本文件规定了真空技术中使用的非刀口法兰和套环的尺寸。 这些尺寸确保了螺栓法兰、夹紧法兰和旋转法兰之间的互换性: a） 组件是同质的（例如，螺栓法兰或夹紧法兰）还是异质的（例如，螺栓法兰通过螺栓或夹具或螺栓和旋转法兰与夹紧法兰组装）。 b） 与法兰一起使用的密封圈是弹性体O形圈还是金属密封圈，前提是它们与附录A中给出的线性密封载荷兼容。交叉参考:ISO 3669:2017ISO 1127ISO 3ISO 4200ISO 887ISO 273ISO 286-1ISO 2861购买本文件时提供的所有当前修订版均包括在内。

This document specifies the dimensions of non-knife-edge flanges and collars used in vacuum technology. The dimensions ensure interchangeability between bolted, clamped and rotatable flanges: a) whether the assembly be homogeneous (for example, bolted flanges or clamped flanges) or heterogeneous (for example, bolted flanges assembled with clamped flanges either by means of bolts or clamps or by means of bolts and rotatable flanges). b) whether the sealing rings used with the flanges be elastomer O-rings or metal sealing rings, provided that they are compatible with the linear sealing loads given in Annex A.Cross References:ISO 3669:2017ISO 1127ISO 3ISO 4200ISO 887ISO 273ISO 286-1ISO 2861All current amendments available at time of purchase are included with the purchase of this document.
