For further instructions, see Annex D.5 Composition of complete graphical symbol
47、for areal surface texture5.1 GeneralIn order to ensure that an areal surface texture requirement is unambiguous, it is necessary, in addition to the indication of both a surface texture parameter and its numerical value, to specify additional requirements (e.g. type of scale limitation, transmission
48、 band, type of filters, manufacturing process, surface lay and possible machining allowances). It may also be necessary to set up requirements for several different surface texture parameters in order that the surface texture requirements ensure the functional properties of the surface. (Examples of
49、 indications of areal surface texture requirements are given in Annex C.)5.2 Positions of surface texture requirementsThe mandatory positions of the various surface texture requirements in the complete graphical symbol are shown in Figure 2.Figure 2 Positions of surface texture requirements in the complete graphical symbolThe complementary surface texture requirements in the form of surface texture parameters numerical values, and a transmission bandshall be located at the specific positions in t
