For first-sample release of small parts,e.g., threaded fastening elements, a test production of > 50 kg shall be performed.The coating materials must not contain any Cr(VI) compounds in order to ensure that the resultant coatings are likewise Cr(VI)-free.Unless certain sections of a part that are marked in the drawing are excluded from the surface coating, the entire surface of the parts must comply with the required surface protection type and display the prescribed properties. There shall be firm adhesion between coatings and base material (see Section 3.10); there shall be no flaking of the coating or cracks under elastic deformation. The protective coatings must not exhibit any pores, cracks, damage, or other flaws that impair the corrosion protection and/or function.The production process and its control shall not impair the functional characteristics of the finished part. Thus for example, the coating must not flake or crack when the springs or spring washers are mounted or used as intended.With proper mounting, the coating shall not be damaged in a way that would result in impairment of function and/or decrease in the specified corrosion protection.Page 4TL 245: 2004-12The selection of supplier and coating system is subject to agreement with the VW Group Central Laboratory (K-QS-32) and/or the AUDI Group Test Laboratories (I/GQ-32 and N/GQ-55) prior to usage of the given part.3.3 Threaded parts with metric ISO standard threadsThe coating process shall not impair the mechanical and physical properties specified for joining elements. Therefore, the manufacturer has to check whether the baking conditions specified by the coating company are suitable for the parts to be coated.An essential functional property of threaded parts with metric ISO standard threads is their compliance with specified coefficients of friction. In order to ensure that the coefficients of friction comply with VW 011 29, a topcoat with integrated lubricant additive is prescribed for surface protection type Ofl-t647, in addition to the base flake coating.In the case of screws and bolts, the test requirements listed below only apply to the head and/or the wrench bearing surfaces, in the case of nuts, they apply only to the nut body with the exception of the thread. For threaded and similar shaped parts, such as studs, the test requirements only apply to the face surfaces.Reduced requirements (see Sections 3.9 and 3.11.2) apply to process- or geometry-related weak spots of coating areas on joining elements and quick fastening elements.Prior to coating, threaded parts shall exhibit tolerances corresponding to the coating thickness. Metric threaded parts shall preferably be designed according to VW 116 24 (internal threads) or VW 116 27 (external threads). After the coating process, the zero line must not be exceeded in the case of external threads, and it must not be fallen below in the case of internal threads.For further information see VW 011 10, Section 2.3.4 Base coatingRepeated treatment would be useful to produce an even and opaque coating. It is compulsory for barrel coating.The coating system’s corrosion protection performance is enhanced by repeated coating. Type and number of the coating processes for flake coating should be specified in the drawing if this is important for the quality of the basic layer in addition to the specified layer thickness.3.5 Topcoats/lubricant additivesIn order to observe the anti-corrosion requirements and to guarantee the defined coefficients of friction, additional system-specific topcoats, optionally with integrated lubricant additive, may be used. The topcoats must be coordinated to suit the base coating. They must not cause any functional impairment.If, in addition to corrosion protection, further functional surface characteristics such as paintability, compatibility with other agents, friction properties, threading behavior, vulcanizability or temperature behavior are required, part-specific tests or functional tests must be performed.3.6 Base materialSee drawing.Page 5TL 245: 2004-123.7 PretreatmentPrincipally metallically bright. Alternatively (depending on the coating system) micro-crystalline thin layer phosphating (1 to 3 g/m²) is permissible.Prior to coating, hot alkaline and/or mechanical cleaning (e.g. abrasive blasting) shall be carried out on hardened or high-strength steel parts with a tensile strength > 1,000 MPa. Special treatments that could lead to hydrogen absorption are only possible in individual cases upon provision of verification of the process management in coordination with the responsible QA laboratory of the Volkswagen Group.3.8 Dry filmComposition, see International Material Data System (IMDS).3.9 Dry coating thicknessTesting according to DIN EN ISO 1463, DIN EN ISO 2064 and DIN EN ISO 2178; measuring point position for threaded parts with metric ISO standard thread according to DIN EN ISO 4042. Requirement: minimum coating thickness 8 µm; maximum coating thickness 18 µm. If due to the process or geometry, the minimum coating thickness is not achieved, this is permitted as long as the corrosion protection and functionality, e.g. threading behavior, are not impaired.3.10 AdhesionAdhesive tape with an adhesive strength of (7 ± 1) N per 25 mm width is used for the adhesion test acc. to DIN EN ISO 10683. It is firmly pressed onto the specimen surface and then removed with a jerk-like motion perpendicular to the surface. There must be no large-area removal of the coating. Small particles of the coating that adhere to the tape are permissible.3.11 Corrosion behavior3.11.1 Test according to DIN 50017-KK (only for first-sample test)The scribing line is applied on the basis of DIN EN ISO 7253, component dimensions permitting. After a test duration of 720 h and evaluation according to DIN EN ISO 4628-3, the following minimum requirements must be adhered to at all times:base metal corrosion on surface: Ri 0,base metal corrosion permissible in the scribing line, but no rust creep.Page 6TL 245: 2004-123.11.2 Test according to DIN 50021 SSGeneral requirements (not for Ofl-t610 and barrel-coated goods with thread):no base metal corrosion (Ri 0) after a test duration of 720 h without thermal conditioning,no base metal corrosion (Ri 0) after a test duration of 480 h with thermal conditioning for 96 h at +180 °C (for Ofl-t611: +200 °C).Deviating requirement for Ofl-t610:no base metal corrosion (Ri 0) after a test duration of 480 h without thermal conditioning.

