President, NIST Liaison

Company: NIST

Mrs. Dawn Cross has worked at the National Institute of Standards and Technology (NIST) in the Thermometry Group since 1994. Mrs. Cross is responsible for the Industrial Thermometer Calibration Laboratory (ITCL) calibration of industrial platinum resistance thermometers, thermocouples, thermistors, digital thermometers, and organic liquid-in-glass thermometers over the range of -196 °C to 550 °C. As part of her responsibility for the ITCL, Mrs. Cross maintains the NIST quality system documentation and measurement assurance to maintain compliance with the NIST QMs and ISO/IEC 17025;2017. Mrs. Cross started being a NVLAP assessor in 2005 for NIST and 2008 for outside laboratories.

When not performing calibrations, Mrs. Cross performs temperature research related to the uncertainty of industrial thermometer calibrations and finding alternatives to Hg-in-glass thermometers. Additionally, Mrs. Cross performs NIST technical assessments covering the areas of temperature (contact and non-contact), ceramics, pressure and vacuum and fluid flow.

In order to maintain visibility and protect the interests of NIST and U.S. industry, Mrs. Cross serves on several national standards committees within ASTM E20 (Thermometry) and committees within NIST. She is the Sub-Chairman for ASTM E20.03 Resistance Thermometers, and a member of ASTM D.02 Petroleum Committee. Mrs. Cross is also the Division Safety Representative and a member of the Environmental Management Services Committee.

Membership on the ASTM committees is used to help write thermometry standards and guidance documents for U.S. industry, while the NIST positions are used to help NIST technical staff find suitable replacements for Hg-in-glass thermometers.

Mrs. Cross has taught courses at the Measurement Science Conference, March 2010, 2011, 2013, 2014, 2015, 2016, 2017 covering SPRT’s, LiG’s, PRT’s, Thermistors, Assessing Labs. NVLAP Assessor training received from Pi Group, NVLAP, and SSD Quality Manager.
