No tank wagons shall be decanted after sun-set other than in exceptional emergent
circumstances. The temperature of the oil should be taken before decanting. While
taking dip measurement, tank wagons should have been allowed to settle for at least
15 minutes before the dip readings are taken and care should be taken to see that the
dip rod touches the bottom of the tank wagons vertically while taking dip
measurement.
8.14 Quality Control:
8.14.1
Sample should be drawn from top and bottom and tested for the
following
properties:-
a. Visible suspended impurities and sludge.
b. Crackle Test: This will indicate a water free sample. Silent but audible crackling
sound indicates traces of water. Vigorous cracking sound indicates appreciable
water.
c. Colour Test: Colour comparison with a 2% solution of potassium bi-carbonate in
water should be made. Samples with dark colour should be further analysed for
gum content according to ASTMD – 381
8.14.2
If the samples drawn reveal no contamination, decanting into the storage tank
should be done.
8.14.3
The following measures should also be adopted for comprehensive quality control:
a. Fuel oil samples from primary fuel oil filter casing should be drawn at least once
in a month and tested for contamination. In case presence of water is detected, the
cause of such contamination should be investigated and water should be drained
out from the loco fuel tank.
b. The ground storage tanks should be drained of water at least once in a week.
c. At least two samples per month from incoming supplies/storage tanks from each
fuelling installation should be tested in detail in the Railway laboratories to ensure
