***零件供应商负责本技术要求在检具(测量支架)规划、设计、、验收中的贯彻。

4. 规定4.1 检具（测量支架）的概述4.1.1检具（测量支架）的定义检具是一种用来测量。

在零件生产现场, 通过检具实现对零件的在线检测,为此需要将零件准确地安装于检具上, 然后通过目测,或测量表,或卡尺对零件型面, ,也可以借对零件上不同性质的孔及零件与零件之间的联接位置进行目检，从而保证在试生产及起步生产时实现零件质量状态的快速判断。

在此情况下，通过目检或测量可以判断: 零件轮廓大小CAD/CAM直接。

对于零件上的某些极其重要的，还能利用检具进行数值检测。

通常不能借检具直接获得零件基于车身坐标系统精确的坐标值, 而是将零件置于检具上通过三坐标测量机测量方才获得。

现代检具的结构在设计时同时考虑其可以作为测量支架使用。

但是当检具的在线检查，应首先满足检具的在线检查。

1999.03激光焊—铝平点焊、质量保证1、总则1.1、范围阐述了激光铝平点焊中不规则的评价标准。

此标准适用于厚度为0.8毫米到5毫米原材料。

评价的是生产的质量而不是性能。

性能必须通过合适的冲击实验、耐力实验和功能实验来做出客观的评价。

实验需由有资格的人员在有必要装备的实验室来完成。

1.2、要求的有效性如果标准在图纸中做出陈述，要求应适合所有的焊缝。

在个别情况下，图纸规定了违背条款，这些条款具备优先权。

2、评价焊缝必须符合所列的评价标准。

对于每300毫米的焊缝，在三个位置取样，要求至少每10毫米一次。

在焊缝的起点/终点不少于10毫米处进行焊接情况的评定。

同样适用于未提及的焊缝。

实际的实验计划优于所规定的说明。

3、测试3.1外部特性根据表一，通过可视测试。

3.2内部特性根据表二，通过底层截面来评定。

如有疑义，根据3.2测试的特性可适用于依据3.1测试的特性换言之以3.2测试的特性为标准。

tl226大众标准及检测方法

tl226大众标准及检测方法嘿，咱今儿就来聊聊 tl226 大众标准及检测方法。

这可真是个重要的玩意儿呢！你想啊，这就好比是给一件东西定个规矩，得符合这个标准才行。

就像咱盖房子，那总得有个标准吧，不能这儿歪一点，那儿斜一点的。

tl226 大众标准呢，就是给相关产品或者流程设定的这么个框框。

那这个标准都包括啥呢？哎呀，那可多了去了。

比如说尺寸得多大呀，质量得达到啥水平呀，性能得咋样呀，反正就是各种方面的要求。

这可不是随便定的，那都是经过好多专家研究、讨论，还有实践得出来的呢！那检测方法呢，这就是来看看是不是真的符合标准啦。

就跟咱考试似的，得有个办法来判断你到底考得好不好。

检测方法有很多种呢，有的可能是用仪器测一测，有的可能是靠人眼瞧一瞧，还有的可能得做些实验啥的。

比如说，要检测一个零件是不是符合 tl226 标准，可能就得用专门的测量工具，量量尺寸对不对呀，看看表面有没有啥瑕疵呀。

这就好像挑水果，咱得看看有没有坏的地方，个头够不够大。

要是检测一个流程呢，可能就得盯着看每一步是不是都按要求做了，有没有偷工减料啥的。

这标准和检测方法可重要了呀！要是没有它们，那不乱套了嘛。

产品质量参差不齐，那咱用起来能放心吗？肯定不行呀！所以说呀，这tl226 大众标准及检测方法就是保障我们能用上好东西的重要手段呢。

你说，要是都不按标准来，那做出来的东西都没法用，这不浪费资源嘛。

就好比做衣服，尺寸都不对，那能穿吗？这不是白瞎功夫嘛。

而且检测方法也得靠谱呀，不然怎么知道到底合不合格呢。

咱平常买东西的时候，其实也能看到一些标准的影子呢。

那些质量好的东西，不就是因为符合了各种标准嘛。

所以呀，可别小看了这tl226 大众标准及检测方法，它们在我们生活中可起着大作用呢！总之呢，这 tl226 大众标准就是个框框，检测方法就是个工具，它们一起保证了产品和流程的质量。

