Scope
This standard applies to the identification of general surface protection types of vehicle parts and units in drawings and technical documentation. Separate Technical Supply Specifications (TL stan-dards) apply to special surface protection types without identification by surface protection code (see Appendix A.2.). 2 Description 2.1
Code composition
The abbreviation for surface protection ('Ofl-' from the German word for 'surface') is followed by a
4-digit code taken from Table 2.
2.2
Description example
For surface protection: zinc alloy electroplated, heavy protection, transparent Cr(VI)-free pas-sivated, sealed and with lubricant treatment, according to TL 244.
VW 13750 - Ofl-r645
3 Requirements
3.1
General requirements
The vehicle parts and units are categorized according to their corrosion load and assigned to a resistance class with grade (according to Table 1) by the responsible Engineering Department u-pon agreement with the Volkswagen AG Laboratory (GQL-LM) and/or the AUDI AG Laboratory (I/GQ-32).
The restrictions stipulated in VW 60361 shall be observed for mechanical joining elements. The following standards apply to thread dimensions prior to surface treatment: VW11610, VW11614, VW11624, VW11625 and VW11627. For thread dimensions after surface treatment, VW11611 and VW11615 apply.
Avoidance of hazardous substances according to VW 91101.

VW 13750: Issue 2008-06
All-metal clamping nuts shall always be treated with additional or integrated lubricants. Nuts with
non-metallic insert may be treated with lubricant in order to ensure the defined functional character-istics. The lubricant must not be hazardous to the user nor exhibit an unpleasant odor when un-tightening, and shall be suited for automatic tightening. The functional characteristics of nuts trea-ted with protective coating and/or lubricants must not deteriorate within a storage period of six
months in weather-sheltered rooms. The storage temperature shall be between -5 °C and +40°C. Joining elements made of stainless or high-temperature resistant materials may require additional
lubricant treatment in order to comply with the requirements of VW01129.

Vehicle part types
Corrosion load
Resistance class Parts which are not visible in as-installed con-dition, corrosion protection only serves as transit coating and is not compulsory for pro-per functioning.
Low load level. Light protection
grade 1
Interior and exterior components in a pro-tected installation position.
Not for joining elements (for exceptions see VW 01110-1).
Medium load level.

Parts directly exposed to exterior environ-mental conditions (e.g. chassis, engine, transmission).
Parts which are visible in as-installed condi-tion (also from vehicle underside).
Parts which require corrosion protection in order to ensure proper functioning.
Parts such as joining elements which are u-sed in interior as well as exterior areas due to diversity reduction constraints.
Heavy load level.
Heavy protection grade 6
3.2 Drawing specifications
If a certain surface protection is required for the entire part or for several parts in an ASSY, the co-de shall be entered in the "surface protection" title block; e.g. Ofl-t650 (see also VW01058). If sev-eral surface protection types can be applied optionally, the codes of all permissible treatments shall
be given,
e.g. Ofl-r673/x630.
If only partial protection is applied to a part, "see drawing" shall be entered in the "surface protec-tion" title block; the respective area of the part shall be marked by a wide dash-dot line (see Figure
1) and the code shall be specified on a datum line.
If there is only a small area on the part that is without surface protection, the unprotected area shall
be marked (Figure 2). In this case "see drawing" shall be entered in the "surface protection" title block.

