5 whentested in accordance with EN 12371. The number of cycles shall be 48. The test shall be carried outto determine the effect of freeze/thaw cycles on performance characteristics(EN 12372 - flexural strength). The specimens shall be in accordance with the appropriate standard.For some specific uses it may be appropriate to use different test cycles, for example freezing inwater, freezing to a lower temperature, or testing specimens embedded in non-porous siliceousgranules or a different number of cycles.
In these cases national specification standards may befollowed but these variations shall be clearly stated in the test report.If there is no requirement for freeze/thaw resistance or no performance has been determined, thenthis shall be stated.Table 5 — Freeze/thaw resistanceClassClass 0Class 1Marking designationF0F1RequirementNo requirements for freeze/thawResistantresistance( 20 % change in flexuralstrength)4.4 Flexural strengthThe producer shall declare a flexural strength in megapascals (MPa) as the minimum value expectedfor individual test specimens when tested in accordance with EN 12372. If no performance has beendetermined this shall be stated.NOTEGuidance on the appropriate breaking load for different classes of use is given in annex B.4.5 Aspects1.1.1 AppearanceStone is a naturally occurring material giving rise to variations in colour, veining and texture, thereforegeneral characteristics of the appearance may be given by one or more specimens (see 4.5.2).4.5.2 Reference sampleA reference sample shall be a number of pieces of kerb of natural stone of sufficient size to i
