  "text": "Classification\n3.1. Instruments with one weighing range Instruments equipped with an auxiliary indicating device shall belong to class I or class II. For these instruments the minimum capacity lower limits for these two classes are obtained from Table 1 by replacement in column 3 of the verification scale interval (e) by the actual scale interval (d).\nIf d < 10−4g, the maximum capacity of class I may be less than 50 000 e.\n3.2. Instruments with multiple weighing ranges\nMultiple weighing ranges are permitted, provided they are clearly indicated on the instrument. Each individual weighing range is classified according to 3.1. If the weighing ranges fall into different accuracy classes the instrument shall comply with the severest of the requirements that apply for the accurcy classes in which the weighing ranges fall.\n3.3. Multi-interval instruments\n3.3.1. Instruments with one weighing range may have several partial weighing ranges (multi-interval instruments).\nMulti-interval instruments shall not be equipped with an auxiliary indicating device.\n3.3.2. Each partial weighing range i of multi-interval instruments is defined by:\nits verification scale interval ei with e(i + l) ≥ ei\nits maximum capacity Maxi with Maxi = Max\nits minimum capacity Mini with Mini= Max (i − l) and Mini= Min\nwhere:\ni = 1, 2, . . . r,\ni = partial weighing range number,\nr = the total number of partial weighing ranges.\nAll capacities are capacities of net load, irrespective of the value of any tare used.\n3.3.3. The partial weighing ranges are classified according to Table 2. All partial weighing ranges shall fall into the same accuracy class, this class being the instrument’s accuracy class.\nTable 2\nMulti-interval instruments\nI = 1, 2,…rI = partial weighing range numberR = total number of partial weighing ranges\nMinimum capacity (Min)\nNumber of verification scale intervals\nClass\nVerification scale interval (e)\nMinimum value\nMinimum value\nn=Maxie(i+1)\nMaximum value\nn=Maxiei\n(1) For i = r the corresponding column of Table 1 applies, with e replaced by er.\nI\n0,001 g ≤ei\n100 ei\n50 000\n—\nII\n0,001 g ≤ei ≤0,05 g\n20 ei\n5 000\n100 000\n0,1 g ≤ei\n50 ei\n5 000\n100 000\nIII\n0,1 g ≤ei\n20 ei\n500\n10 000\nIIII\n5 g ≤ei\n10 ei\n50\n1 000",
