Procedure B is a Rapid-Ash muffle furnace technique for samples up to 2 to 10 grams. The ASTM D standard test method is recommended for the unidentified samples, as well as for samples where the fusion of the inorganic portions is an issue.
The specimens are then weighed on an analytical balance to the nearest 0. The test method determines the inorganic content of plastics through the destructive ashing process. The procedure determines the residual solids in the polymer, however it cannot be used to locate the individual chemical components of ash.
The ASTM test method is recommended for evaluating the inorganic residues from plastics ash, which is important to study for the manufacturing process.

The ignition loss is calculated Specimen size: Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The test method determines the ignition loss of a cured reinforced resin sample and examines the fiber architecture of pultruded structural shapes. The test methods do not measure the resin content of a sample that contains the reinforcing materials losing weight under test conditions or that contains resins or fillers that do not decompose to explosive materials released by ignition.
Procedure A is a muffle furnace technique for samples up to 5 to 50 grams. Send us a request Wilton UK: Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
If organic resin reinforcement is only glass fabric or filament that is entirely decomposed to volatile materials under the test conditions and the small amount of volatiles water, residual solvent are ignored, the resin content of the sample is considered as the ignition loss.
Ignition Loss of Cured Reinforced Resins
If only glass reinforcement and organic resin were present, the ignition loss can be considered resin content. Formally confirming that your products and services meet all trusted external and internal standards. These samples are flamed over a burner before being ashed in a furnace. The ignition loss in weight percent is calculated as follows: The crucibles are then reweighed.
