35、es. 4 General specifications 4.1 General principles To assess whether a stone type is suitable for a particular application, a specific testing program is described as mentioned in Table 1. Table 1 contains a detailed overview of the most useful tests, in particular: characterization tests (or ident

36、ification tests): they are used to determine the intrinsic material properties, independent of its transformation into a finished product and the environment in which it will be used; tests relating to performance in use: these tests evaluate the performance of the finished product after manufacturi

37、ng. Therefore, these tests should as nearly as possible reproduce the physical PD CEN/TR 17024:2017CEN/TR 17024:2017 (E) 8 forces and effects of weathering and contamination that act upon the element in service (taking into account dimensions and surface conditions); durability tests: these tests ar

38、e used to analyse the behaviour of the stone over time and thus make it possible to evaluate the stability of the intrinsic material properties and of the initial performance data after a period of time. Additionally it is relevant to consider the performance of the same stone type in existing examp

39、les of its use under similar climatic conditions.

46、characterization record/sheet reserved to the origin of the stone shall mention, according to EN 12440: the name and the address of the supplier of the stone product; the commercial name of the stone; the petrographic nature of the stone according to the standards EN 12407 and EN 12670; the place of

47、 origin (as precise as possible, e.g. country, city, GPS data); the macroscopic description of the appearance (colour, texture, etc.). 4.2.2 Petrographic analysis Petrographic characterization (see EN 12407) allows the determination of the mineralogical composition of the natural stone. Based on thi

48、s information, the correct geological name of the stone can be deduced. According to EN 12440, the name of the stone should state the place of origin, the (geological) type and the colour of the stone. In this context, correct petrographic identification of the stone is important and should prevent

49、the use of misleading names. Besides these geological features, a petrographic analysis can also provide useful information concerning the sensitivity of stone in specific conditions (micro cracking, formation of expansive minerals, oxidation of metallic minerals, etc.). 4.2.3 Visual characteristics: reference sample Stone is a natural material; its colour, veining and texture can vary. Therefore, the general visual characteristics should be defined by means of a reference sample. A reference sample shall comprise an adequate numbe
