1 Scope This part of GB/T 3452 specifies the housing dimension and tolerance of O-shaped rubber sealing ring (hereinafter referred to as O-ring) for general hydraulic and pneumatic applications. This part of GB/T 3452 is applicable to the O-rings specified in GB/T 3452.1-2005 Fluid power systems - O-rings - Part 1: Inside diameters, cross-sections, tolerances and size identification code. If the working pressure exceeds 10 MPa, the structural type with anti-extrusion ring shall be adopted. Note: The housing dimension of O-ring for special application shall be determined by the manufacturer and the user of O-ring through negotiation. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of GB/T 3452. For dated references, subsequent amendments (excluding corrections), or revisions, of any of these publications do not apply to this part of GB/T 3452. However parties to agreements based on this part of GB/T 3452 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
