(Naief) #1

In loss on drying procedure ,why should the oven be waited till reaching the desired temperature
i mean cant we put the sample in oven before and leave it then start timing when temperature is 105 for example
(oven which i use has automatic timing )

Loss on drying test is to be performed at specific temperature and for specific time duration or untill you get constant weight. Therefore, if you strat this test while temp of the oven rises to the desired temperature, the duration of test would not be exactly the same as described in the test procedure (monograph).
