Schedule 5 (Prescribed Limits of Error)I1
Northern Ireland
I1
(Principle from Clause 2.3 of OIML R51)
The maximum permissible error for any load equal to or greater than the minimum capacity (Min) and equal to or less than the maximum capacity (Max) in automatic operation shall be as specified in Table 1. (Note that the mpe-value includes the digital rounding error of the indicating device.)
Table 1
| Load (m) expressed in verification scale intervals (e) | Maximum permissible error for class Y(y) instruments | ||
|---|---|---|---|
| Class Y(a) | Class Y(b) | Initial verification | In-service |
| 0 <m ≤ 500 | 0 <m ≤50 | ±1.5 e | ±2 e |
| 500 <m ≤ 2,000 | 50 <m ≤ 200 | ±2 e | ±3 e |
| 2,000 <m ≤ 10,000 | 200 <m ≤ 1,000 | ±2.5 e | ±4 e |
(Principle from Clause 2.5.2 of OIML R51)
The maximum permissible error for any load equal to or greater than the minimum capacity (Min) and equal to or less than the maximum capacity (Max) for static weighing in non-automatic operation shall be as specified in Table 2.
Table 2
| Load (m) expressed in verification scale intervals (e) | Maximum permissible error for class Y(y) instruments | ||
|---|---|---|---|
| Class Y(a) | Class Y(b) | Initial verification | In-service |
| 0 <m ≤ 500 | 0 <m ≤ 50 | ±0.5 e | ±1 e |
| 500 <m ≤ 2,000 | 50 <m ≤ 200 | ±1 e | ±2 e |
| 2,000 <m ≤ 10,000 | 200 <m ≤ 1,000 | ±1.5 e | ±3 e |
