2.MATERIALS
---
For surface materials and substrates refer to the specific drawings and the relevant individual material DBLs. The technical values of the initial materials shall correspond to the individual material DBLs, e.g.DBL 5450, DBL 5452, DBL 5454, DBL 5455, DBL 5456, DBL 5460, DBL 5462, DBL 5869 etc.For PV 10 to PV 12 (external parts), no surface fleece made from purely vegetable fibres and/or manmade cellulosic fibres may be used (max. 30 % by weight in fibre blend).Note: wherever possible, avoid resins emitting formaldehyde or phenol.

2.MATERIALS (continued)
2.1Fastening and making-up parts
In accordance with drawing. 3.CHARACTERISTICS
3.1General requirements
--The parts shall be free of production defects of any type which would impair the processing and utiliza-tion properties or the appearance. No CFCs shall be used for the manufacture and processing of mate-rials.
Acoustic parts:
The bond between the surface material and the substrate must be even, sufficiently strong (free of dust and fluff) and resistant to ageing. For this purpose, the substrate surface must be suitably conditioned / provided in a form with good gluing capability. Also, the surface material must be turned over and glued at the outside edges with sufficient strength and without disturbing overlaps. The pull-out forces of glued on, riveted or integrated fastening or making-up parts (retainers, clips or similar) must correspond to the specifications on the drawings.
Their shape must comply with the dimensions specified in the drawing or the functional instructions. The bond between cover material and the inside material as well as between the inside material and substrates must be firm enough to ensure that no separation can occur during assembly or use (e.g. as a result of release agent residues).
3.1.1Only for internal components PVs 00 and 01
-The availability of a certificate of testing in accordance with the following method is defined as an over-riding requirement for adherence to the emission values for interior trim materials: DC work instruction for the determination of gaseous and condensable emissions with thermo desorption (refer to DC test instruction PB VWT 709). Test execution: Institut Fresenius Angewandte Festk?rperanalytik, Hauert 9, D-44227 Dortmund.
In particular, in the case of substances listed in the latest edition of the DFG MAK (industrial threshold value) list under "Carcinogenic", categories 1 to 3, as well as under "Pregnancy", categories A and B, and under "Mutagenic", categories 1 to 3, the supplier is required to continuously minimize the concen-tration and emission at least in accordance with the state of the art, even when the values have fallen below the required DBL threshold values.
The supplier is responsible for checking whether the version in his possession is the latest version. For enquiries on threshold values, please apply to Lothar.Kante@https://www.360docs.net/doc/1618233379.html,.
-The materials used shall fulfill the following requirements in their installed state when tested in accor-dance with the test instructions: "Formteile für den Fahrzeuginnenraum - Bestimmung der Abgabe von Formaldehyd, Ammoniak und Phenolen - Me?verfahren in der 1 m3- Kammer“ (draft October 1994,
issued by Arbeitskreis "Kfz.-Formteile - einfache Prüfmethoden“ under the leadership of FhG-WKI,
Bienroder Weg 54 E, D-38108 Braunschweig):
- Formaldehyde emission:initial value max. 0,2 ppm, in equilibrium max. 0,05 ppm
- Phenol emission:max. 0,04 ppm
- Ammonia emission:minimal
Measurements shall be carried out on finished parts under the following testing conditions:
- temperature65 °C
- relative humidity11 %
- cabinet load 2 m2 per m3
- change of air0,5 h-1
The consistency of production with regard to formaldehyde release shall be tested by means of a sim-ple method and documented, e.g. bottle method (determination of formaldehyde release of molded
parts by the bottle method, VDA recommendation 275- DKF, Ulrichstr. 14, D-74321 Bietigheim) or gas analysis method DIN-EN 717-2 (was: DIN 52 368 - Beuth Verlag GmbH, D-10772 Berlin). It is a condi-tion, however, that this value is determined already for the initial sample. For this reason, it must also be indicated on the acceptance test certificate.

5.1Separating force for laminated parts (cover material/substrate)
The test shall be carried out in analogy with the separation test in accordance with DIN 53 357 immedi-ately after the specified storage periods. Test specimens shall be taken in longitudinal, transverse and diagonal directions and must provide a representative cross-section of the complete part.
5.2Climatic resistance tests
Evaluation criteria:
The parts shall not demonstrate any changes interfering with the application in comparison with the as-supplied state (e.g. warping, flattening, deflection, shrinkage and extension of the finished parts (max.
2,5%), detachment of the surface material and of the fastening and making-up parts, glue
embrittlement, blistering, impressions and piercing, waviness, brittleness and cracking, tackiness,
marked swelling, spalling, layer and fiber separation of the substrate or similar.) Weld joints must
remain firm.

5.3Test with resistance to radiant heat
The test is conducted in analogy with DBL 5307.5.2.
Test equipment: refer to DBL 5307.5.2.1
Test specimens and test specimen arrangement: refer to DBL 5307.5.2.2
Changes over DBL: The test is generally performed on specimens in product thickness.
Test execution:
Place the specimen underneath the heat lamp and switch on the heat lamp. The distance of the lamp to the test specimen is selected depending on the required maximum temperatures specified for the relevant product versions. Refer to Table 1.
In the case of external components, radiate the side facing the heat source. The test period is 6 hours for PVs 10 and 11 and 2 hours for PV 12.
Assess the specimens 30 minutes after the end of the test.
Assessment criteria:
Autogenous ignition, detachment of individual layers, material embrittlement, material decomposition;
for further assessment criteria, refer to Section 5.2 of this DBL.

5.TEST METHODS (continued)
5.4 5.4.1Dimensional stability test
on finished part
Test equipment: - Climatic test cabinet
- Altimeter (digital, analogue)
- Engine hood, body etc.
Accessories:Fasteners
Specimen:Assembly part
Number of specimens:1
Preparation:The body parts (e.g. engine hood) shall be prepared before testing by adding boreholes (d = 10 mm) so that measurement is possible on the side of the
assembly part facing the metal sheet. The arrangement, number and marking
of the boreholes (measuring points) shall be determined for the various parts
in accordance with the drawing.
The assembly parts shall be mounted on the prepared body surfaces using all
fasteners.
Storage:Store the body parts with the attached assembly parts at least 24 h before commencement of the test in accordance with DIN 50 014-23/50-2.
Execution:Measure the distances of the assembly part to the body part using an altimeter at the given boreholes before the specified climatic resistance test in accordance
DBL 5463.
Close the boreholes during the simulation e.g. by means of plugs or stickers.
During simulation, store the part in its installed position.
After all climatic resistance tests specified according to DBL 5463 have been
completed, store the body parts with their mounted assembly parts for at least
24 h in standard atmosphere in accordance with DIN 50 014-23/50-2.
Then measure the distances of the assembly parts to the body part by applying an
altimeter to the given boreholes.
Assessment:Determine the difference in the distance (before / after) of the specified
measuring points in mm.
Target:max. ± 10 mm
