ASTM D – 02 Standard Test Method for Ignition Loss of Cured Reinforced Resins
The ASTM test method is recommended for evaluating the inorganic residues from plastics ash, which is important to study for the manufacturing process. Procedure B is a Rapid-Ash muffle furnace technique for samples up to 2 to 10 grams. The test method determines the inorganic content of plastics through the destructive ashing process.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains adtm business processes. Procedure A is a muffle furnace technique for samples up to 5 to 50 grams. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Never miss a story from Presto Groupwhen you aetm up for Medium.
ASTM D – 18 Standard Test Method for Ignition Loss of Cured Reinforced Resins
Formally confirming that your products and services meet all trusted external and internal standards. Become a member Sign in Get started. What is Third Party Certification and Accreditation for the food industry? 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.
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. Validating the specifications, value and safety of your raw materials, products and assets. These samples are flamed over a burner before being ashed in a furnace.
Send us a request Wilton UK: The crucibles are then cooled in a desiccator. Assurance Testing Inspection Certification. The procedure determines the residual asfm in the polymer, however it cannot be used to locate the individual chemical components of ash.
Ignition Loss of Cured Reinforced Resins
r2584 Auditing Consulting Sourcing Training. The crucibles are then reweighed. The ignition loss is calculated Specimen size: The ignition loss in weight percent is calculated as follows: The test method determines the ignition loss of a cured reinforced resin sample and examines the fiber architecture of pultruded structural shapes.
Blocked Unblock Follow Get updates. Whether your business is local or global, we can ensure aastm products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
Need help or have a question? If only glass reinforcement and organic resin were present, the ignition loss can be considered resin content. There are two procedures to determine the organic residue in plastic. These samples are ignited and ashed in a furnace.
