Technical Purpose and Operational Characteristics
This regulatory document defines the metric parameters and design features of knife-edge (sharp-edge) flange connections intended for operation within high-vacuum systems. The standard covers both fixed and rotatable versions mounted via bolted connections.
The technical solutions described in the specification ensure the airtightness of vacuum lines across a wide pressure range: from atmospheric pressure to ultra-high vacuum (10⁻¹¹ Pa). EV Group China supplies components that fully comply with the specified geometric tolerances, ensuring equipment stability under critical loads.
