Glass Beads for Sieve Calibration -Testing Sieve Standards- NIST traceability and are optimal for performance testing and establishing effective openings of sieves from No. 6 to No. 635 (3.35mm to 20µm). While sieve standards do not take the place of Verification, periodic checks serve as an indicator of when to replace sieves, and these calibrations can be performed in minutes with no need to ship the sieves back or take them out of service. Highly spherical beads made from 2.45 specific gravity soda-lime glass are certified for size using precision electroformed sieves with checks using microscopy and image analysis. After processing on a sieve, the average aperture size is quickly read from the provided calibration graph. Each Sieve Standard comes as five single-use vials of glass beads for use with a single sieve size. A single vial is used for 8in or 200mm sieves, while two to five vials are used for sieves up to 18in or 450mm in diameter. Sieve Standard has been selected by the Community Bureau of Reference (BCR) to produce standards for the European Community. This Sieve Standards are traceable to NIST, NPL and BCR. Single-shot glass microsphere standards Supplied in sets of 5 single shot bottles, each shot is suitable for one calibration test, thereby avoiding operator error. These provide a quick and economical method of calibrating sieves. The references, nearly all NIST traceable range in size from 0.1µm to 5.0mm and are available as single sizes or broad distribution standards.

Certified reference materials for Testing and Research We offers manufactured high quality certified reference standards and certified components for test kits, we distribute certified reference materials from internationally recognized CRM producers such as Joint Research Centre Institute for Reference Materials and Measurements (IRMM) JRC-IRMM, British Standards Institution - BSI and Whitehouse Scientific. BS - BSI Group The BSI catalog contains over 50,000 standards in PDF format, of which 31,000 are current. It includes standards of UK origin, European standards from CEN/CENELEC and international standards from ISO and IEC which have been adopted in the UK. BSI standards cover building and civil engineering, materials and chemicals, electrotechnology, consumer products and services, healthcare, management systems and information technology ASTM International ASTM International, formerly known as the American Society for Testing and Materials (ASTM), is a globally recognized leader in the development and delivery of international voluntary consensus standards. Today, some 13,000 ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. International Organization for Standardization ISO is a global federation of national standards bodies from approximately 100 countries. ISO standards are accepted worldwide as the method by which manufacturers and service providers can achieve maximum convenience and efficiency in the exchange of goods and services. NIST NIST is the federal technology agency that works with the industry to develop and apply technology, measurements and standards. NIST supplies industry, academia, government, and other users with over 1200 reference materials of the highest quality and metrological value. Glass Beads for Sieve Calibration -Testing Sieve Standards- NIST traceability and are optimal for performance testing and establishing effective openings of sieves from No. 6 to No. 635 (3.35mm to 20µm). While sieve standards do not take the place of Verification, periodic checks serve as an indicator of when to replace sieves, and these calibrations can be performed in minutes with no need to ship the sieves back or take them out of service. Highly spherical beads made from 2.45 specific gravity soda-lime glass are certified for size using precision electroformed sieves with checks using microscopy and image analysis. After processing on a sieve, the average aperture size is quickly read from the provided calibration graph. Each Sieve Standard comes as five single-use vials of glass beads for use with a single sieve size. A single vial is used for 8in or 200mm sieves, while two to five vials are used for sieves up to 18in or 450mm in diameter. Sieve Standard has been selected by the Community Bureau of Reference (BCR) to produce standards for the European Community. This Sieve Standards are traceable to NIST, NPL and BCR. Single-shot glass microsphere standards Supplied in sets of 5 single shot bottles, each shot is suitable for one calibration test, thereby avoiding operator error. These provide a quick and economical method of calibrating sieves. The references, nearly all NIST traceable range in size from 0.1µm to 5.0mm and are available as single sizes or broad distribution standards. Sieve calibration using glass microspheres Recommended number of bottles per sieve 200mm Diameter Sieve 1 bottle 300mm Diameter Sieve 2 bottles 450mm Diameter Sieve 5 bottles *For a 1000mm sieve & 2000mm please contact us These Sieve Calibration Beads are manufactured from soda-lime glass and certified using NIST & NPL traceable electroformed sieves. They are accurate to 1 micron for the smaller aperture sieves and are supplied with a certificate of analysis. For ordering/more information, please contact us.
