2. Accuracy classes

Directive 2014/31/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to the making available on the market of non-automatic weighing instruments (recast) Text with EEA relevance · European Union

2.1. The following accuracy classes have been defined: I special II high III medium IIII ordinary The specifications of these classes are given in Table 1. Table 1 Accuracy classes Class Verification scale interval (e) Minimum capacity (Min) Number of verification scale intervals n((Max)(e)) minimum value minimum value maximum value I 0,001 g ≤ e 100 e 50000 — II 0,001 g ≤ e ≤ 0,05 g 20 e 100 100000 0,1 g ≤ e 50 e 5000 100000 III 0,1 g ≤ e ≤ 2 g 20 e 100 10000 5 g ≤ e 20 e 500 10000 IIII 5 g ≤ e 10 e 100 1000 The minimum capacity is reduced to 5 e for instruments in classes II and III for determining a conveying tariff. The actual scale interval (d) and the verification scale interval (e) shall be in the form: 1 × 10^(k), 2 × 10^(k), or 5 × 10^(k) mass units, k being any integer or zero. For all instruments other than those with auxiliary indicating devices: d = e. For instruments with auxiliary indicating devices the following conditions apply: e1 10k g; d < e ≤ 10 d. Those conditions do not apply for instruments of class I with d < 10^(–4) g, for which e = 10^(–3) g.
