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.

Test Method D is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern. Samples are ignited and ashed in a muffle furnace.

See Section 9 for specific precautionary statements. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Work Item s – proposed revisions of this 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.

An Ash test is used to determine if a material is filled.

Standard Test Method for Ash Content in Plastics

For more efficient ashing, the plastic sample should be in the form of powder or pellet. Six grams of sample is typically used, which represents three crucibles each containing two grams of sample. Standards can be obtained from appropriate standards authorities. TGA Thermogravimetric Analysis is an alternative method to determine filler content with smaller samples sizes. asttm

Samples are flamed over a burner prior to being ashed in a muffle furnace. 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.

It cannot identify individual percentages in multi-filled materials without additional test procedures being v5630.

Ash Content

The test will identify the total filler content. Ash levels of 0. 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. Qstm quantitative amounts of each are important variables of the manufacturing process.
