Instrument calibration.
The main thing to remember is that measurement uncertainty must encompass everything from NIST to the final laboratory result. Every source of error along the way must be accounted for. Our vendors do much of it for us, but we must make sure they are doing their job properly. We must make certain our vendors have performed rigorous uncertainty analyses and are performing in accordance with them. ISO 9001-2000 and 17,025 accreditations can eventually help offer us assurance in this area.
