Find the most up-to-date version of VDA at Engineering Works Standards. Material Labelling of Components for Vehicles in accordance with VDA General Instructions. June VN VDA - Components of motor vehicles Marking of material - Others.

The marking must be applied to an appropriate location so that the quality and appearance of the product is not negatively affected. A single marking is sufficient for original parts that are from the vehicle brands of the Volkswagen Group and are only sold as assemblies. If the parts of an assembly are also sold individually, then these parts must also be marked. It is permissible to omit a marking only if — — it is technically impossible to apply e.

On the drawings, cross out the markings that are not to be added, starting from the bottom see figure 1. Figure 1 — An example of a partial marking the part number, date marking, and material marking are not to be included due to a lack of space Alternative parts marking can be specified by the appropriate design engineering department upon agreement with the Quality Assurance and Standards departments.

Additional notes for application, requirements, examples, dimensions, etc. Page 5 VW Figure 2 — Example of a type approval mark with approval number 6. The marking requirement on the drawing for this purpose is preferably to be positioned below the text macro VW , NO-E2 see figure 4. Recommended size: The size, type, and position of the CCC mark must be agreed upon before the tool release, as part of the responsibility of the supplier, with the regulating authority "Certification and Accreditation Administration of the People's Republic of China CNCA ".

Likewise, vehicles with relevant parts that are not properly certified and marked are not permitted to be registered for or introduced into the Chinese market. After successful CCC certification audit of the production location and product test , the CCC mark and the corresponding CCC factory code must be applied to the parts as per the valid certification requirements. Page 4 VDA April Caution: It is compulsory to mark plastic parts and elastomer components exception: tires ac- cording to sections 4.

The decisive aspect: Is the purpose of this material data sheet achieved according to section 1? To ensure improved legibility, spaces may be inserted between the individual blocks or letters and figures of a marking. However, spaces are not counted as characters and omitted when the codes are used for automatic data processing. It is also recommended to mark parts weighting less than g. The marking is set up according to the internationally agreed code and brief type designations in accordance with ISO -1, -2, Marking of softening agents according to ISO is dis- pensed with when health risks can be excluded and there are no known limitations with regard to recycling.

Page 5 VDA April 4. The main component, i. The new material grades can then be included in the material data sheets.

In general, materials that are not yet in the data sheet collection may also be used. The data sheets are supplemented within the scope of release testing.

There is a test plan in the appendix of the TL as per the example of a test plan — section A. The purpose of the test plan form is to increase the clarity of the initial. Marking must be carried out as per these standards.

The markings for the released material qualities must be obtained from the corresponding material data sheets. The surface and interior of the components must be free of flaws and processing defects, such as flow lines, voids, cracks, or similar faults. Sink marks at the base of ribs and reinforcements are permissible only if they do not adversely affect the part's function or appearance.

Where necessary, deviating conditioning processes are described in the respective material data sheets. The mechanical material data specified in a material data sheet are valid only for the material type of one or more suppliers that has been evaluated positively in terms of the material and released by the laboratory as per section 1.

The general requirements apply to every material quality and material combination. Mechanical properties described in the material data sheets may vary depending on additional requirements. In every case, both the general requirements and the material-specific requirements must be met in order to describe the material quality actually used also see the example test plan in section A. Deviating temperature limits must be determined if.

See section 5.


Visual impairments are also not permissible in the visible area. The temperature level in the forced air oven is based on the temperatures to which the finished part will actually be subjected. The aging behavior depends greatly on the material used and is therefore described in the relevant material data sheet if required. During aging, stabilizers must not alter the color of the component's surface. Table 1 Kalahari test as per PV 1-year cycle For vertical components A visual evaluation is performed.


Kalahari test as per PV 2-year cycle Only for components that sit horizontally A visual evaluation is performed. The components must not exhibit any changes to their shape. As per TL 4. Florida test as per PV 1-year cycle For vertical components A visual evaluation is performed. See table 1.

As per TL 5 Notes on testing 5. Page 5 TL Florida test as per PV 2-year cycle Only for components that sit horizontally A visual evaluation is performed.

No changes in shape. Page 6 TL As soon as there are substantially visible changes under heat. Should visible residues still remain. Aging period: Aging temperature: For this purpose.

Chargeable Order

The components are then visually evaluated only if required in the material data sheet. After removal.

For encapsulations over the entire area. In this case. If the wall thickness of the soft encapsulation is too low for a test. Three test specimens.

Determining tensile strength and elongation at tear on thermoplastic elastomers as per DIN Dumb-bell specimen: Traverse speed: Page 7 TL If the whole surface of hard component is completely encapsulated.

The specimens manufactured in this manner must then be clamped in the tensile test machine e. Specimen thickness: Reading time: The tensile test for the aged specimens is conducted as described above after conditioning the specimens at room temperature. Vehicle Parts. Page 8 TL PV Vehicle Parts. Only the following points must be noted: For molded components..

Weathering in Moist. Standards whose titles are given in German may be available only in German. Adhesive-Coated on Both Sides.

For xenon arc light aging. For heavily tapered parts at the injection ends e. To enable a better evaluation of the processing characteristics. Editions in other languages may be available from the institution issuing the standard. Weathering in Dry. Specimens must be clamped in the supports of the xenon arc light aging devices such that the soft lip is the exposed side. Some of the cited documents are translations from the German original.

In the process. Symbols and abbreviated terms.Preface Material markings for components of motor vehicles have the exclusive purpose of optimum, type-specific recycling with reference to the material cycle.
