This test method is used to determine the temperature of a substance using a certified thermometer.
This test method determines the color of oils and other transparent liquids by comparing samples to calibrated Lovibond® or Gardner liquid standards, providing a standardized visual evaluation of red/yellow (RYBN) tint and overall Gardner color to ensure consistent color grading across batches.
This test method determines the concentration of glycerin with a calculation involving the specific gravity and relative density of the glycerin sample.
This test method is a gravimetric and titrimetric procedure used to quantify the calcium carbonate (CaCO₃) content in samples such as limestone, feed supplements, and pharmaceuticals. The method measures the amount of carbonate by reacting the sample with acid and quantifying the calcium present, providing an estimate of the CaCO₃ concentration.
