If the location is not specified, the locations shall be approved by Dell Mechanical Engineer.检验员应按零件图或戴尔公司外观标准6724U中规定的其他适用指定位置的文件，测量L *、a *和b *。

如果文件未指定，则应由戴尔机械工程师批准。

4.2 Gloss (ASTM D523)光泽度(ASTM D523)Gloss specifications will be defined by the Industrial Design team (or its approved agent). Gloss tolerance will be specified in the Dell Color document (example in addendum). Finish gloss shall be determined from the piece part drawing or other applicable documents, and conform to the following spec: Dell Corporate Cosmetic Specification, P/N 6724U, “SPEC,DELL,COSMETIC,CORP-STD”.光泽度规格由工业设计团队(或其认可的代理机构)定义。

戴尔的颜色文件中(如附录)中指定了光泽度公差。

最终光泽度应由零件图纸或其他适用文件确定，并符合以下规格:戴尔公司外观标准，P /N 6724U，“戴尔外观企业标准”。

Applicator shall measure the gloss at the locations specified on the piece-part drawing or other applicable document. If the location is not specified, the locations shall be approved by Dell Mechanical Engineer.检验员应测量在零件图或其他适用文件上注明的光泽度。

如果位置未指定，则位置应由戴尔机械工程师批准。

4.3 Texture or Roughness, (R a, R z, R pc)纹理或粗糙度（Ra,Rz,Rpc）Texture or roughness will be defined by the Industrial Design Team (or its approved agent). Applicator shall measure the texture or roughness at the locations specified on the piece-part drawing. If the location is not specified, the locations shall be approved by Dell Mechanical Engineer. R a, R z, & R pc must all be reported.纹理或粗糙度由工业设计团队(或其认可的代理机构)定义。

检验员应测量在零件图上指定位置的纹理或粗糙度。

如果位置未指定，则应由戴尔机械工程师批准。

Ra,Rz，和Rpc都必须报告。

4.4 Oxide, (ASTM B244), or Dry Film Thickness氧化物(ASTM B244)，或干膜厚度A wide variety of measurement equipment and techniques are available based upon film or finish type. These can include the following:基于膜厚或成品，广泛的测量工具和技术都适用。

如下：1.Cross section2.Scribe3.Tape test (using micrometer)4.Acoustic reflection5.Electromagnetic Conductance6.ProfilometerAny equipment used for thickness measurement shall be calibrated and traceable to NIST (National Institute of Standards and Technology) and comply with ISO (International Organization for Standardization) requirements.用于厚度量测的任何仪器均要可校正和可追溯（国家标准技术局），符合ISO要求。

The master standard plaque and the applicable Dell Color document (examples in addendum) shall define the minimum dry film or oxide thickness in microns to achieve the appearance and performance requirements. It is the finish applicator’s responsibility to ensure that all coatings on the piece part meet the appearance and performance requirements as prescribed in this specification and in the applicable Dell Color Standard document.主标准板和适合的Dell颜色文件（如附件）需用微米级定义最小的膜厚或氧化层厚度。

检验员要确保零件上的所有涂层符合本规范以及适用的戴尔颜色标准文件中规定的外观和性能要求。

Soft touch DFT is to be measured using only cross section or tape method. Other methods are not permitted for soft touch DFT measurement.5.0 Finish Performance Requirements最终性能要求5.1 Adhesion (ASTM D3359)附着力测试（ASTM D3359）For all coatings EXCEPT Conductive Coatings:除了导电涂层以外的所有涂层:Test Parameters: 测试参数:测量参数Curved surfaces or surfaces too small (with one dimension less than 10mm) for Cross-cut – use Method A, “X-cut Tape Test” – Permacell, 3M 250 tape, (or equivalent) shall be used for testing purposes.弯面或太小的表面 (有一尺寸小于10mm)要用交叉切割的方法测试的话，使用方法A，“x – cut胶带测试”- 应使用3M 250胶带 (或同等的胶带)用于测试。

Flat surfaces – where possible, use Method B, “Cross-cut Tape Test,” – Permacell, 3M 250 tape (or equivalent) shall be used for testing purposes.平面-在可行的位置，使用方法B，“交叉切割胶带测试”- 应使用3M 250胶带(或同等的胶带)用于测试。

For DFT < 50 μm, make 1mm spaced cuts. For 50 μm to 125 μm, make 2mm spaced cuts. For DFT > 125 μm, use X-cut method.膜厚< 50 μm，做1毫米空间的切割。
