The dropping point is the temperature at which a substance passes from a semi-solid to a liquid state.
The pour point of a liquid is the lowest temperature at which it becomes semi solid. This is where the liquid loses its flow characteristics.
Acid value (or neutralization number or acid number or acidity) is the mass of potassium hydroxide (KOH) in milligrams that is required to neutralize one gram of chemical substance. The acid number is a measure of the number of carboxylic acid groups in a chemical compound, such as a fatty acid.
Saponification value or saponification number (SV or SN) represents the number of milligrams of potassium hydroxide (KOH) required to saponify one gram of fat under the conditions specified.
The hydroxyl value of a substance is the amount, in milligrams, of potassium hydroxide required to neutralize any acid when combined by acylation in 1 g of the substance under examination.
The iodine value (or iodine adsorption value or iodine number or iodine index, commonly abbreviated as IV) is the mass of iodine in grams that is consumed by 100 grams of a chemical substance. Iodine value is used to determine the amount of unsaturation in fats, oils and waxes.
