Description3.1 The system is based on standard symbols for terms relating to plastics published by the InternationalOrganization for Standardization (ISO 1043). Mo
10、st commonly used symbols, including some not covered byISO, are shown in Table 1. In addition, symbols for commercial plastic blends are shown in Table 2, andsymbols for commonly used automotive fillers/reinforcements derived from ISO 1043-2 are shown in Table 3.3.2 If additional symbols are require
11、d to cover new materials, the form in Appendix A shall be completed andsubmitted to SAE. New symbols will be included in the next revision to this document.4. Use of Marking Symbols4.1 In view of the wide variety of parts used in substantially different assembly situations, this document does notpre
12、scribe the location, and/or method of marking; however, the following guidelines should be followed:4.1.1 Field service people should be informed regarding the material from which the part is made so suitable repairand paint procedures may be used.4.1.2 Wherever practicable, the marking should be lo
13、cated where it may be observed while the part is in use.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 unobtrusivelocation from the viewpoint of the ow
14、ner) is preferred.4.1.4 Markings applied with inks, dyes, or paints should not bleed, run, smudge, or stain other materials which maycome 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 ar
15、e preferred since they are permanent and do not require separatemanufacturing operations as do those applied to the surface of the part after molding. Molded in markingsshould not create a stress concentration site which could result in premature cracking of the part.4.1.7 The recommended practice f
16、or the standard marking symbol is as shown in Figure 1. Dimensions aresuggested guidelines. Markings should be proportional to part size.FIGURE 1STANDARD MARKING SYMBOLCopyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without lice

18、, in addition, alpha codes fromISO1043-2, followed by a numeric value representing the nominal percentage of filler/reinforcer.

20、ion(s) is separated by a comma. The main component by mass isidentified by underlining.4.3.1 EXAMPLESFor a product made of three components, the visible one is a thin coating of poly (vinyl chloride)over a polyurethane containing an insert of acrylonitrile/butadiene/styrene that is the major compone
