Note 2 to entry: A delivery may include one or several batches. 4 General specific

35、ations 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 identification tests): they

36、 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 manufacturing. Therefore, these t

37、ests 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 are used to analyse the

38、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 examples of its use under s

39、imilar climatic conditions.

46、d/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 origin (as precise as

47、 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 this information, the cor

48、rect 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 the use of misleading

49、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 number of pieces of n
