Table 1 Name Symbol marked on instrument Denomination used in this Recommendation Special accuracy I High accuracy II Medium accuracy III Ordinary accuracy IIII * Ovals of any shape, or two horizontal lines joined by two half-circles are permitted. A circle shall not be used because, in conformity with OIML R 34 Accuracy class es of measuring instruments, it is used for the designation of accuracy classes of measuring instruments of which the maximum permissible errors are expressed by a constant relative error in %.
