--- Part 2. Chain saw fuel consumption;
--- Part 3. Skidding machinery fuel consumption;
--- Part 4. Cutting area loading machinery fuel consumption;
--- Part 5. Car transport fuel consumption;
--- Part 6. Woodyard production energy consumption.
This part of LY/T 1444 Part 2.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces LY/T 1444.2-2005 "Wood energy consumption in forest production Part 2. Chain saw fuel consumption." This section and
The main changes compared to LY/T 1444.2-2005 are as follows.
--- Modify the scope of the content (see Chapter 1,.2005 edition Chapter 1);
--- Increasing the normative references GB/T 6422, GB 14192 and GB/T 15316 (see Chapter 2);
--- Added definition of correction factor (see 3.6);
--- Increasing the definition of actual fuel consumption for saw logging (see 3.2);
--- Modify the definition of basic fuel consumption for saw logging (see 3.5,.2005 version 2.4);
--- Removed the definition of temperature correction factor (see.2005 version 2.5);
--- Removed the definition of altitude correction factor (see.2005 version 2.6);
--- Removed the definition of forest grade correction factor (see.2005 version 2.7);
--- Remove the definition of tree species correction factor (see.2005 version 2.8);
--- Delete the definition of the coefficient of correction of wood disease rate (see 2.9 of.2005);
--- Remove the logging sawing conditions classification (see.2005 edition of Chapter 3);
--- Modify the sawn timber basic fuel consumption (see Table 1,.2005 edition of Table 1);
--- Increasing the calculation method of the actual fuel consumption of saw logging (see Chapter 5);
--- Increasing the logging fuel logging actual fuel consumption testing methods (see Chapter 6);
--- Added information Appendix B "various energy discount coal coefficient" (see Appendix B).
