The need to harmonize national and international statistical practices in data collection and presentation is based on the desire for comparability of information. In the Russian Federation and the countries of the European Union, a different approach is used to organize and present the results of statistical observation of the tourism industry, including with respect to the classification of accommodation facilities for tourists, tourist trips according to their purposes. In Russia, they do not collect information on identifying the reasons why the citizens of these countries do not take part in tourism, nor do they register quality characteristics. Analysis of international experience shows that tourism statistics receive a lot of attention, with the focus on polling tourists and collective accommodation facilities. In the Russian system of statistical observation in the field of tourism, despite its constant improvement, there is still an acute shortage of data obtained on the basis of regular sample surveys.

Abstract In this paper it is stated, that a set of quality features of metal matrix composite castings differs from the same set for castings of classic materials, although some features are common for both of these material groups. These features (pertaining to a set of quality characteristics of composite castings) have been named as specific, they have not been determined yet and a description of material quality should be performed (according to the qualitology) on a principle of description of quality characteristics of this product. Therefore, this set of features has been determined. It was proposed to add the following characteristics to the set of specific features of composite castings quality: matrix material, reinforcement material, binding between components and porosity of the composite casting. In this set a sub-set of quality characteristics of composite castings was also determined.
