Surface preparation by grinding or other method may be necessary where surface irregularities could mask indications of unacceptable discontinuities. 当表面处于毛坯铸件状态时，结果符合要求。当表面的不平整会掩饰不可接受的不连续指示时，表面有必要被打磨或用其他方法处理。 The surface finish of machined areas shall be as indicated on the machining. Ground surfaces shall be no worse than 250rms finish.机械的表面加工区域应该在加工时被标示。毛砂面的加工应该不低于250rms。6.2、Direct Eye Examination直接目视检验Direct visual examination shall be applied and then the examined surface accessed is sufficient to place the eye within 24”(610mm) of surface to be examined and at an angle not less than 30deg. to the surface to be examined.应用直接目视检验时，检验表面的通道应该有足够的空间可目视24”(610mm)内的需检表面，与需检表面的角度不小于30deg。七、结论与报告EVALUATION AND REPORTING7.1、Acceptance Criteria 验收标准Description描述Test Areas检验区域Other Areas其他区域ISO 11971Clsas级别Equivalent相当于SCRATAISO 11971ClsasEquivalentSCRATASurface Texture表面状态4nominal A1,not worse than A25nominal A2,名义上A2not worse than A3不低于A3NonmetallicInclusions非金属杂质1B11B1Gas Porosity气孔2C11C2Metal Removal mechanical s金属切削，工业制品1H11H1Solidification固体Discontinuities不连续NotAccepted认可NotAcceptedNotAcceptedNotAcceptedSand expansion铸砂膨胀Discontinuities不连续NotAccepted不认可NotAcceptedNotAcceptedNotAcceptedMetal inserts金属嵌件NotAcceptedNotAcceptedNotAcceptedNotAcceptedThermal cutSurfaces热切割表面NotAcceptedNotAcceptedNotAcceptedNotAcceptedWelded surfaces焊接表面NotAcceptedNotAcceptedNotAcceptedNotAccepted7.2、Reporting 报告Examination Results shall be recorded using attached forms.检验结果应该使用相关表格记录7.3、Attachment 附件- SCRATA (Steel Castings Research and Trade Association) reference- Reporting FormsSCRATA参考报告表格 目视检测报告 VISUAL EXAMINATION REPORT 报告编号： 检测日期： Report No.: Exam Date：订货人：customer检验申请号码：Request No.公司名称：Project Name产品名：Item Name：参考规格：Reference Code验收标准：Acceptance Standard适用程序：App Procedure图纸号：Dwg.No.制造方法及材质：Processing & Material检查方法：MethodDirect Remote表面条件：Surface ConditionAs casting As machine检查时间：Exam Time 加工前（Before Machining) 加工后（After Machining)表面光照度