咱得重视它们，这样才能让我们的生活更加美好，更加有保障呀！你说是不是呢？。

For sealing elements on gas-carrying systems such as the air-conditioning system, these coatings are also unsuitable, as the surface contains microcracks.Components coated like this must not be plastically deformed by flaring, pinching, bending etc. Approval of first supply and changes according to VW 011 55.Avoidance of hazardous substances acc. to VW 911 01.Page 3TL 244: 2002-0510 finished parts are required for complete testing.The type of zinc/nickel coating process to be used (electrolyte) is subject to agreement with the VW Group Central Laboratory (K-QS-32) and/or the AUDI Group Test Laboratory (I/GQ-32) prior to usage.Unless certain sections of parts 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 class and display the prescribed properties. The coating shall have firm adherence to the base material. Before coating, threaded parts shall exhibit a tolerance zone position corresponding to the coating thickness, metric threaded parts preferably according to VW 116 24. After the coating process, the h-zone must not be exceeded and the H-zone must not be fallen below.The layout and control of the production process shall not impair the functional characteristics of the finished part.The protective coatings must exhibit no pores, cracks, damage or other flaws that impair the corrosion protection and/or specified appearance.Given proper mounting, the coating shall not be damaged if this would lead to impairment of function and/or decrease of the specified corrosion protection.The surface treatment method shall be conducted so that damage by delayed hydrogen-induced brittle fractures can be ruled out. Verification by tension testing according to DIN 50 969.3.3 Joining elementsIn the case of screws and quick fastening elements the test specifications listed below only apply to the head and/or the wrench bearing surfaces, in the case of nuts they apply only to the face surfaces and/or wrench bearing surfaces. For threaded and similar molded parts such as studs the test requirements only apply to the face surfaces.The reduced requirements according to section 3.11 apply to process-determined weak coating areas on joining elements such as shank and thread.Furthermore, the specifications in DIN EN ISO 4042 concerning the maximum possible thickness of the electroplated coating in the threaded profile shall be taken into consideration.These reduced requirements also apply to quick fastening elements.Joining elements with metric threads shall be treated with lubricants according to TL 521 32 in order to ensure constant coefficients of friction. The coefficients of friction are tested according to VW 011 29.For further information see VW 011 10, section 2.3.4 Zinc/nickel coating processFor components with geometrically complicated shapes the coatings deposited from alkaline systems are especially suitable. Their outstanding feature is a more favorable throwing power (metal distribution). This results in a uniform nickel insertion rate over the total current range. Should a direct deposition as on casting materials, for example, be only possible under poor conditions, a surface activation by deposition of a pre-zinc coating from a weakly acidic zinc or zinc alloy electrolyte is permissible. The use of a weakly acidic Zn/Ni electrolyte must be agreed upon by the VW Group Central Laboratory (K-QS-32) and/or the AUDI Group Test Laboratory (I/GQ-32).Page 4TL 244: 2002-053.5 Cr(VI)-free conversion layersIn order to improve the corrosion resistance of electrolytically deposited zinc/nickel coatings to salt water and condensed water, a post-treatment in passivation solutions is technical standard.The passivation treatment solution must not contain any Cr(VI) compounds in order to ensure that the resultant conversion layers are likewise Cr(VI)-free.3.6 Post-treatmentsAs especially in those areas visible for the customer the outer appearance of the parts must not be impaired by strong color variations or iridescence, a sealing post-treatment of the conversion layer can be performed. This results also in an improvement of the corrosion protection. The layer structure may become thicker by 0.5 µm to 2 µm, but the functionality of the surface must not be impaired.If besides the corrosion protection further functional surface characteristics such as paintability, compatibility with other agents, sliding properties, threadening behavior, vulcanizability, temperature behavior or conductivity are required, part-specific tests or functional tests shall be performed.The post-treatments must not cause any impairments such as unsightly drop-like residues resulting from cristallization and/or formation of a film on the part surface.3.7 Base materialSee drawing.3.8 Nickel contentTesting according to PV 1214 and/or PV 1216 (only for first-sample test).X-ray fluorescence method testing using measurement devices based on DIN EN ISO 3497. Requirement: 12 % to 15 %In exceptional cases a nickel content of 10 % to 15 % is permissible, if the coatings are deposited from