O-形密封圈的 O 应用连字符连接；b). “ISO3601-1”应用连字符连接；c). 相应表中的尺寸代码（见表 1 到表 6）以及内径公差级的“A” 和 “B”应用连字号连接。d).标称内径和截面直径，应用一个“”和连字号连接。e).等级字母（N, S 或 CS）按ISO 3601-3 标准执行。 例 1. O-形密封圈-ISO3601-1-011A，651.75-S 例 2. O-形密封圈-ISO3601-1-125B-32.992.62-N7.2 符合ISO 3601 标准本部分的航空工业应用的O-形密封圈应标注如下：a） 单词“O-形密封圈”的 O 应用连字符连接；b） “ISO3601-1”应连接一个大写字母“A” (标注为航空工业应用)并连接一个连字符；c） 从相应表中选出的规格代码 （参照表7到表11），然后连接一个连字符。d） 标称内径和截面尺寸，分别用一个“”并接一个连字符；e） 等级字母 （N,S 或 CS） 应按ISO 3601-3 标准执行。例 1. O-形密封圈-ISO3601-1A-C0545-54.53.55-S例 2. 0-形密封圈-ISO3601-1A-D1250-1255.3-CS.8. 验收检验用检测方法 在用户验收时如需要按ISO 3601标准的本部分检验O-形密封圈的话，其检验程序应在买卖双方签订购货合同时进行协商。附录B就这种检验程序提供了一些检验方法上的可行性资料。9. 识别编码表 （参照ISO 3601 标准的本部分）制造厂强烈推荐在选用符合ISO 3601 标准的本部分时，应在试验报告，产品目录和销售文件中使用下列说明：“O-形密封圈内径，横截面直径，公差和尺寸识别编码符合ISO 3601-1：2008 标准有关流体动力系统-O-形密封圈-第一部分： 内径，横截面直径，公差和尺寸识别编码的标准。38 / 38表 1 规格代码，规格，内径及A，B 级内径公差，一般工业用O-形密封圈- 截面直径，d
