— the declared speed; — the fuel and lubricating oil consumptions under ISO standard conditions. These characteristics declared by the engine manufacturer enable the generating set manufacturer and customer to confirm that the main characteristics of the RIC engines available are suitable for the application. In order to evaluate the generating set service conditions (in particular, sudden-load acceptance) it is necessary to establish the brake mean effective pressure, pme, in kilopascals1), of the engine used, corresponding to the engine power when the generating set is operating at its declared power and rated frequency, and defined as follows: pme = KP / Vstnr where K = 1,2 × 105 for a four-stroke engine and 0,6 × 105 for a two-stroke engine. 5.3 Low-load operationThe customer shall be made aware that extended running under low load may affect the reliability and |
life of the RIC engine. The onus is on the RIC engine manufacturer to provide the generating set manufacturer with data of the minimum load the RIC engine is capable of sustaining indefinitely without deterioration. If the generating set is to be operated at lower loads than this minimum load, the onus is on the RIC engine manufacturer to specify, and if necessary recommend, the measures to be adopted and/or corrective procedures to be used. 6 Speed characteristics6.1 GeneralThe choice of governing system shall be based upon the steady-state and transient speed performance requested by the customer. The generating set manufacturer shall ensure that a suitable governing system, approved by the RIC engine manufacturer, is selected to meet the application requirements. NOTE 1 ISO 3046-4 establishes general requirements and parameters of speed governing systems. ISO 3046-6 establishes general requirements for overspeed protection devices. The terms, symbols and definitions for speed characteristics are given in 6.2 to 6.5. |

NOTES
- Member countries may choose, to be included in their national standards, the sizes which are required to meet their demand.
- For the angles so chosen, only thicknesses which can be rolled in their mills to meet the demand of the users may be selected from the list of thicknesses corresponding to equal angles in table 1.
- The sectional area has been calculated using the formula
S = [l/2 A - l) + 0,214 6 (rroot² - 2rtoe²)] × 1/100
where
S is the sectional area, in square centimetres;
l is the thickness, in millimetres;
rroot is the root radius, in millimetres;
rtoe is the toe radius, in millimetres;
A is the leg length, in millimetres.
- Mass is calculated on the basis of density of steel of 7,85 kg/dm³.
