We supply dual-accredited ISO 17025 and ISO 17034 Total Base Number Reference Standards Paragon. Paragon specifically manufactures these fluids to verify sensitive analytical instruments. Technicians use these instruments to determine base numbers through potentiometric titration. The manufacturer certifies these TBN standards strictly according to ASTM D2896 and IP 276. You can confidently apply them to other internationally equivalent testing methodologies. The TBN value plays a crucial role in the modern lubricants industry. Similar to TAN values, laboratories use TBN to confirm lubricant quality. It strongly supports condition monitoring during active lubricant use. Additives like detergents directly create this measurable TBN. The final value indicates the lubricant’s ability to neutralize harmful operational acids.
