上海通用汽车有限公司零部件条形码规范The vehicle components barcode standard of SGM Co. Ltd(1.04 版)1 总则 General Principles1.1 范围：:Area本规范包含的条形码适用于SGM汽车零部件验证系统(VCVS)和可追溯性系统。The barcode included in this standard is valid for all the VCVS(Vehicle Components verification System) and traceability system of SGM.2. 标签Label2.1 条形码Barcode：条形码格式为C39码 或C128码，可数字字母混合。它的数据字符集包含38个字符：0-9，A-Z，- 和空格。(推荐使用128码) The format of barcode is C39 or C128, which can be mix of the numbers and characters . Its media character set includes 38 character:0-9,a-z and space.(Recommendition:C128)2.2 条形码密度和尺寸：Density and Size 条形码的重要参数是窄元素的平均宽度(条形和空格)与宽元素平均宽度的比例，可根据特殊应用要求改变条码高度。除非另有说明，条码最小高度必须为9.5 MM 。用于SGM汽车零部件验证系统(VCVS)和可追溯性系统部件的窄元素平均宽度必须在0.21MM 和0.3MM范围之内，由于工艺能力的允许误差在正负0.025MM.宽窄元素比例必须为3：1，并允许在2.8：1和3.2：1范围内变化.注：根据条形码15位信息格式，最小长度必须为43MM。 The vital parameter of code is the proportion of the average width of narrow element and wide element, which may change the barcode height according to the certain demand. Hence, if no other specify , the lowest height of barcode must be 9.5 MM. All the average width of narrow element available in VCVS and traceability system must fall in the scale between 0.21MM and 0.3 MM. Because the craft ability allows the difference of 0.025 more or less. The proportion of narrow element must be 3 to 1, and allows the variation between 2.8 to 1 and 3.2 to 1.Note: according to the 15 digit information format of barcode, the shortest length must be 43 MM.2.3 可读说明：Readable Description条形码的可读说明必须代表条码编码的字符，必须出现在条形码的正上方或正下方，推荐的可读说明字符是OCR-A，可读说明字符高度不低于2.4MM The readable description of barcode must represent the character of the coding, putting above or below the barcode. The recommended readable description character , the height of which is not lower than 2.4MM or the character is OCR-A.2.4 空白区：Blank Area: 条形码左右两头空白区最少应为6.5MM，上下空白区最少1MM，对于大件部件如前、 后悬架总成，上下空白区最少2MMThe blank area on the right and left side of barcode should at least 6.5MM, the above and the bottom not lower that 1MM. As to those bigger component, for example front or rear suspension, the above and the bottom side of blank area should be at least 2MM.3. 标签材料：label material3.1 标签材料 条形码可以印制在不同的标签材料如纸，聚酯或金属上，对标签材料和相关联的胶水的选择基于应用和工程性能的要求。零部件供应商应根据SGM要求选择标签材料，使得标签固定到最后零件外形上以供扫描时，能满足规范的条件及工程要求。对供应商提供的零部件在SGM总装后标签暴露在外的，应使用聚酯标签材料。要求在零件正常使用中不脱落. Barcode can be printed on different label materials such as paper, polyester or metal surface while the choice of the label material and relative glue is based on the applicable and engineering demand. According to the different demand of SGM, the suppliers need to choose variable label material in order to meet the needs of the standard condition and engineering demand when all the components fixed on the finished components figure are being scanned. If those components barcode provided by the supplier are always explosive outside after installed in SGM, The polyester label material must be used. require not to shed when parts are in normal using.3.2 墨水：ink: 在制作条形码标签时可使用两种墨水，制作条码数据时要求用可读墨水，条形码数据背景必须用不可读墨水。不可读墨水是任一种对条形码扫描设备来说与条形之间的空格一样作用的墨水。可读墨水通常为黑色颜料为基础的墨水，用来打印条形码标签，必须使用不渗透的墨水. When making barcode label, we may choose two kinds of ink; one is readable ink for makingbarcode data and the other is nonreading ink for making background of barcode data. Nonreadable ink is the one having the same effect as the blank one between the barcode when scanned by any barcode scanning equipment. However, readable ink choose the pigment black as the based ink; moreover it must use unseeping ink when printed for code label.4打印标签要求 Requirement of printing label4.1 打印设备print equipment使打印出来的条形码清晰，应使用激光打印机或专用条码打印机，例HP 4000P 激光打印机 ，Zebra 140 XII 条码打印机。 To make the code printed clear, we should use laser printer or professional label printer. Forexample HP 4000P laser printer, Zebra 140 XII label printer.4.2 质量保证要求quality assurance requirement供应商应建立质量保证程序，以保证标签质量和本规范的要求。应包括当SGM零件或图号发生变更时，由断点引起的相应条形码变化，条形码标签批准和修改，条形码标签打印质量检验。 Suppliers should establish the program of quality assurance to ensure the quality of label and requirement of this standard. It includes the approval and amendment of code when SGM component or chart marks alter so as to induce the change of relative barcode because of breakpoint and the quality test when they print barcode label.4.3 打印质量检查要求 Requirement of printing quality check比例符号级别以及给出的尺寸的测量。对打印的条形码检查应该由以下部分组成：检查正确的信息编码，对条形和空格宽度. 供应商每个零件的初始条形码应经SGM采购部和IT部确认.All the code test of printing should compose of the following portions: checking the correct of Information coding, surveying the width of code and blank, the grade of proportion sign and the provided size. Each original barcode of suppliers parts should be authenticated by purchasing team and IT team in SGM. 5条形码信息格式：format of code information5.1 零部件验证 (VCVS)和可追溯性 VCVS and traceability 零部件验证 (VCVS)和可追溯性条形码目的是用来确保正确制造的同时，按特定
