Abstract：In order to ensure the accuracy of solid biomass carbon hydrogen determination, when we plan to use the electricity weight method to determine the solid biomass carbon hydrogen, its reliability should be verified before use. Aspects such as technological ability of stuff, instruments (standard material) ， sample and reagent, facilities and environment, testing method implement and testing results control were evaluated and confirmed, to ensure the feasibility and adaptability of the new method and the accuracy of results. Repeatability experiments of 10 types solid biomass carbon hydrogen determination were done, the repeatability limit of carbon and hydrogen from calculation was 0.47% and 0.12% respectively, the relative requirements could be met. The electricity weight method and three-furnace method from GB/T 28734-2012 were compared , the accuracy evaluation of electricity weight method was done. There was no bias between determination values of electricity weight method and three-furnace method.
