ASTM D is used to determine ignition loss of cured reinforced resins and can be used to examine the remaining fiber post burning. If only glass. ASTM A/AM Steel, Sheet and Strip, Heavy-Thickness Coils, Hot- Rolled, Carbon, Commercial, Drawing, Structural, High-Strength Low-Alloy. This standard is issued under the fixed designation D ; the number 1 This test method is under the jurisdiction of ASTM Committee D on Plastics.

This ensures that you are always up-to-date and saves you both time and money.
Certification Formally confirming that your products and services meet all trusted external and internal standards. Standards can be obtained from appropriate standard authorities.
Six grams of sample is astj used, which represents three crucibles each containing two grams of sample. This test method can also be used to examine the? If you need to be able to add standards to the monitoring service, you must register as a user with your own username and password. Number of specimens tested by PTLI: Cool the crucible to room temperature in a desiccator and weight to the nearest 1.
D — 11 If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of both. TGA Thermogravimetric Analysis is an alternative method to determine filler content with smaller samples sizes.
Start Webshop Product catalog Product presentation. Webprint Printed and bound. D2548 comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes.
ASTM D – 11 – Standard Test Method for Ignition Loss of Cured Reinforced Resins
An ash test cannot be used to determine the percent carbon fiber or percent carbon black since carbon burns off during the Ash test. This standard has been approved for use by agencies of the Department of Defense. Users xstm this test method should apply the principles outlined in Practice E to generate data speci? Validating the specifications, value and safety of your raw materials, products and assets.
Current edition approved Oct.
ASTM D2584 – 11
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. NOTE 4—It is not absolutely necessary to ignite the specimen in a bunsen? A number in parentheses indicates the year of last reapproval.
Specimens obtained from these samples must be dry and the fractured areas removed, leaving square, unfrayed faces, before being weighed and ignited. A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of both. The data in Table 1 should not be applied to acceptance or rejection of d2854, as these data apply only to the materials tested in the round robin and ast, unlikely to be rigorously representative of other lots, formulations, conditions, materials, or laboratories.
Originally approved in It cannot identify individual percentages in multi-filled materials without additional test procedures being performed.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The moment new satm of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.
Typically the average of 3 crucibles is reported. You need to log in before adding standards to the monitoring service. Maintain such a temperature that the specimen burns at a uniform and moderate rate until only ash and carbon remain when the burning ceases. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Care must be taken that the ignition does not proceed so rapidly that there will be a mechanical loss of the noncombustible residue.
Last previous edition approved in as D – It can be up to 6 awtm but is usually much less.
Six grams of sample is typically used, which represents three crucibles each containing two grams of sample. The test will identify the total filler content. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
