or pellet. Ash levels of 0.

Six grams of sample is typically used, which represents three crucibles each containing two grams of sample. Work Item s – proposed revisions of this standard. Samples are ignited and ashed in a muffle furnace. This standard does not purport to address all of the safety concerns, if any, associated with its use.
