2 Description
2.1 Code structure
The abbreviation for surface protection ('Ofl-' from the German word for 'surface') is followed by acode with four characters, taken from Table 2.
2.2 Example of description
Surface protection: electrolytic zinc alloy coating, transparent Cr(VI)-free passivated, with lubricanttreatment, heavy protection, according to TL 244.
VW 137 50 – Ofl-r645
3 Requirements
3.1 General requirements
The vehicle parts and units are categorized according to their corrosion load and assigned toa protection class with grade (according to Table 1) by the responsible Engineering Department
upon agreement with the Volkswagen AG Central Laboratory (K-QS-32) and/or the AUDI AGTest Laboratory (I/GQ-322).
Table 1 – Classification of vehicle parts
Vehicle part categories Corrosion load Protection class
Parts with the following features:(a) non-visible in installed condition,(b) corrosion protection serves onlyas protection for transportation,(c) corrosion protection is not neededfor proper performance.
Minor load. Light protectiongrade 1
Interior and exterior componentsin a protected installation position.
Not for joining elements (for exceptionssee VW 011 10).
Medium load. Medium protectiongrade 3
Parts that are subjected to direct open-airweathering (e.g. chassis, engine,transmission).
Parts that are visible in installed condition(also seen from the vehicle underside).Parts with the following features:(a) corrosion protection is required
to ensure proper performance and(b) use in the interior and exterior dueto reduction of material types policy,e.g. joining elements.
Heavy load. Heavy protectiongrade 6

Page 4VW 137 50: 2005-02
The restrictions stipulated in VW 603 61 must be observed for mechanical joining elements.
The following standards apply to thread dimensions prior to surface treatment: VW 116 10,VW 116 14, VW 116 24, VW 116 25 and VW 116 27. For thread dimensions after surfacetreatment, VW 116 11 and VW 116 15 apply.
All-metal clamping nuts must always be treated with additional or integrated lubricants.Avoidance of hazardous substances according to VW 911 01. The coatings used must be free ofcompounds containing Cr(VI) or lead.
3.2 Drawing specifications
If a certain surface protection is required for the entire part or for several parts in an ASSY, thecode shall be entered in the surface protection title block; e.g. Ofl-t650 (see also VW 010 58). Ifseveral surface protection types can be applied optionally, the codes for all permissible treatmentsshall be given,
e.g. Ofl-r673/x630.
If only partial protection is applied to a part, “see drawing” shall be entered in the surface protectiontitle block; a wide dash-dot line with a datum line (see Figure 1) marks the given area on the part.
If there is only a small area on the part that is without surface protection, the unprotected area shallbe marked (Figure 2). In this case “see drawing” shall be entered in the surface protectiontitle block.
Figure 1 Figure 2
If different surface treatments are required for a part, “see drawing” shall be entered in the surfaceprotection title block. The given areas on the part shall be clearly indicated.
If parts from one ASSY are separately coated (one or more different surface treatments), “seedrawing” shall be entered in the surface protection title block of the assembly drawing. The surfacetreatments shall be referred to separately in the part-related drawings.
3.3 Weldability
If parts with surface protection are to be welded to each other or to other metal parts, the partsshall be tested for weldability. Ofl-c340 shall be provided as the standard surface protection.
3.4 Agents impairing wetting ability
Lubricants and slushing oils shall be free of silicone oils and other agents that significantly impairwetting ability.

Page 5VW 137 50: 2005-02
3.5 Friction behavior
The influence of the surface protection on the friction behavior, particularly for parts with metricISO thread, shall be determined by testing and matched to the performance characteristics.
The total coefficient of friction of a test batch with surface protection type b140 and with allsurface protection types with additional or integrated lubricant treatment shall be in the rangefrom 0.09 to 0.15 (except for joining elements with adhesive or locking coating as well as tappingscrews, Powerlock ® screws and clamping nuts [all-metal and PA ring]).
3.6 Zinc coatings
Electrolytically deposited or electroplated coatings are not permissible for high-strength steel and/orstandard parts with a tensile strength of Rm > 1,000 MPA and threaded parts with a propertyclass of 10.9.
Exceptions are possible for components that are only subjected to pressure.
Zinc flake coatings according to code letter t shall preferably be used.
Only in exceptional cases when electrolytically deposited zinc coating or zinc alloy coating isabsolutely necessary for functional reasons can these coatings be applied with integrated heattreatment according to DIN 50969. The use of such coatings is limited to tensile strength values of1,200 MPa for standard parts (see VW 602 50).
Electrolytically zinc-coated parts or zinc alloy coated parts shall be post-treated in passivationsolutions in order to improve corrosion resistance.
Cr(VI)-free passivated zinc coating systems without additional coatings (paint coats) are, apart fromthe joining elements, only permissible for use in the passenger compartment.
The appearance of zinc/nickel alloy coatings shall be matched to their immediate environment.Only transparent passivation treatment is permissible for electrically conducting connections.
Additional sealing of the coating is a further improvement of the corrosion protection of zinc-coatedparts and zinc alloy coated parts respectively.
3.7 Screws, bolts, nuts, threaded parts and shaped parts
The test specifications according to Table 2 apply to the thread-free areas of screws, bolts, nutsand similar threaded or shaped parts; the next protection class down is applied to the thread andshank.
The application of the protective layers must not result in the h-position being exceeded in the case
of external threads or the H-position being fallen below in the case of internal threads.
3.8 Commercial surface protection types
Commercial surface protection types can be used for less important applications (e.g. steel wire).They are not tested for corrosion resistance however. If this kind of protection is sufficient for apart, the code letter of the method and the digits 010 shall be stated. The description forcommercial coating for example would look like the following: Ofl-x010. Distinction can also bemade between method and finish; e.g. for commercial hot-dip tin coating: Ofl-g020.
The commercial surface protection types, e.g. Ofl-c010 “commercial zinc coating” and Ofl-r010“commercial electrolytical zinc-alloy coating” must not contain any Cr(VI) compounds.

3.9 Parts without surface protection
3.9.1 Joining elements
Parts with the description “bright”, surface protection type “without”, “-” or without any descriptionshall, as indicated in DIN ISO 8992, be supplied in lightly oiled condition. If in exceptional casesunoiled parts must be supplied, this must be indicated in the drawing by means of the entry“not oiled”.
3.9.2 Other parts (e.g. sheets)
QP-A001 applies to parts without surface protection with the description surface protection type“without” or “bright, oiled”. If in exceptional cases unoiled parts must be supplied, this mustbe indicated in the drawing by means of the entry “not oiled”.
3.10 Assignment of surface protection types and codes
The specifications of Table 2 shall apply. Surface protection types represented in bold italics shallpreferably be used for joining elements; surface protection types with a frame are standard surfaceprotection for components without threads.
Surface protection types in brackets contain Cr(VI) and are not available for new designs.
Table A.3 presents the surface protection types according to VW 137 50 that correspond to theprotection types of VDA1 test sheet 235-104. Table A.4 lists all the invalid protection types thatwere included in earlier issues of VW 137 50.
