Common use of For NG Clause in Contracts

For NG. fuelled engines the approval xxxx shall contain a suffix after the national symbol, the purpose of which is to distinguish which range of gases the approval has been granted. This xxxx will be as follows; 4.6.3.1.1. H in case of the engine being approved and calibrated for the H-range of gases; 4.6.3.1.2. L in case of the engine being approved and calibrated for the L-range of gases; 4.6.3.1.3. HL in case of the engine being approved and calibrated for both the H-range and L-range of gases; 4.6.3.1.4. Ht in case of the engine being approved and calibrated for a specific gas composition in the H-range of gases and transformable to another specific gas in the H-range of gases by fine tuning of the engine fuelling; 4.6.3.1.5. Lt in case of the engine being approved and calibrated for a specific gas composition in the L-range of gases and transformable to another specific gas in the L-range of gases after fine tuning of the engine fuelling; 4.6.3.1.6. HLt in the case of the engine being approved and calibrated for a specific gas composition in either the H-range or the L-range of gases and transformable to another specific gas in either the H-range or the L-range of gases by fine tuning of the engine fuelling.

For NG. fuelled engines the approval xxxx mark shall contain a suffix after the national symbol, the purpose of which is to distinguish which range of gases the approval has been granted.

Ht in case of the engine being approved and calibrated for a specific gas composition in the H-range of gases and transformable to another specific gas in the H-range of gases by fine tuning of the engine fuelling; 4.6.3.1.5. Lt in case of the engine being approved and calibrated for a specific gas composition in the L-range of gases and transformable to another specific gas in the L-range of gases after fine tuning of the engine fuelling; 4.6.3.1.6. HLt in the case of the engine being approved and calibrated for a specific gas composition in either the H-range or the L-range of gases and transformable to another specific gas in either the H-range or the L-range of gases by fine tuning of the engine fuelling; 4.6.3.1.7. LNG20 in case of the engine being approved and calibrated for a specific LNG composition resulting in a λ-shift factor not differing by more than 3 per cent the λ-shift factor of the G20 gas specified in Annex 9, and the ethane content of which does not exceed 1.5 per cent; 4.6.3.1.8. LNG in case of the engine being approved and calibrated for any other LNG composition.
