This standard replaces LY/T 1287-1998 "Energy-saving monitoring method for wood-based panel hot press". The main changes of this standard compared with LY/T 1287-1998 "Electrical Panel Hot Press Energy Saving Monitoring Method" are as follows. --- Increased the scope of application of energy-saving monitoring of wood-based panel hot presses (see Chapter 1); --- Increased energy-saving monitoring and inspection items for wood-based panel hot presses (see 3.1); --- Added heat transfer oil testing standards GB 265 and GB 268 (see Chapter 2); --- Added wood-based panel hot press inspection project (see 3.1); ---Modified the normal working conditions of energy-saving monitoring of wood-based panel hot press (see 4.1); --- Revised the inspection scope of the energy-saving monitoring sealing condition of the wood-based panel hot press (see 4.2); --- Increased inspection of the heat transfer oil index of wood-based panel hot press (see 4.6); --- Increase the ratio of the coverage area of the carbonized layer on the inner wall of the heat transfer oil pipe of the wood-based panel hot press pressure plate to the total area of the inner wall (see 4.7); --- Increased the qualified indicators for energy-saving monitoring of wood-based panel hot presses (see 5.4, 5.5); ---Modified the thermal efficiency value of the production of plywood by wood-based panel hot press (see Table 1); ---Modified the thermal efficiency value of the production of particleboard by wood-based panel hot press (see Table 1); --- Revised the thermal efficiency value of the dry production of fiberboard by wood-based panel hot press (see Table 1); ---Modified the thermal efficiency value of the fiberboard production of the wood-based panel hot press (see Table 1); --- Modified the surface temperature of the steam main pipe insulation layer (see 5.6); --- Added monitoring items in the energy-saving monitoring report of wood-based panel hot press (see Appendix C). This standard was proposed by the State Forestry Administration.
