ITS-90 Fixed-Point Cell Mini-Workshop



The ITS-90 Fixed-Point Cell Mini-Workshop is scheduled to be given at the NIST Platinum Resistance Thermometry Laboratory during the week of February 28 – March 4 2011. Two identical workshop sessions will be offered, each lasting two days. The first session will be held on February 28 and March 1, and the second session on March 3 and 4.   The workshop is designed to provide intensive "hands-on" laboratory training in the realization of ITS-90 fixed-point cells.  Using standard platinum resistance thermometers (SPRTs), participants will measure the freezing, melting and immersion curves of the ITS-90 fixed-point cells over the range from the mercury triple point to the zinc freezing point. Additionally, part of the course will focus on the development of uncertainty statements for the fixed-point cells and subsequently SPRT calibrations.   Time will be split between laboratory (85%) and lecture (15%) sessions.  The Workshop runs from 0830 h to 1700 h each day.  


The workshop is intended for calibration laboratory personnel who are familiar with using SPRTs and/or have taken the NIST Precision Thermometry Workshop.  The participants should each bring a hand-held calculator.   Participation is limited to 4 persons per workshop on a first-come, first-serve basis.  Additional workshops will be held quarterly on an as-needed basis (four wait-listed participants).  


The registration fee is $1,200 per participant, per workshop and includes  workshop materials and a training certificate. The registration fee must be prepaid in order to guarantee your participation in the workshop.  In the case of cancellation, the fee will be refunded only if a replacement is found, or if the cancellation notice is received at least 30 days prior to the workshop.
