Directive 2014/32/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 measuring instruments (recast) (Text with EEA relevance) (c. 32)

ANNEX VII U.K.

SPECIFIC REQUIREMENTS U.K.

2. Accuracy classification and maximum permissible errors (MPEs) U.K.

2.6. Conversion devices U.K.

MPEs on converted indications due to a conversion device are equal to ± (A — B), A and B being the values specified in Table 2.

Parts of conversion devices that can be tested separately

(a) Calculator U.K.

MPEs on quantities of liquid indications applicable to calculation, positive or negative, are equal to one-tenth of the MPEs as defined in line A of Table 2.

(b) Associated measuring instruments U.K.

Associated measuring instruments shall have an accuracy at least as good as the values in Table 4:

Table 4

MPE on Measurements	Accuracy classes of the measuring system
	0,3	0,5	1,0	1,5	2,5
Temperature	± 0,3 °C	± 0,5 °C			± 1,0 °C
Pressure	Less than 1 MPa: ± 50 kPa From 1 to 4 MPa: ± 5 % Over 4 MPa: ± 200 kPa
Density	± 1 kg/m3		± 2 kg/m3		± 5 kg/m3

These values apply to the indication of the characteristic quantities of the liquid displayed by the conversion device.

(c) Accuracy for calculating function U.K.

The MPE for the calculation of each characteristic quantity of the liquid, positive or negative, is equal to two fifths of the value fixed in (b).