VW 13750: Issue 2008-06
If different surface treatments are specified for a given part, "see drawing" shall be entered in the "surface protection" field. The respective areas on the part shall be clearly identified.
If parts from one ASSY are separately coated (one or more different surface treatments), "see dra-wing" shall be entered in the "surface protection" title block of the assembly drawing. The surface treatments 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 parts shall be tested for weldability. Ofl-c340 shall be considered as the standard surface protection type in body assembly (e. g. for weld nuts). 3.4
Agents impairing wetting ability
Lubricants and slushing oils shall be free of silicone oils and other agents that significantly impair wetting ability. 3.5
Friction behavior
The influence of the surface protection on the friction behavior, particularly for parts with metric ISO threads, shall be determined by testing and matched to the performance characteristics (see VDA 235-203). 3.6
Zinc and zinc alloy coatings
Electrodeposited / galvanized coatings are not permissible for high-strength steel and/or standard parts with a tensile strength of R m > 1000 MPA and threaded parts with a property class of ≥ 10.9. Zinc flake coatings according to code letter t shall preferably be used.
Exceptions are possible for parts which are only subject to pressure load, e. g. for bolts according to VW60277 and VW60358 and for nuts with a property class ≤ 10 (nuts with washer assembly only up to ≤ property class 8). For these parts, heat treatment according to DIN EN ISO 4042 is compulsory.
Only in exceptional cases, when electrodeposited zinc coating or zinc alloy coating is absolutely necessary for functional reasons can these coatings be applied with integrated heat treatment ac-cording to DIN 50969 (zinc alloy coatings are preferred). For bolts with metric ISO thread, the use of such coatings is limited to tensile strength values of up to 1200 MPa (see VW60250).
Zinc electroplated or zinc alloy electroplated parts may be post-treated in passivation solutions in order to improve corrosion resistance. Yellowish passivation treatment corresponding to the finish
of yellow chromating treatment with Cr(VI) is not permissible.
Electroplated zinc systems without additional coatings (e. g. paint coatings or sealants) are only
permissible for interior areas.
The appearance of zinc/nickel alloy coatings shall be matched to their immediate environment. Only transparent passivation treatment is permissible for electrically conducting connections.

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, nuts and similar threaded or shaped parts; the next resistance class down is applied to the thread and shank.
柄
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 protection types
Commercial surface protection types can be used for less important applications (e.g. steel wire). However, they are not tested for corrosion resistance. If such protection is sufficient for a given part, only the code of the respective procedure and the figures 010 shall be indicated. The designa-tion for commercial paint coating for example appears as follows: Ofl-x010. It is also possible to distinguish between procedure and finish; e.g. for commercial hot-dip tin coatings: Ofl-g020.
The commercial surface protection types, e.g. Ofl-c010 "commercial zinc coating" and Ofl-r010 "commercial electrodeposited zinc alloy coatings" must not contain any Cr(VI) compounds. Avoidance of hazardous substances according to VW 91101 also applies to commercial surface protection types.
3.9 Parts without surface protection treatment
3.9.1 Joining elements with metric ISO thread
Parts with the designation "plain", surface protection type "without", "-" or without any designation at all shall, as indicated in DIN ISO 8992, be supplied in lightly oiled condition. If, in exceptional cases, unoiled parts must be supplied, this must be indicated in the drawing. To this end, the fol-lowing surface protection types shall be used:
Ofl-a100: corresponds to "not oiled".
Ofl-a101: corresponds to "plain", "without", "-" or without any description in the sense of "lightly oiled" according to DIN ISO 8992.
3.9.2 Other parts
For parts without surface protection and with surface protection specification "without" or "plain, oiled", QP A001 applies. If, in exceptional cases, unoiled parts must be supplied, this must be indi-cated in the drawing by means of the entry “not oiled”. The use of surface protection types intro-duced for joining elements is permissible.

3.10
Assignment of surface protection types and codes
The specifications of Table 2 shall apply. Surface protection types with codes represented in bold italics shall preferably be used for joining elements; surface protection types with framed codes are
standard surface protection types for components without threads.
Surface protection types in brackets contain Cr(VI) and are not available for new designs. Table A.1 specifies which protection types are not permissible for new designs and which protec-tion types shall be used instead. Table A.3 presents the surface protection types according to VW
13750 that correspond to the protection types of VDA 235-104. VW13750, Supplement 1 lists all invalid protection types that were included in earlier issues of VW13750.
