Ignition Loss of Resins ASTM D2584

Loss of ignition of Cured Reinforced Resins, in accordance with ASTM D2584

The Ignition Loss of Cured Reinforced Resins is an important test to determine the resin content of a material. This test is performed using the ASTM D2584 test standard, which can also be used to examine the remaining fiber post-burning. The test is particularly useful when only glass reinforcement and organic resin are present, as the ignition loss can then be considered as the resin content.

The ASTM D2584 Test Procedure involves conditioning three 5.0-gram specimens (approximately 2.5 inches by 2.5 inches by thickness) at standard laboratory conditions for a minimum of 40 hours. The specimens are then weighed on an analytical balance to the nearest 0.1 mg. After that, they are placed in pre-dried, pre-weighed crucibles and put into a muffle furnace at 565°C ± 28°C until all carbonaceous material has disappeared. The crucibles are then cooled in a desiccator and reweighed. The ignition loss is then calculated.

The specimen size for this test is 5.0-gram specimens that are approximately 2.5 inches by 2.5 inches by thickness.

The data obtained from this test is crucial to understanding the properties of the material being tested. The ignition loss in weight percent is calculated by the formula VC = (W1 – W2) / W1 * 100, where W1 is the weight of the specimen, and W2 is the weight of the residue.

Overall, the Ignition Loss of Cured Reinforced Resins is an essential test to determine the resin content of a material. By following the ASTM D2584 Test Procedure, valuable data can be obtained, allowing for a better understanding of the material being tested.
