PARAFINE WAX/OIL CONTENT

Parafine Content is obtained according to the following
procedurers:

 1. Pick up the specified quantity of Carbon Rods, and
    Mark numbers (1,2,3..n) on each test piece.  Measure
    weight (W) of each down to four decimals in grams.

 2. Heat the test pieces on Steel Net with Gas Burner
    until the Parafine WAX/OIL is burnt out completely.
    In doing this, be sure not to oxidize the test pieces
    by red-heating.

 3. Cool the test pieces and measure weight (W1) of each
    test piece.

 4. Calculate the Parafine WAX/OIL Content according to
    the following formula:

                                      W - W1
     PARAFINE WAX/OIL Content(%) =  ---------- x 100
                                        W
