CHAPTER IIU.K. Automatic Catchweighers
1. Accuracy Classes U.K.
1.1.Instruments are divided into primary categories designated by:U.K.
X or Y
as specified by the manufacturer.
1.2.These primary categories are further divided into four accuracy classes:U.K.
XI, XII, XIII & XIIII
and
Y(I), Y(II), Y(a) & Y(b)
which shall be specified by the manufacturer.
2. Category X Instruments U.K.
2.1.Category X applies to instruments used to check prepackages made up in accordance with the requirements of Council Directive 76/211/EEC of 20 January 1976 on the approximation of the laws of the Member States relating to the making-up by weight or by volume of certain prepackaged products() applicable to prepackages.U.K.
2.2.The accuracy classes are supplemented by a factor (x) that quantifies the maximum permissible standard deviation as specified in point 4.2.U.K.
The manufacturer shall specify the factor (x), where (x) shall be ≤ 2 and in the form 1 × 10k, 2 × 10k or 5 × 10k, where k is a negative whole number or zero.
3. Category Y Instruments U.K.
Category Y applies to all other automatic catchweighers.
4. MPE U.K.
4.1. Mean error Category X/MPE Category Y instruments U.K.

XI | Y(I) | XII | Y(II) | XIII | Y(a) | XIIII | Y(b) | X | Y |
---|
0 < m ≤ 50 000 | 0 < m ≤ 5 000 | 0 < m ≤ 500 | 0 < m ≤ 50 | ± 0,5 e | ± 1 e |
50 000 < m ≤ 200 000 | 5 000 < m ≤ 20 000 | 500 < m ≤ 2 000 | 50 < m ≤ 200 | ± 1,0 e | ± 1,5 e |
200 000 < m | 20 000 < m ≤ 100 000 | 2 000 < m ≤ 10 000 | 200 < m ≤ 1 000 | ± 1,5 e | ± 2 e |
4.2. Standard deviation U.K.
Maximum permissible value for the standard deviation of a class X (x) instrument is the result of the multiplication of the factor (x) by the value in Table 2 below.
Table 2
Net Load (m) | Maximum permissible standard deviation for class X(1) |
---|
m ≤ 50 g | 0,48 % |
50 g < m ≤ 100 g | 0,24 g |
100 g < m ≤ 200 g | 0,24 % |
200 g < m ≤ 300 g | 0,48 g |
300 g < m ≤ 500 g | 0,16 % |
500 g < m ≤ 1 000 g | 0,8 g |
1 000 g < m ≤ 10 000 g | 0,08 % |
10 000 g < m ≤ 15 000 g | 8 g |
15 000 g < m | 0,053 % |
For class XI and XII (x) shall be less than 1.
For class XIII (x) shall be not greater than 1.
For class XIIII (x) shall be greater than 1.
4.3. Verification scale interval — single interval instruments U.K.

XIII | Y(a) | 0,1 g ≤ e ≤ 2 g | 100 | 10 000 |
5 g ≤ e | 500 | 10 000 |
XIIII | Y(b) | 5 g ≤ e | 100 | 1 000 |

Where:
r

total number of partial ranges
5. Measurement Range U.K.
In specifying the measurement range for class Y instruments the manufacturer shall take account that the minimum capacity shall not be less than:
class Y(I) | : | 100 e |
class Y(II) | : | 20 e for 0,001 g ≤ e ≤ 0,05 g, and 50 e for 0,1 g ≤ e |
class Y(a) | : | 20 e |
class Y(b) | : | 10 e |
Scales used for grading, e.g. postal scales and garbage weighers | : | 5 e |
6. Dynamic Setting U.K.
6.1.The dynamic setting facility shall operate within a load range specified by the manufacturer.U.K.
6.2.When fitted, a dynamic setting facility that compensates for the dynamic effects of the load in motion shall be inhibited from operating outside the load range, and shall be capable of being secured.U.K.
7. Performance Under Influence Factors And Electromagnetic Disturbances U.K.
7.1.The MPEs due to influence factors are:U.K.
7.1.1.For category X instruments:U.K.
