United Kingdom

X_{p} = [\frac{(m_{2} - m_{0}) \times m_{1}}{m_{2}} + m - m_{1}] \times \frac{100}{m} = 100 \times (1 - \frac{m_{1} \times m_{0}}{m \times m_{2}})

where:

initial weight, in grammes, of the test sample,

m₁

weight, in grammes, of the test sample after preliminary drying,

m₂

weight, in grammes, of the test sample after crushing or grinding,

m₀
