| Zusammenfassung | Certified reference materials are an essential tool for calibration of testing equipment, validation of analytical methods and ensuring quality of test results. Due to lack of national low temperature reference materials, Decahydronaphthalene reference material for flash point measurements according to ISO 13736has been developed by the National Metrology Institute of Egypt (NIS). This article describes production steps of the reference material. Certification of the material was carried out by interlaboratory comparisons, where between bottles homogeneity and stability studies were conducted in explosion protection department at PTB, Germany. The interlaboratory results were statistically analyzed, and robust mean was calculated as assigned value. The certified value and expanded measurement uncertainty (k = 2) was found 55.7 °C ± 1.2 °C, respectively. |
