ASTM D – IGNITION LOSS
No further reproductions authorized. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. If only glass reinforcement and organic resin were present, the ignition loss can be considered to be the resin content. D — 11 Assurance Testing Inspection Certification. Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes.
Heat the crucible and specimen in a bunsen? Care must be taken that the ignition does not proceed so rapidly that there will dd2584 a mechanical loss of the noncombustible residue. This service is not available if you are a URL user where you do not log in with an email address. Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes. It can be up to 6 h but is usually much less.
The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. It cannot identify individual percentages in multi-filled materials without additional test procedures being performed. Typically the average of 3 crucibles is reported.
TGA Thermogravimetric Analysis is an alternative method to determine filler content with smaller samples sizes. NOTE 3—Materials that have gross differences in the ratio of resin to reinforcement within an area as small as 2. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
An ash test cannot be used to determine the percent carbon fiber or percent carbon black since carbon burns off during the Ash test. A number in parentheses indicates the year of last reapproval.
Ash Content ASTM D2584, D5630, ISO 3451
The test will identify the total filler content. Specimens obtained from these samples must be dry and the fractured areas removed, leaving square, unfrayed faces, before being weighed and ignited. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
