ASTM F has publi A number in parentheses indicates the year of last reapproval. This standard has been approved for use by agencies of the Department of Defense. This ignition loss can be considered to be the resin content within the zstm of 4.

Adequate safeguards for personnel and property shall be employed in conducting these tests. It is the responsibility of whoever d25584 this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D – 18 Standard Test Method for Ignition Loss of Cured Reinforced Resins

This test method can also be used to examine the? NOTE 2—It is often convenient to use samples obtained zstm specimens that have been tested for mechanical properties such as?

Specimens obtained from these samples must be dry and the fractured areas removed, leaving square, unfrayed faces, before being weighed and ignited. Summary of Test Method 3. Current edition approved Oct.

Originally approved in Last previous edition approved in as D – NOTE 3—Materials that have gross differences in the ratio of resin to reinforcement within an asgm as small as 2. If larger specimens are utilized, it will be necessary to cut into approximately 2. No further reproductions authorized.


D — 11 7. The conditioning is not required if the test is only d5284 to examine the? Cool to room temperature in a desiccator and weigh to the nearest 1. The desiccator is not required if the test is performed only to examine the? Heat the crucible and specimen in a bunsen? Maintain such a temperature that the specimen burns at a uniform and moderate rate until only ash and carbon remain when the burning ceases.

NOTE 4—It is not absolutely necessary to ignite the specimen in a bunsen? Care must be taken that the ignition does not proceed so rapidly that there will be a mechanical loss of the noncombustible residue. If only glass reinforcement and organic resin were present, the ignition loss can be considered to be the resin content.

ASTM D2584 – 11

Precision and Bias For each material, all the samples were prepared at one source, but the individual specimens were prepared at the laboratories which tested them. Each test result was the average of three individual determinations. Each laboratory obtained two test results for each material. The data in Table 1 should not be applied to acceptance or rejection of materials, as these data apply only to the materials tested in the round robin and are unlikely to be rigorously representative of other lots, formulations, conditions, materials, or laboratories.

Users of this test method should apply the principles outlined in Practice E to generate data speci? The principles of Cool the crucible to room temperature in a desiccator and weight to the nearest 1. NOTE 5—The time for the carbonaceous residue to disappear is dependent largely on the specimen geometry. It can be up to 6 h but is usually much less.


Ash Content
