获取电话General Purpose Standards
CANNON certified standards are useful for calibration and verification procedures for all types of viscometers, including glass capillary viscometers, rotational viscometers, falling ball viscometers, cup viscometers, and others. Calibration or verification with a certified viscosity standard helps to ensure the reliability of measurements made with any viscometer.
Quality/Traceability
All CANNON viscosity standards meet the precision specifications of ASTM D 445/446 and ISO 3104/3105, and are traceable to the NIST (National Institute of Standards and Technology). CANNON viscosity standards are manufactured and/or certified in CANNON's ISO 9001 registered and A2LA-accredited laboratory. A2LA has accredited CANNON for technical competence in the field of calibration (certificate number 1262.01). The accreditation includes the determination of kinematic and dynamic viscosity (including that of viscosity standards and customer samples) in accordance with ISO/IEC 17025. All calibrations are based on the master viscometer procedures detailed in ASTM D 2162.
CANNON has been delegated by NIST to provide U.S. national measurement standards and to issue calibration and measurement certificates for certified liquid viscosity reference standards.
Viscosities for all standards sold by CANNON are based on the National Institute of Standards and Technology (NIST) value of 1.0016 mPa·s (centipoise) for water at 20 °C (68 °F).
