United Kingdom
The value of Sλ of the resulting blend of pipeline gas and admixture gas shall be within the range specified in Table 9.1 for the specified reference fuel.
Table 9.1
Required range of Sλ for each reference fuel
| The engine shall not be required to be tested on a gas blend with a Methane Number (MN) less than 70. In the case that the required range of Sλ for GR would result in an MN less than 70 the value of Sλ for GR may be adjusted as necessary until a value of MN no less than 70 is attained. | ||
| Reference fuel | Minimum Sλ | Maximum Sλ |
|---|---|---|
| GR f1 | 0,87 | 0,95 |
| G20 | 0,97 | 1,03 |
| G23 | 1,05 | 1,10 |
