Division 4.2 Standard deviation
United Kingdom
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.
