Volumetric instruments according to USP error limits:

• Companies producing pharmaceutical products for the US market are supervised by US authorities, e.g. the FDA (Food and Drug Administration), and have to meet the requirements of the USP (United States Pharmacopeia).
• The current USP prescribes in section 31 the use of volumetric instruments with accuracy in accordance to class A of the ASTM standards and list those for volumetric flasks, transfer pipettes and burettes in tables.
• BRAND volumetric instruments are manufactured according to the current DIN EN ISO standards. As the construction specifications are differently defined in the DIN EN ISO and ASTM standards, the error limits differ as well. With included USP certificates BRAND confirms for the delivered USP volumetric instruments that the class A error limits according to the USP or, rather, ASTM standards are met.

Every glass volumetric measuring instrument is individually calibrated:

• Computer-controlled systems ensure maximum precision in a fully automated production line. The final step of this Statistical Process Control is random sampling of finished product according to DIN ISO 3951. The quality management system applied at BRAND, which is certified according to DIN EN ISO 9001, is a combination of process monitoring and random checks with an accepted quality level (AQL) of approximately 0.4.
• The batch certificate confirms that ASTM class A error limits required by USP are met. The certificate records the mean value, the standard deviation of the batch and the date of issue (batch number: year of manufacture/batch).
