For information on Metrology, the science of measurement, or calibration, a set of graduations to indicate values or positions, turn to the Internet. This month's Web site review looks at metrology and calibration related sites.
http://ts.nist.gov/ts/htdocs/230/233/calibration. The National Institute for Standards and Technology (NIST) has a Calibration Services home page. This Web site is designed to help manufacturers and operators of precision tools achieve the highest possible levels of measurement quality and productivity. Click User's Guide for a description of calibration services offered by NIST. Some of the measurement areas covered in this site are dimensional, mechanical, thermodynamic, optical radiation, ionizing radiation, electromagnetic, and time and frequency. On this page under the title is a Table of Contents navigation bar. Each category takes visitors to a page with more details and information. Under the Fee Schedule tab, there is a listing of services and fees. For a description of standards-related links, click the Links tab. A definition of traceability is under the Traceability tab, and under the Uncertainty tab, is NIST's policy for reporting measurement uncertainty. Under the Training tab are brief descriptions of the types of training offered, with additional links to listings of upcoming Weights and Measures-related events as well as to general upcoming NIST conferences. The two links at the bottom of the Calibration home page will take visitors to the NIST home page and the NIST technology services home page. The site is easy to navigate.
