This part of GB/T 3452 specifies the basis for judging the appearance quality inspection of O-ring rubber seals for hydraulic and pneumatic applications (hereinafter referred to as O-rings). The standard dimensions of O-rings are specified in GB/T 3452.1; ISO 16031-1 and ISO 16031-2. This part of GB/T 3452 defines and classifies surface defects of O-rings and stipulates the maximum allowable limits for these defects. This part of GB/T 3452 also applies to O-rings used in aerospace engineering.
