  2. Food Chemicals Codex - Wikipedia

    en.wikipedia.org/wiki/Food_Chemicals_Codex

    Monographs may also detail USP Reference Standards and/or other materials needed for test performance. The FCC's appendices contain step-by-step guidance for general physical and chemical tests, and apparatus use, as well as generally useful information, such as food ingredient good manufacturing practices .

  3. Chemical purity - Wikipedia

    en.wikipedia.org/wiki/Chemical_purity

    USP grade meets the purity levels set by the United States Pharmacopeia (USP). USP grade is equivalent to the ACS grade for many drugs. NF grade is a purity grade set by the National Formulary (NF). NF grade is equivalent to the ACS grade for many drugs. British Pharmacopoeia: Meets or exceeds requirements set by the British Pharmacopoeia (BP ...

  4. Certified reference materials - Wikipedia

    en.wikipedia.org/wiki/Certified_reference_materials

    A certified reference material is a particular form of measurement standard. Reference materials are particularly important for analytical chemistry and clinical analysis. [2] Since most analytical instrumentation is comparative, it requires a sample of known composition (reference material) for accurate calibration.

    Products that meet the requirements of the program can display the USP Verified Dietary Supplement Mark on their labels. [5] This is different from seeing the letters "USP" alone on a dietary supplement label, which means that the manufacturer is claiming to adhere to USP standards. USP does not test such products as it does with USP Verified ...

  6. Drug reference standard - Wikipedia

    en.wikipedia.org/wiki/Drug_reference_standard

    Pharmacopeial reference standards are available from various pharmacopoeias such as United States Pharmacopeia and the European Pharmacopoeia. Where pharmacopoeial tests or assays call for the use of a pharmacopoeial reference standard, only those results obtained using the specified pharmacopoeial reference standard are conclusive. [citation ...

  7. Reference materials for stable isotope analysis - Wikipedia

    en.wikipedia.org/wiki/Reference_materials_for...

    The δ values and absolute isotope ratios of common reference materials are summarized in Table 1 and described in more detail below. Alternative values for the absolute isotopic ratios of reference materials, differing only modestly from those in Table 1, are presented in Table 2.5 of Sharp (2007) [1] (a text freely available online), as well as Table 1 of the 1993 IAEA report on isotopic ...

  8. Bioburden - Wikipedia

    en.wikipedia.org/wiki/Bioburden

    The United States Pharmacopeia (USP) outlines several tests that can be done to quantitatively determine the bioburden of non-sterile drug products. [4] It is important when conducting these tests to ensure that the testing method does not either introduce bacteria into the test sample or kill bacteria in the test sample. [4]

  9. ISO 10993 - Wikipedia

    en.wikipedia.org/wiki/ISO_10993

    The ISO 10993 set entails a series of standards for evaluating the biocompatibility of medical devices to manage biological risk. These documents were preceded by the Tripartite agreement and is a part of the international harmonisation of the safe use evaluation of medical devices. [1]
