A short overview
Standards for volumetric measuring devices
1. DIN (Deutsches Institut für Normung), the German Institute for Standardization
DIN standards are German standards compiled by working committees within DIN to maintain the general standard of technology. Adherence to the DIN standard is a component part of the calibration certificate issued pursuant to the German Calibration Regulation (Eichordnung).
2. ISO (International Organization for Standardization)
ISO standards are international standards compiled by the International Organization for Standardization. These international standards are adopted as German standards.
3. ASTM (American Society for Testing and Materials)
ASTM standards are international standards compiled for the USA.
4. USP (United States Pharmacopoeia)
USP standards are American standards specially compiled for the pharmaceutical sector. Tolerances for volumetric measuring devices are defined in these standards.
