1、木材检尺标准木材尺寸统一由厘米、米、立方米公制量度单位计算。l=J l= = i直径：原木量小头直径，除去皮厚，以2厘米为增进单位，不足者四舍五入。长度：原木长25米的按0.2米进位，长5. 5米以上的按0.5米进位；直径检量：以小头断面的去皮直径，经进舍后作为检尺径。均以2厘米为 一增进单位，满1厘米进位，不足1厘米时舍去。例如检量的直径为24. 8厘米, 则检尺径为24厘米。原木检尺径的量取是通过小头断面中心，先量短径，再通 过短径的中心垂直量长径。如短径不足26厘米，其长短径之差在2厘米以上， 或短径自26厘米以上，其长短径之差自4厘米以上者，称为椭圆材，均以长短 径的平均值进舍后作为检

2、尺径，否则均以短径为准。对小头端面呈不规整、双心、 劈裂等现象的原木，则按有关规定予以量取。长度检量：长度应在大小头两端面之间相距最短处取直检量。除加工用原 木允许2. 5米这一长级以及特级原木外，其他原木的长度增进单位均为0. 2米， 不足0.2米的舍去。此外，还规定各类原木有一定的长级公差。例如直接使用原 木、针叶树加工用原木和阔叶树加工用原木的长级公差均为-2+6厘米，特级原 木为06厘米。如量得的实际长度小于原木标准规定的长级而又不超过负偏差 时，则仍按标准的长级计算，否则按下一级的长度计算。二、原木材积计算标准续我检尺长m粒尺径，cm5.05.25.4S.65.8材积m 3621.7