With an appropriate layer structure, the zinc flake coatings are able to with‐stand temperatures such as those occurring, e.g., in the engine compartment (for details, see table 1).Since this coating process poses no risk of hydrogen-induced embrittlement, it is preferably used as corrosion protection for hardened and high-strength steel parts with tensile strength values >1 000 MPa or hardness values >320 HV. The protection system must be chosen such that the strength and hardness are not negatively affected by the treatment temperatures.Zinc flake coatings are also suitable for use as a coating for ferrous materials in contact with alumi‐num components (however, not for those in contact with magnesium components).The coating is not suitable for components–that serve as electrical conductors (e.g., ground connections)–inside of engines (e.g., oil chamber) in order to avoid clogging by detached coating particles The coating is only conditionally suitable for components with–triple squares as per Volkswagen standard VW 01043 <N8 and hexalobular sockets as perVW 01048 <T30–hexagon sockets <5 and cross recesses as per DIN EN ISO 4757 <H3–external thread <M6–internal thread <M10–washers with thickness values <1.6 mmDescription See VW 13750, section 2.Requirements Surface protection types The surface protection types listed in table 1 apply. Examples of systems previously released for components are listed in appendix A.1 2 33.1Page 3TL 245: 2014-11Table 13.2General requirementsApproval of first supply and changes as per VW 01155.Avoidance of hazardous substances as per VW 91101.10 finished parts are required for complete testing. For initial sample release of small parts, e.g., threaded fasteners, a test production of >50 kg must be performed.Page 4TL 245: 2014-11The coating materials must not contain any Cr(VI) compounds in order to ensure that the resultant coatings are likewise Cr(VI)-free.Unless certain sections of a part that are marked in the drawing are excluded from the surface coating, the entire surface of the parts must have the required surface protection type with the pre‐scribed properties. The coatings must adhere firmly to the base material (see section 3.10) and the coatings must not chip or crack due to elastic deformation.The protective coatings must not have any pores, cracks, damage, or other flaws that negatively affect the corrosion protection and/or function.The production process and its control must not impair the functional characteristics of the finished part. For example, the coating must not flake or crack when the springs or spring washers are mounted or used as intended.If the coated components are properly mounted, the coating must not be damaged in a way that would negatively affect the function and/or would reduce the specified corrosion protection.The selection of manufacturers and coating systems must be agreed upon with the Volks‐wagen AG Laboratory (GQL-M/1) and/or with the Audi AG test laboratories (I/GQ-31 and/or N/GQ-551) for each individual component before use.Threaded parts with metric ISO threadsThe coating process must not negatively affect the mechanical and physical properties specified for fasteners. Therefore, the manufacturer must check whether the curing conditions specified by the coating company are suitable for the components to be coated.An essential functional property of threaded parts with metric ISO threads is their adherence to specified coefficients of friction. In order to ensure that the coefficients of friction adhere to VW 01129, a top coat with integrated lubricant additive is prescribed for surface protection type Ofl-t647, in addition to the base flake coating. For Ofl-t615, the coefficients of friction as perVW 01129 are ensured by means of additional lubrication as per TL 52165. For the release of new coating systems and the detection of faults in the case of complaints during installation, parts with metric ISO threads must be tested as per VW 01131-1 and VW 01131-2.Metric ISO threads must be designed as per VW 11611. After the coating process, external thread dimensions must not exceed the shaft tolerance zone h in the shaft basis system as per ISO 286and internal thread dimensions must not be below the hole tolerance zone H in the hole basis sys‐tem as per ISO 286.Especially in the case of threaded parts with top coats, it must be ensured that the surfaces are not impermissibly damaged by processes carried out after the coating process, such as 100% part check, packaging, transport, etc. For more information, see the guideline "Berücksichtigung der Schütt- und Transportprozesse bei der Umstellung auf Cr(VI)-freie Oberflächen" ("Consideration of Dumping and Transport Processes During the Changeover to Hexavalent-Chromium-Free Surfa‐ces"), published by Deutscher Schraubenverband e.V. (German Fasteners Association). Rework must always be announced and agreed upon.For further information, see VW 01110-1, section 3.Base coating The base coating contains a binding agent and approx. 