In its own activities as a scientific institution, NIST uses many different materials, products, types of equipment, and services. This use does not imply that NIST has given them a preferential position or a formal endorsement. Therefore, NIST discourages references, either in advertising or in the scientific literature, which identify it as a user of any proprietary product, material, or service. Occasionally, effective communication of results by NIST to the scientific community requires that a proprietary instrument, product, or material be identified in an NIST publication. Reference in an NIST publication, report, or other document to a proprietary item does not constitute endorsement or approval of that item and such reference should not be used in any way apart from the context of the NIST publication, report, or document without the advance express written consent of NIST.
