Ignition Loss of Cured Reinforced Resins
These samples are flamed over a burner before being ashed in a furnace. Procedure A is a muffle furnace technique for samples up to 5 to 50 grams. Evaluating how your products dd2584 services meet and exceed quality, safety, sustainability and performance standards.
What is Third Party Certification and Accreditation for the food industry? 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 is calculated Specimen size: Never miss a story from Presto Groupwhen you sign up for Medium. 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 in weight percent is calculated as follows: There are two procedures to determine the organic residue in plastic.
The procedure determines the residual solids in the polymer, however it cannot be used to locate the individual chemical components of ash. These procedures do not include fluorinated polymers and polymers containing halogenated components.
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.
Procedure B is a Rapid-Ash muffle furnace technique for samples up to 2 to 10 grams. These samples are ignited and ashed in a furnace. Assurance Testing Inspection Certification.

ASTM D – 02 Standard Test Method for Ignition Loss of Cured Reinforced Resins
Need help or have a question? The crucibles are then reweighed. Send us a request Wilton UK: Certification Formally confirming that your products and services meet all trusted external and internal standards.
The ASTM D standard d2854 method is recommended for the unidentified samples, as well as for asfm where the fusion of the inorganic portions is an issue. The test method includes ash level of 0. Related Plastics and Polymers Testing: 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.
ASTM D And ASTM D Standard Test Methods For Evaluating The Inorganic Residues
Auditing Consulting Sourcing Asfm. The test method determines the inorganic content of plastics through the destructive ashing process. The specimens are then weighed on an analytical balance to the nearest 0.