70% zinc flakes and approx. 10% alumi‐num flakes. The use of zinc dust is not permissible. In order to reliably achieve coatings that have uniform coverage and that satisfy the test requirements defined in section 3.11.2, a multiple-coat‐ing process is required.3.3 3.4Page 5TL 245: 2014-11Top coat/lubricant additiveIn order to improve corrosion protection and to achieve the defined coefficients of friction, addition‐al system-specific top coats must be used, optionally with an integrated lubricant additive. The top coats must be matched to the base coating. They must not cause any functional impairment.Zinc flake coatings with top coats must not be used if paintability and the bonding of adhesives (al‐so: locking or adhesive coatings for fasteners) are required.Base materialSee drawing or master data list (MDL).PretreatmentUsually bright metal. Alternatively (depending on the coating system), a micro-crystalline, thin-layer phosphate coating (1 g/m 2 to 3 g/m 2) is permissible.Before coating, hot alkaline and/or mechanical cleaning (e.g., abrasive blasting) must be per‐formed on high-strength and hardened steel parts with tensile strength values >1 000 MPa or hard‐ness values >320 HV.Exceptions are only permissible following agreement with the Volkswagen AG Laboratory (GQL-M/1) and/or the Audi AG test laboratories (I/GQ-31 and/or N/GQ-551).Dry filmComposition as per International Material Data System (IMDS).Dry film thickness Testing as per DIN EN ISO 1463, DIN EN ISO 2064, and DIN EN ISO 2178; position of measuring points for threaded parts with metric ISO thread as per DIN EN ISO 4042.The average minimum coat thickness must be 8 µm; the results of the individual measurements may vary within the range from 6 µm to 20 µm. For threaded parts, the specifications only apply to the head and/or to the face surface and wrench bearing surface; for all other surfaces, the mini‐mum coating thickness is achieved if the anti-corrosion requirements are fulfilled.Driving recesses and threaded areas must not have any base coat and/or top coat accumulations that might negatively affect the functional properties.AdhesionA scribing line based on DIN EN ISO 9227 is applied if the component dimensions allow. Adhesive tape with an adhesive strength of (10 ±1) N per 25 mm in width is then used for the adhesion test.The tape is firmly pressed by hand onto the specimen surface and then removed with a sudden motion perpendicular to the surface. Coating must not be removed from a large area. Small parti‐cles of the coating that adhere to the tape are permissible.NOTE 1: Suitable adhesive tape for the test is, e.g., "Tesaband 4657".NOTE 2: In the case of small parts, the adhesion test can be performed without a scribing line.3.5 3.6 3.7 3.8 3.9 3.10Page 6TL 245: 2014-11Corrosion behavior Test atmosphere: Condensation atmosphere with constant humidity (CH) as perDIN EN ISO 6270-2This test is only required for the release of new coating systems. Usually, this test is carried out on coated test panels (for the test scope, see below). Within the framework of an initial sample inspec‐tion, the moisture resistance can also be proven by a certificate issued by the coating material manufacturer.A scribing line based on DIN EN ISO 9227 must be applied. After a test duration of 720 h and eval‐uation as per DIN EN ISO 4628-3, the following requirements must be satisfied in each case as minimum specifications:–Base metal corrosion on surface: Ri 0–Base metal corrosion permissible in the area of the scribing line, but no corrosion creepageNatural salt spray (NSS) test as per DIN EN ISO 9227The following requirements apply to parts in the Receipt of Goods department of the Volkswagen Group plant using the parts (i.e., after packaging and transport).NOTE 3: Usually, the base coat must be applied 3 times in order to safely achieve ≥600 h of re‐sistance to salt spray fog without base metal corrosion.Requirements for components of a general nature–No base metal corrosion (Ri 0) after a test duration of 720 h –No base metal corrosion (Ri 0) after a test duration of 480 h with thermal aging (heat aging/re‐circulated air) 96 h at +180 °CRequirements for threaded barrel plated goods–No base metal corrosion (Ri 0) after a test duration of 600 h without thermal aging –No base metal corrosion (Ri 0) after a test duration of 480 h with thermal aging (heat aging/re‐circulated air) 96 h at +180 °CRequirements for components with surface protection types Ofl-t601, Ofl-t610, andOfl‑t615–No base metal corrosion (Ri 0) after a test duration of 480 h without thermal agingChemical resistance The verification of the resistance to chemicals is only required for the release of new coating sys‐tems. Usually, this test is carried out on coated test panels (for the test scope, see below). As part of the initial sample inspection, resistance to chemicals may also be demonstrated by a certificate issued by the coating material manufacturer.Testing is performed as per DIN EN ISO 2812. The evaluation is performed as perDIN EN ISO 4628-1.
