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) 总则 General Principles 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Label 2.1 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) 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. 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. 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2MM The blank area on the right and left side of barcode should at least 6.5MM, the above and the bottom not lower th
