根据现行的中华人民共和国国家标准GB4814-84原木材积表、GB4815-84杉原条材积表、GB449-84锯材材积表推算得出的，供各部门的木材经销、木材检量等人员用于迅速查定各类木材的累计材积数。 一、查定方法（1）单根的或不满10根的原木、原条、特等锯材和普通锯材的材积累计数，可直接从本手册中分别查得。（2）根数为10根、20根、30根的整十位数的原木、原条、特等锯材和普通锯材的材积累计数，可先相应查出1根、2根、3根的材积数，然后将小数点右移一位（即扩大10倍）得到。（3）10根以上且带有个位数根数的原木、原条、特等锯材和普通锯材的材积累计数，可先得出整十位数根数的材积数，然后再加上直接查得的个位数根数的材积数而得。 二、对GB4814-84原木材积表的说明1、GB4814-84原木材积表的规定本标准适用于所有树种的原木材积计算。（1）检尺径自4-12cm的小径原木材积由下式确定： V=0.7854L(D+0.45L+0.2)10000 式中：V材积(m)； L检尺长(m)； D检尺径(cm)。（2）检尺径自14cm以上的原木材积由下式确定： V=0.7854LD+0.5L+0.005L+0.000125L(14-l)(D-10)10000（3）原木的检尺长、检尺径按GB144.2-84原木检验 尺寸检量的规定检量。（4）检尺径4-6cm的原木材积数字保留四位小数，检尺径自8cm以上的原木材积数字，保留三位小数。2、GB4814-84原木材积表中的附录（圆材材积计算公式）的规定（1）检尺长超出原木材积表所列范围而又不符合原条标准的特殊用途圆材，其材积按下式计算： V=0.8L(D+0.5L)10000（2）圆材的检尺长、检尺径按GB144.2-84原木检验 尺寸检量的规定检量。 检尺径，按2cm进级；检尺长的进级范围及长级公差允许范围由供需双方商定。（3）缺陷限度及分级标准由供需双方商定。（4）地方煤矿用的坑木材积按下表计算： 检 尺 径(cm)检 尺 长(m)1.41.61.8材 积(m)80.0080.0100.011100.0130.0150.017
