  • In this e-Learning module, the AFS 5100-12-S: Loss on Ignition (LOI) test will be performed. This module also incorporates the AFS 5101-12-S: Magnetic Material, Removal, and Determination sand test as part of the LOI test. Topics that will be covered: purpose of the tests, basic variables that factor into the tests, and performing the tests in a virtual environment. By the end of this module, you will be able to measure the weight change of a sample, consisting of weight losses and weight gains when a sample is fired at 1,800°F [982°C]. This includes weight loss due to volatilization of organics, weight loss due to removal of chemically bound water, weight loss due to dissociation or inorganic compounds with one or more components given off as a gas, and weight gain due to oxidation reactions (specifically chromite, olivine, and magnetite). You will also be able to remove magnetic materials in a sand sample and determine magnetic content. (0.1 CEU)
