USE OF MARKING SYMBOLS 4.1 In view of the wide variety of parts used in substantially different assembly situations, this docu

27、ment does not prescribe the location, or method of marking; however, the following guidelines should be followed: 4.1.1 Proper marking allows suitable recycling procedures to be used at end of life. 4.1.2 Wherever practicable, the marking should be located so that it is visible in its “in use” posit

28、ion. Consideration should be given to the use of multiple markings on large or complex-shaped parts. 4.1.3 From the standpoint of field service people, marking on the outside surface of the part (in an unobtrusive location from the viewpoint of the owner) is preferred. 4.1.4 Markings applied with in

29、ks, dyes, or paints, should not bleed, run, smudge, or stain other materials which can come in contact with the marking. 4.1.5 Marking should be designed to remain legible during the entire life of the part. 4.1.6 Markings which are molded into the part are preferred since they are permanent and do

30、not require separate manufacturing operations as do those applied to the surface of the part after molding. Molded in markings should not create a stress concentration site which could result in premature cracking of the part. 4.1.7 The recommended practice for the standard marking symbol (Figure 1)

31、 is consistent with ISO 11469 and VDA 260. Dimensions are suggested guidelines. Markings should be proportional to part size. FIGURE 1 - STANDARD MARKING SYMBOL 4.1.8 Examples See Figure 2. FIGURE 2 - EXAMPLES OF STANDARD MARKING SYMBOLS SAE J2332 Revised JUL2013 Page 6 of 9 4.1.9 For small parts th

32、at cannot accommodate the 3.0 mm letter guidelines, the use of smaller letters should be considered in lieu of not marking the part at all. 4.2 For parts using rubber materials containing 10% or more by mass fibers/ reinforcing materials (see Appendix D list), use the same designation for the “famil

33、y name” as defined in Table 1 and, in addition, alpha codes from ISO 1043-2, followed by a numeric value representing the nominal percentage of fiber/reinforcer. The polymer family codes shall be separated from the fiber/reinforcement codes and value by use of a hyphen. 4.2.1 Examples See Figure 3.

34、FIGURE 3 - EXAMPLES OF STANDARD MARKING SYMBOLS FOR RUBBER WITH FIBER OR REINFORCEMENT LEVELS 10% BY WEIGHT 4.3 Parts fabricated from a blend of two or more elastomeric materials, some of which are not readily visible, may be marked so the primary visible material is identified first followed by the

35、 identification of the other elastomeric material(s) where the individual identification(s) is separated by a comma. Identify the main mass elastomeric component by underlining. A formulation must contain at least 7 parts per hundred rubber (PHR) of any elastomeric component, based on total elastome

36、r content, to be considered a blend. If used, the fiber/ reinforcement referenced in Section 4.2 must be identified regardless of total content. 4.3.1 Examples For a product made of two components, see Figure 4.
