在国际专利分类（IPC）系统中，一个指定的大类、小类、大组或小组代码通常代表了一整套相关的技术主题，并且涵盖了该分类下的所有子分类。因此，如果绿色清单指定了C10L作为小类的代码，则它不仅包括C10L本身的内容，也包括了其下所有的大组和小组（如C10L 5/00, C10L 9/00等）的所有内容。

同样的逻辑适用于更具体的分类。例如，如果指定的是C10L 5/40这样的大组代码，则它不仅代表了这一特定的大组，同时也涵盖了其下所有小组的专利（如C10L 5/40-5/48）。所以，当绿色清单中出现如“C10L 5/40, 9/00”或者“C10L 5/40-C10L 5/48”这样的表述时，这意味着所有从C10L 5/40到C10L 5/48范围内的专利都被认定为绿色专利。

简而言之，IPC代码的指定是分级和递进的。一个更宽泛的分类（如小类或大组）的指定意味着包括了其下所有的子分类中的专利。希望这能解答你的疑惑！

我觉得不包含，因为里面有这个F16H48不止到48/30        F16H 3/00-3/78, 48/00-48/30

Therefore, the IPC entries listed in the IPC Green Inventory should be used as indicative information, i.e. by searching for the IPC symbols listed in the IPC Green Inventory next to the subject matters in the hierarchical structure, you may find Green-related technologies in the search results. However, by using only IPC symbols for search, you may also get some “noise” in your search results as well. As in the example you referred to, “Biogas” and “IGCC”  in general can be found in the IPC under main group C10L 3/00 entitled “Gaseous fuels; Natural gas; Synthetic natural gas obtained by processes not covered by subclasses C10G, C10K; Liquefied petroleum gas”, which is indicative and should not be understood that all patent information classified under this maim and its subgroups are all, e.g. “Biogas-related”. Keywords together with IPC symbols (e.g. subgroups under C10L 3/00, such as C10L 3/02, C10L 3/04) depending on your search requirements or your interested subject matter should always be used, in order to limit the number of your search results.
