25、al product documentation Parts lists3 General requirementsIt is recommended that part references be assigned in sequential order (see 4.7).Identical parts shown in an assembly shall have the same part reference.Each complete sub-assembly incorporated in the superior assembly is identified by a singl
26、e part reference.All part references shall be shown in a parts list (see ISO 7573) giving the appropriate information on the parts concerned.4 Presentation4.1 IdentifiersPreferably part references should consist of numerals only. If necessary, they may be augmented by the use of capital letters. The
27、 design, dimensions and spacing of the characters shall comply with ISO 3098-0.It is recommended that the part reference number contain a maximum of three characters.DIN EN ISO 6433:2012-12 EN ISO 6433:2012 (E) 4 4.2 AppearanceAll part references on the same drawing shall be of the same type and hav
28、e the same height of lettering. They shall be clearly distinguishable from all other indications. This can be achieved for example by:a) encircling the characters of each part reference (see Figure 1); in this case, the circles shall have the same diameter and be drawn with continuous narrow lines (
29、type 01.1 of ISO 128-23, ISO 128-24 and ISO 128-25);Figure 1 Encircled-part reference numberb) using characters of a larger height, for example twice the height as used for dimensioning, and similar indications (see Figures 2 and 3).Figure 2 Part reference number written with larger character height
30、Figure 3 Alternative method of indication4.3 Identical partsPart references of identical parts should only be identified once, provided that there is no risk of ambiguity. For exceptions, see Annex A.4.4 LocationPart references shall be placed outside the outlines of the parts concerned.The part ref
31、erence should be connected to its associated part by a leader line (see Figures 1, 2 and 3), the termination of which shall comply with ISO 128-22.Leader lines shall not intersect. They should be kept as short as practicable and should preferably be drawn at an angle to the part reference. In the ca
32、se of encircled-part references, the leader Iine shall be directed towards the centre of the circle.DIN EN ISO 6433:2012-12 EN ISO 6433:2012 (E) 5 4.5 PositioningFor the sake of clarity and legibility of a drawing, part references should preferably be arranged in horizontal rows and/or vertical colu
33、mns (see Figure 4).When several part references use a common leader line, they may be arranged horizontally according to one of following methods illustrating four part references (8, 9, 10 and 11).NOTE Method a) can also be arranged vertically.Methods:a)b)4.6 Related partsPart references of related
34、 parts, e.g. screw, washer and nut, may be identified by a common leader Iine (see Figure 4, parts 2, 3 and 4).4.7 Numbering sequenceA distinct sequence for numbering should be adopted: according to the possible order of assembly; according to the importance of the component parts (sub-assemblies, m
35、ajor parts, minor parts, etc.); according to any other logical sequence.5 ExampleAn example of the application of part references for an assembly is given in Figure 4.DIN EN ISO 6433:2012-12 EN ISO 6433:2012 (E) 6 Figure 4 Use of part references on an assembly drawingDIN EN ISO 6433:2012-12 EN ISO 6
36、433:2012 (E) 7 Annex A (normative) Part references shown with number of partsThe number of parts is specified in the parts list and should be avoided in connection to the part reference number on the drawing.For clarity, the same part reference number may need to be repeated at different locations.
37、The number of parts at each location may also be needed. The part reference number shall then be encircled according to method a) in 4.2 and the indication of number of parts should follow general drawing rules. The number of parts shall be indicated along with the symbol “” in accordance with ISO 1
38、29-1. See Figure A.1.Figure A.1 Part reference shown with number of partsWhen the number of parts is indicated for several part references using a common leader line, method a) in 4.5 shall be used.
