Before attending the Intermediate seminar, a metrologist must have completed the Basic Metrology seminar and State participants must have completed required Basic LAP problems. An understanding of the Basic seminar material is assumed for the Intermediate seminar, which is primarily a classroom seminar, although demonstrations and hands-on exercises are used. The Intermediate seminar is generally open to all interested parties; however, State metrologists are given priority in attendance due to legal metrology obligations. This seminar should provide metrologists with a thorough understanding of the theory and concepts behind the procedures and equations used in mass, and volume calibrations. Derivation of many of the equations is demonstrated to provide the metrologists with an understanding of the physics behind the corrections made in high precision calibration.
Topics covered in the Intermediate seminar are:
Air buoyancy corrections and the calculation of air density are covered in detail because these calculations are required in all high precision mass and gravimetric volume calibrations.
After this seminar, the metrologist should have a complete understanding of the theory behind the test procedures and the corrections involved in high precision calibration. The metrologist should be able to compute the magnitude of corrections before performing a calibration to determine if a correction is significant or negligible. This knowledge permits the metrologist to perform the highest precision calibrations possible using the available standards and laboratory equipment. Intermediate LAP problems are assigned to State metrologists at the completion of the course. Acceptable completion of the problems is required for NIST Weights and Measures Division laboratory recognition of the State laboratory in support of fine accuracy mass calibrations and gravimetric volume calibrations.
A NOTEBOOK PC IS NOT REQUIRED FOR THE INTERMEDIATE SEMINAR BUT MAY BE USED AND IS RECOMMENDED!!! A scientific calculator (minimum 10 digits) and familiarity with its operation is required.
The fee for 2012 is $1,795 which does NOT include meals, lodging or travel expenses. State weights and measures metrologists are funded by NIST OWM.

The Washington Metrorail (light rail system) is available from National Airport (awkward with much luggage). You must purchase a ticket at the National Airport Metro station for the entire trip. Take the Blue Line from the airport, change to the Red Line at Metro Center station and take the Red Line to the last stop at Shady Grove, then take a cab to the hotel. Taxis are also available at a cost between $40 and $50. You may also rent a car if you so desire. Many of the local hotels have a shuttle to and from NIST. Please verify if your hotel has shuttle service to NIST when making room reservations.