weakly acidic electrolyte systems. This is subject to agreement of the VW Group Central Laboratory (K-QS-32) and/or the AUDI Group Test Laboratory (I/GQ-32), and must be specified on the drawing.3.9 Electroplated coating thicknessesTesting according to DIN EN ISO 1463, DIN EN ISO 2178 and DIN EN ISO 3497 (see section 4). Requirement: 8 µm up to 25 µm (for general-type components),8 µm up to 15 µm (for threaded parts, measuring point according to DIN EN ISO4042).3.10 Adhesive strengthThermal shock test based on DIN EN ISO 2819.The specimen part is aged for 30 minutes at (300 ± 10) °C and then dipped in water at a temperature of 15 °C to 25 °C.Requirement: no large-scale or bubble-shaped stripping of the zinc coating.Page 5TL 244: 2002-053.11 Corrosion behaviorThe corrosion resistance of the systems must be ensured in the as-received condition and also after a 24-hour period of heat aging at 120 °C. These are minimum requirements and must always be adhered to.Testing according to DIN 50 021-SS; evaluation according to DIN EN 12 329.The test durations and requirements according to table 3 apply to the evaluation of the passivation treatment layers and to their sealing.The following applies to the evaluation of the zinc/nickel coatings, their passivation treatment layers and sealing:-No base metal corrosion after a test duration of 720 h for all surface protection classes according to TL 244;-no zinc corrosion after the test durations specified in table 3.The following applies to the evaluation of the shank and thread areas of threaded and quick fastening elements:-No base metal corrosion after a test duration of 480 h.Table 3 – Test durations and requirements for passivation treatment layer and sealingevaluationTest duration in hSurfaceprotectionclass Barrel-galvanizedgoods aRack-galvanizedgoodsRequirementOfl-r642, r672Ofl-r645, r677120240 Ofl-r643, r673240240No zinc corrosion after the prescribed test duration, minor optical changes ("gray cast") permissiblea Barrel galvanized goods are small parts which cannot be coated as rack galvanized goodsbecause of their shape, and which therefore are coated as bulk goods.NOTE: For specific components lower requirements may be permitted: For example, only 120 h resistance to zinc corrosion applies to casting surfaces on the brake caliper.4 Note on testing for measurement of coating thicknessA coating thickness measurement device based on the X-ray fluorescence measuring procedure according to DIN EN ISO 3497 (e.g. Fischerscope device of Helmut Fischer GmbH & Co., Germany) which allows a measurement of the coating thickness and the nickel content at the same time shall be used.Choose measuring duration so that repeat accuracy is lower than or equal to 0.5 weight percent nickel. Repeat accuracy is defined as the standard deviation of measuring values under repeat conditions (same observer, same equipment, same specimen with same measuring point, short intervals between measurements).Measurement of coating thickness is performed by means of the magnetic/inductive method according to DIN EN ISO 2178 applying a probe. For specimens with a rough surface, several individual measurements (at least 5) shall be performed on the reference surface. The measuring result indicates the local coating thickness. The measuring equipment shall be tested by comparative testing at regular intervals or prior to a measurement series.Page 6TL 244: 2002-055 Referenced standards1PV 1214Zinc / Nickel Alloy Coatings; Determination of the Nickel ContentPV 1216Zinc / Nickel Alloy Coatings; Determination of the Nickel Content Using ICP-OESTL 521 32Lubricant for Threads; Material RequirementsVW 011 10Joining, Heavy Duty Threaded Joints, Design Engineering and Process AssuranceVW 011 29Limit Values for Coefficients of Friction; Mechanical Joining Elements with Metric ISO ThreadVW 011 55Vehicle Supply Parts - General, Approval of First Supply and ChangesVW 116 24Metric ISO Thread; Limit Dimensions for 6G/6f Tolerance ZoneVW 137 50Surface Protection of Metal Parts; Surface Protection Classes, Codes, RequirementsVW 911 01Environmental Standard for Vehicles, Vehicle Parts, Materials, Fuels, Avoidance of Hazardous SubstancesDIN 50 021Spray Tests with Different Sodium Chloride SolutionsDIN 50 969Resistance of High-Strength Structural Steel Components against Hydrogen-Induced Brittle FractureDIN EN 12 329Electrodeposited Coatings of Zinc with Supplementary Treatment on Iron and SteelDIN EN ISO 1463Metallic and Oxide Coatings – Measurement of Coating Thickness;Microscopical MethodDIN EN ISO 2178Non-Magnetic Coatings on Magnetic Substrates – Measurement of Coating Thickness – Magnetic MethodDIN EN ISO 2819Metallic Coatings on Metallic Substrates – Electrodeposited and Chemically Deposited Coatings – Review of Methods Available for Testing Adhesion DIN EN ISO 3497Metallic Coatings – Measurement of Coating Thickness – X-Ray Spectrometric MethodsDIN EN ISO 4042Fasteners – Electroplated Coatings1 In this section terminological inconsistencies may occur as the original titles are used.。
