VWR®, Total Base Number (TBN) standards
标准品 Petroleum Industry Standards
Total Base Number (TBN) standards are specifically manufactured for the verification of analytical instruments used to determine base number by potentiometric titration. Each standard is certified in strict accordance with international test method protocols, ASTM D2896 / IP 276.
- Typically used in, but not limited to, the analysis of used oils and lubricants
- Base Number (BN) tested and certified in accordance with ASTM D2896 / IP 276
- Fully traceable to international standards and low levels of uncertainty achieves maximum accuracy of data
- Supplied in tamper-evident glass packaging, providing assurance of sample integrity
Certifications: Manufacture and certification is carried out in strict accordance with dual-UKAS accreditations to ISO 17025 and ISO 17034. This dual-accreditation ensures the highest level of accreditation guarantee, and provides the most credible certified data available worldwide.
Caution: The concentration value given in the ordering table below is the nominal concentration for the TBN value - actual batch values are given in the certification documents supplied with the product and also on the label.
