ISO 17314:2008规定了一种计算手动便携式森林机械可回收率和可回收率的方法，每种回收率均以机器的质量百分比（质量分数百分比）表示。 当机器最初投放市场时，机器制造商可以进行计算。它不包括液体。

ISO 17314:2008 specifies a method for calculating the recyclability rate and the recoverability rate of manually portable forest machinery, with each rate being expressed as a percentage by mass (mass fraction in percent) of the machine. The calculation can be performed by the machine manufacturer when a machine is initially put on the market. It does not include fluids.
