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 ...
The FCC has been published since 1966. Before 1960s, although the federal Food and Drug Administration (FDA) had by regulations and informal statements defined in general terms quality requirements for food chemicals generally recognized as safe (), these requirements were not published in the official regulations or designed to be sufficiently specific, therefore their use for general ...
USP 800 (Hazardous Drugs—Handling in Healthcare Settings) is a guideline created by the United States Pharmacopeia Convention (USP), as one of their General Chapters through which the USP "sets quality standards for medicines, dietary supplements and food ingredients".
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 ...

This is a list of chemical elements and their atomic properties, ordered by atomic number (Z). Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
A metallurgical assay is a compositional analysis of an ore, metal, or alloy, usually performed in order to test for purity or quality. Some assay methods are suitable for raw materials; others are more appropriate for finished goods. Raw precious metals are assayed by an assay office.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
