ACS grade is the highest level of purity, and meets the standards set by the American Chemical Society (ACS). The official descriptions of the ACS levels of purity is documented in the Reagent Chemicals publication, issued by the ACS. [3] [4] It is suitable for food and laboratory uses. Reagent grade is almost as stringent as the ACS grade.
21 C.F.R. 211.110 (a)(6) states that bioburden in-process testing must be conducted pursuant to written procedures during the manufacturing process of drug products. [3] The United States Pharmacopeia (USP) outlines several tests that can be done to quantitatively determine the bioburden of non-sterile drug products. [4]
Products that meet the requirements of the program can display the USP Verified Dietary Supplement Mark on their labels.

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".
The USP Controlled Room Temperature is a series of United States Pharmacopeia guidelines for the storage of pharmaceuticals; [1] the relevant omnibus standard is USP 797. [2] [3] Although 100% compliance remains challenging for any given facility, [4] the larger protocol may be regarded as constituting a form of clean room [5] which is included in a suite of best practices.
Several grades of this material are available depending on the level of ethoxylation performed, with repeat units (n) of polyethylene glycol varying between 2 and 20. Commercially it can be known as Cetomacrogol 1000, Brij 58 (when n =20), Brij 56 (when n =10), and other trade names.
The precious metal purity and content of these coins is guaranteed by the respective mint or government, and, therefore, the assay of the raw materials and finished coins is an important quality control. In the UK, the Trial of the Pyx is a ceremonial procedure for ensuring that newly minted coins conform to required standards.
