Let stand until box and sample are at room temperature, then weigh accurately* . Place the box In a ventilated oven maintained at 100*C* i 1* for 6 hours* Remove, cool in desiccator to room temperature and accurately reweigh* From the loss in weight calculate the evapor ation in percent* Report't,o second decimal place only* v :-V ....... *1 ' '[ .V .
