Although rectal temperature (RCT) is the preferred and recommended method of the National Athletic Trainers' Association (NATA) for assessing core body temperature, 2 athletic trainers use a variety of body sites and devices to measure temperature. 3 Common alternatives include oral, aural (tympanic), temporal, and axillary temperature. This provides traceability of measurement to recognized national standards and to units of measurement realized at the “National Physical Laboratory” (NPL) or other recognized national standards laboratories like “Physikalisch-Technische Bundesanstalt” (PTB) or “National Institute of Standards and Technology” (NIST).

A detailed guide to many aspects of humidity measurement. It covers humidity concepts and definitions, methods of measurement, instrument performance and calibration, and good measurement practices for humidity. Worked examples illustrate the effects of temperature and pressure changes on humidity. Includes tables, charts and formulae and extensive bibliography. ASTM's temperature measurement standards provide the material and property specifications, as well as guides for the testing, calibration, and use of laboratory, industrial, and clinical instruments used in the determination of thermal variables, particularly temperature.

Eventbrite - National Physical Laboratory presents Temperature Measurement & Humidity Measurement Calibration Course - Monday, 10 May | Friday, 14 May at National Physical Laboratory, Teddington, England.

Find event and ticket information. Add tags for "Temperature measurement at the National Physical Laboratory; collected papers ,". Be the first. Volume 1 of the Handbook of Temperature Measurement, prepared by the CSIRO National Measurement Laboratory, Australia, details the principles and techniques involved in the measurement of humidity, in cryogenic and radiation thermometry and a variety of unconventional methods of temperature measurement.

Other topics considered are thermal conductivity and the traceability of measurement. However, the emphasis will be on practical aspects of temperature measurement, calibration and traceability, with a lot of time being spent in laboratories.

The optional third day will provide opportunities for more in-depth training and ‘hands-on’ experience of some of the calibration techniques used in the laboratory. Beginner's guide to measurement in mechanical engineering GPG This guide aims to explain how a mechanical engineer’s measurements relate to the national standards and to encourage good measurement practice to help make the best measurements possible.
