| Zusammenfassung | A study evaluating the benefits of storing stainless steel mass standards for 6-months in nitrogen compared with storage in air has been undertaken at three National Measurement Institutes. X-ray photoelectron spectroscopy results showed little difference between storage in air for 6-moths and storage in nitrogen. Gravimetric weighing results showed excellent mass stability in the artefacts stored in air compared with significant mass gains in the artefacts stored in nitrogen. |
