Larch wood is structurally classified in many countries as one of conifers with the highest load-bearing capacity (strength class of C30). The Spanish visual classification regulation only assigns a strength class to 4 pine woods: Laricio pine (Pinus nigra Arn. var. Salzmannii), Silvestre pine (Pinus sylvestris L.), Radiata pine (Pinus radiata D. Don), and Pinaster pine (Pinus pinaster Ait.). This work adds to the number of structurally characterised species by creating a visual classification table for Japanese larch wood (Larix kaempferi (Lamb.) Carr.) which differentiates between 2 visual classes, MEG-1 and MEG-2. Characteristic strength values were calculated for each class (f_k,MEG-1 = 31.80 MPa, f_k,MEG-2 = 24.55 MPa), mean module of elasticity (E_0,mean,MEG-1 = 13,082 MPA, E_0,mean,MEG-2 = 12,320 MPA) and density (ρ_k,MEG-1 = 456.6 kg m⁻³, ρ_k,MEG-2 = 469.1 kg m⁻³), before finally assigning a strength class of C30 to visual class MEG-1, and a strength class of C24 to visual class MEG-2.

在许多国家/地区，落叶松木材在结构上均属于具有最高承重能力的针叶树之一（强度等级为C30）。西班牙视觉分类监管只有一个强度等级分配给4倍的松林：Laricio松树（松属黑。阿恩变种Salzmannii），Silvestre的松树（欧洲赤松L.），辐射松（辐射松D.唐），海岸松和松（Pinus pinaster Ait。）。这项工作通过为日本落叶松木材（Larix kaempferi（Lamb。）Carr。）创建视觉分类表来增加结构特征物种的数量，该分类表区分了两种视觉分类，MEG-1和MEG-2。计算每个类别的特征强度值（f _k，MEG-1  = 31.80 MPa，f _k，MEG-2  = 24.55 MPa），平均弹性模量（E _{0，平均值，MEG-1}  = 13,082 MPA，E _{0，平均值，MEG-2}  = 12,320 MPA）和密度（ρ _K，MEG-1  =456.6公斤米^-3，ρ _K，MEG-2  =469.1公斤米^-3），最后才分配强度等级C30的视觉类MEG-1，和一个强度等级的C24为视觉类MEG-2。
