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 %. Table 3 Number of verification scale intervals, n = Max/e Accuracy class Verification scale interval, e minimum maximum Minimum capacity, Min (Lower limit) Special (I) 0.001 g ≤ e* 50 000** – 100 e High (II) 0.001 g ≤ e ≤ 0.05 g 0.1 g ≤ e 100 5 000 100 000 100 000 20 e 50 e Medium (III) 0.l g ≤ e ≤ 2 g 5 g ≤ e 100 500 10 000 10 000 20 e 20 e Ordinary (IIII) 5 g ≤ e 100 1 000 10 e * It is not normally feasible to test and verify an instrument to e < 1 mg, due to the uncertainty of the test loads. Table 6 For loads, m, expressed in verification scale intervals, e Maximum permissible errors on initial verification Class I Class II Class III Class IIII ± 0.5 e 0 ≤ m ≤ 50 000 0 ≤ m ≤ 5 000 0 ≤ m ≤ 500 0 ≤ m ≤ 50 ± 1.0 e 50 000 < m ≤ 200 000 5 000 < m ≤ 20 000 500 < m ≤ 2 000 50 < m ≤ 200 ± 1.5 e 200 000 < m 20 000 < m ≤ 100 000 2 000 < m ≤ 10 000 200 < m ≤ 1 000 Note: The absolute value of the maximum permissible error is 0.5 e, 1.0 e or 1.5 e, i.e. it is the value of the maximum permissible error without the positive or negative sign. Note: For multi-interval instruments, refer to 3.3 (including the example).
