Send us a request Need help or have a question? The crucibles are then cooled in a desiccator. Related Asym and Polymers Testing: Send us a request Wilton UK: Procedure B is a Rapid-Ash muffle furnace technique for samples up to 2 to 10 grams. If only glass reinforcement and organic resin were present, the ignition loss can be considered resin content.
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.
The test method determines the ignition loss of a cured reinforced resin sample and examines the fiber architecture of pultruded structural shapes. Certification Formally confirming that your products and services meet all trusted external and internal standards. Need help or have a question? The test method includes ash level of 0.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. These procedures do not include fluorinated polymers and polymers containing halogenated components.
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 test method determines the inorganic content of plastics through the destructive ashing process.
The ASTM test method is recommended for evaluating the inorganic residues from plastics ash, which is important to study for the manufacturing process. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
Formally confirming that your products and services meet all trusted external and internal standards. The ignition loss in weight percent is calculated as follows: There are two procedures to determine the organic residue in plastic.

Ignition Loss of Cured Reinforced Resins
The ignition loss is calculated Specimen size: These samples are flamed over a burner before satm ashed in a furnace. Become a member Sign in Get started.

Ignition Loss of Cured Reinforced Resins
Validating the specifications, value and safety asstm your raw materials, products and assets. 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 d22584 considered as the ignition loss. The procedure determines the residual solids in the polymer, however it cannot be used to locate the individual chemical components of ash.
