  2. Certified reference materials - Wikipedia

    en.wikipedia.org/wiki/Certified_reference_materials

    In addition, commercial producers adhering to criteria and protocols defined by NIST may use the trademark [13] "NIST traceable reference material" to designate certified reference materials with a well-defined traceability linkage to existing NIST standards for chemical measurements. [14] [15]

    en.wikipedia.org/wiki/Kibble_balance

    For instance, in the basement of the NIST's Gaithersburg facility in 2009, when measuring the gravity acting upon Pt‑10Ir test masses (which are denser, smaller, and have a slightly lower center of gravity inside the Kibble balance than stainless steel masses), the measured value was typically within 8 ppb of 9.801 016 44 m/s 2.

    This NTEP Certificate of Conformance indicates that the device manufacturer has demonstrated the ability to meet applicable requirements for commercial weighing and measuring equipment in the United States as specified in Handbook 44: Specifications and Tolerances and Other Technical Requirements. NTEP certification is required in most states ...

    en.wikipedia.org/wiki/National_Institute_of...

    NIST had an operating budget for fiscal year 2007 (October 1, 2006 – September 30, 2007) of about $843.3 million. NIST's 2009 budget was $992 million, and it also received $610 million as part of the American Recovery and Reinvestment Act. [18] NIST employs about 2,900 scientists, engineers, technicians, and support and administrative personnel.

  6. Traceability - Wikipedia

    en.wikipedia.org/wiki/Traceability

    Within a product's supply chain, traceability may be both a regulatory and an ethical or environmental issue. [3] Traceability is increasingly becoming a core criterion for sustainability efforts related to supply chains wherein knowing the producer, workers and other links stands as a necessary factor that underlies credible claims of social, economic, or environmental impacts. [4]

  7. Check weigher - Wikipedia

    en.wikipedia.org/wiki/Check_weigher

    The traditional "minimum weight" system where weights below a specified weight are rejected. Normally the minimum weight is the weight that is printed on the pack or a weight level that exceeds that to allow for weight losses after production such as evaporation of commodities that have a moisture content.

  8. Standard temperature and pressure - Wikipedia

    en.wikipedia.org/wiki/Standard_temperature_and...

    However, a common temperature and pressure in use by NIST for thermodynamic experiments is 298.15 K (25 °C, 77 °F) and 1 bar (14.5038 psi, 100 kPa). [4] [5] NIST also uses 15 °C (288.15 K, 59 °F) for the temperature compensation of refined petroleum products, despite noting that these two values are not exactly consistent with each other.

  9. International Bureau of Weights and Measures - Wikipedia

    en.wikipedia.org/wiki/International_Bureau_of...

    The International Bureau of Weights and Measures (French: Bureau International des Poids et Mesures, BIPM) is an intergovernmental organisation, through which its 64 member-states act on measurement standards in areas including chemistry, ionising radiation, physical metrology, as well as the International System of Units (SI) and Coordinated Universal Time (UTC).
