I don't really understand what i'm doing

1. Am i suppose to chill a sample to 20c to check?
2. or can i adjust the figure i get by using a table/formula if i know the temperature?
3. if i can do 2, does anybody know where i can get a copyof the formula/table.
4. I'm assuming its the same at 1006?
Sorry for all the questions.
Cheers
Steve
