The work of preparing International Standards is normally carried out thro
23、ugh ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collabor
24、ates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at
25、 least75%of the member bodies casting a vote. International Standard ISO13565-2 was prepared jointly by Technical Committees ISO/TC57, Metrology and properties of surfaces, SubcommitteeSC1, Geometrical parameters Instruments and procedures for measurement of surface roughness and waviness, ISO/TC3,
26、Limits and fits and ISO/TC10, Technical drawings, product definition and related documentation, Subcommittee SC5, Dimensioning and tolerancing. ISO13565 consists of the following parts, under the general title Geometrical product specifications (GPS) Surface texture: Profile method; Surfaces having
27、stratified functional properties: Part 1: Filtering and general measurement conditions; Part 2: Height characterization using the linear material ratio curve; Part 3: Height characterization using the material probability curve.

29、) standard and is to be regarded as a General GPS standard (see ISO/TR14638:1995). It influences chain link2 of the chain of standards for roughness profile. For more detailed information of the relation of this part of ISO13565 to other standards and the GPS matrix model, see Annex A. This part of
30、ISO13565 defines a set of parameters, based on the linear material ratio curve, to be used for the evaluation of the valley suppressed roughness profile defined in ISO13565-1. It is based on a three-layer surface model, evaluating the peaks, the core and the valleys separately. 1 Scope This part of
31、ISO13565 describes the evaluation process for determining parameters from the linear representation of the material ratio curve (also referred to as the Abbott curve) which describe the increase of the material portion of the surface with increasing depth of the roughness profile. They are intended
32、to aid in assessing the operational behaviour of highly mechanically stressed surfaces. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO13565. At the time of publication, the editions indicated were val

36、e protruding peaks and deep valleys (see Figure 1). 3.1.1 core roughness depth, Rk depth of the roughness core profile (see Figure 1) 3.1.2 material portion, Mr1 level, in percent, determined for the intersection line which separates the protruding peaks from the roughness core profile 3.1.3 materia

38、ier values on this parameter. 3.3 reduced valley depths, Rvk average depth of the profile valleys projecting through the roughness core profile NOTEThe averaging process in clause4 reduces the effect of outlier values on this parameter. 4 Determination of parameters 4.1 Roughness profile The roughne
39、ss profile used for determining the parameters which are the subject of this part of ISO13565 shall be calculated according to ISO13565-1. 4.2 Calculating the parameters Rk, Mr1, Mr2 The equivalent straight line, calculated according to4.3, intersects the abscissae Mr=0% and Mr =100% (see Figure 1).
40、 From these points two lines are plotted to the x-axis, which determine the roughness core profile by separating the protruding peaks and valleys. The vertical distance between these intersection lines is the core roughness depth Rk. Their intersections with the material ratio curve defines the mate
41、rial ratios Mr1 and Mr2.ENISO13565-2:1997 2 BSI 04-1999 4.3 Calculating the equivalent straight line The equivalent straight line is calculated for the central region of the material ratio curve which includes40% of the measured profile points. This “central region” lies where the secant of the mate
42、rial ratio curve over40% of the material ratio shows the smallest gradient (see Figure 1). This is determined by moving the secant line for %Mr =40% along the material ratio curve, starting at the Mr=0% position as in Figure 1. The secant line for%Mr =40% which has the smallest gradient establishes
43、the “central region” of the material ratio curve for the equivalence calculation. If there are multiple regions which have equivalent minimum gradient, then the one region that is first encountered is the region of choice. A straight line is then calculated for this “central region” which gives the
44、least square deviation in the direction of the profile ordinates. NOTETo ensure the validity of the material ratio curve, the class widths of ordinates of the roughness profile should be selected to be small enough for at least10 classes to fall within the “central region”. With surfaces having very
45、 small roughness or having an almost ideal geometrical plateau, such a fine classification may no longer be meaningful, because of the limited resolution of the measuring system. In this case the number of classes used in the calculation of the equivalent straight line should be stated in the test r
46、esults. 4.4 Calculating the parameters Rpk and Rvk The areas above and below the region of the material ratio curve which delimits the core roughness Rk are shown hatched in Figure 1. These correspond to the cross-sectional area of the profile peaks and valleys which protrude out of the roughness co
47、re profile. The parameters Rpk and Rvk are each calculated as the height of the right-angle triangle which is constructed to have the same area as the “peak area” or “valley area” respectively (see Figure 2). The right-angle triangle corresponding to the “peak area A1” has Mr1 as its base, and that
48、corresponding to the “valley area A2” has100% Mr2 as its base. NOTEThe parameters according to this part of ISO13565 should only be calculated if the material ratio curve is “S” shaped as shown in Figure 1 and Figure 2 and thus has only one single point of inflection. Experience has shown that this
49、is always the case for lapped, ground or honed surfaces. 5 Parameter specification on drawings The parameters in this part of ISO13565 shall be specified on engineering drawings according to ISO1302.
