TL;DR: In this article, a detailed analysis of the spectra of adsorbed nitrogen isotopes was performed and it was shown that at low surface coverage, the nitrogen molecules are adsored at remote positions (singletons) at high surface coverage.

TL;DR: In this article, an attempt is made to base the selection on a quantitative approach by using a mathematical model supported by the probability theory, which is based on the selection of appropriate electric equipment.
Abstract: With regard to the classification of hazardous areas and the selection of appropriate electric equipment, there are discrepancies between the electrical codes of various countries and their interpretation. Work on intemational standardization of constructional requirements of apparatus is proceeding. However, there is no common opinion as to what type of equipment protection should be applied under specific circumstances. This is due to the fact that these circumstances are merely qualitative concepts. An attempt is made to base the selection on a quantitative approach by using a mathematical model supported by the probability theory.
