Application Summary AI generated
GB/T 14693-2008 specifies the standardized symbols and notation methods for indicating non-destructive testing (NDT) requirements on engineering drawings. It is applied in manufacturing and construction industries, particularly for welding, casting, and forging components, to clearly communicate NDT methods (e.g., ultrasonic, radiographic) and acceptance criteria directly on technical documents. This standard ensures consistent interpretation between design engineers, quality inspectors, and fabrication teams across China.
