Dimensional Metrology 8/5/20152 In October 1999, the directors of the national metrology institutes (NMIs) of thirty-eight Member States of the Metre Convention signed a Mutual Recognition Arrangement (MRA) for national measurement standards and for calibration and measurement certificates issued by national metrology institutes. NIST Quality System

Dimensional Metrology PED Quality System Based on ISO 17025 Primary standard for laboratory accreditation world-wide. PED Quality Manual is quite small – 61 pages with no secondary SOPs. In preparation for 2009 audit, PED had an outside trainer present the standardized 5 day training course for assessors. Technical assessment by metrology students at Butler County Community College.

Dimensional Metrology Quality Event System The quality event log captures complaints, compliments, intercomparisons, and virtually any other events that happen. The system has been very stable, and the activity of the system impressed our assessors, since it is documentation that we actually use the Quality System.

Dimensional Metrology PED Quality System Assessment had 19 actionable findings. Corrective actions accepted by assessment team in March 2009. Final Approval in Summer 2009

The results of the 2009 NIST internal assessments were rejected by SIM in the Fall of 2009. The submission of details of NIST support for calibration systems, international comparisons and documentation of assessor qualifications resulted in acceptance.

Dimensional Metrology Calibration Program The number of division calibration staff has been roughly constant, although there have been more turnover in the last few years. The primary change has been that an increasing calibration load is handled by engineers rather than technicians. The change from fairly simple comparators to more complex automated measuring machines has driven the trend.

Dimensional Metrology Customer Income by Group There are calibrations in each group, but the primary method for providing traceability in 821.13 and 821.14 is SRMs. 821.11 has begun to develop new calibrations for the first time in decades.

Dimensional Metrology Turnaround Turnaround has continued to be a problem. We have had fewer gages and more folders and more income, which is a result of a slow change in the types of gages we calibrate. An increasing part of our workload are one of a kind gages measured on CMMs. These are more complex and expensive, but less efficient types of calibration. On the bright side, we no longer lie as much about estimated calibration time.
12
Dimensional Metrology Calibration Program - AML The AML has proven to be an excellent environment for dimensional measurements. The improvements in temperature control has lowered uncertainties in key areas, and the reliability of the electrical system and general cleanliness has allowed for much longer unattended measurements, increasing our efficiency. The control chart for the M48 and 1020 mm step gage shows dramatic improvement in the long term reproducibility, and nearly no linear dependence which implies superior temperature control.
13
Dimensional Metrology Calibration Changes The tape tunnel has undergone significant upgrades, including new instruments for tape calibrations, ranging systems, and special tests like a mile of optical fiber. Surface finish calibrations will have upgraded instrumentation with new AMETEK / Taylor- Hobson Form Talysurf PGI 1240 Studies of thermal management of manual calibrations found that while thermal isolation is good, lots of air is better. Nearly all workstations have fans.

Dimensional Metrology Calibration Program New Taylor Hobson - Form Talysurf will take over most surface roughness, and large step height calibrations, as well as measuring hardness indenters, and bullet signature profiles for the standard bullets project (SRM 2460). NIST Microform Calibration System for Rockwell diamond indenters: (1) stylus tip; (2) Rockwell indenter; (3) rotary stage; (4) x-y stage.
