ISO/IEC 17025 and ISO 17034 Base Number (BN) / Total Base Number (TBN) Certified Reference Material (CRM) intended to be used for verification of measuring equipment, method validation, method verification, or other quality control processes used to determine acid number by potentiometric titration, applicable for the test method ASTM D2896, or test methods IP 276, ISO 3771, or other applicable methods.

New and used petroleum products may contain basic constituents that are present as additives. The relative amounts of these materials can be determined by titrating with acids. The neutralization number, which is expressed as base number, is a measure of this amount of basic substance in the oil always under the conditions of the test. The neutralization number is used as a guide in the quality control of lubricating oil formulations. It sometimes is used as a measure of lubricant degradation in service; however, any condemning limits must be empirically established.

base number - n, the quantity of a specified acid, expressed in terms of the equivalent number of milligrams of potassium hydroxide per gram of sample, required to titrate a sample in a specified solvent to a specified endpoint using a specified detection system.
