    55gal oil drum sample techniques

    Hey, trying to figure where you guys are pulling oil samples to proof test the drum contents?

    Thinking it is 1/3 or 2/3 down, but shouldn't be on the bottom?

    Thanks,

    If we are talking typical mineral oil you'd want to take it from the bottom or near the bottom of the barrel or vessel, any possible moisture or contaminants would be near the bottom displaced by the oil.

    Paul Gill book chapter 4, page 211 states:

    Sampling oil from Drums or shipping containers

    Drum should remain undisturbed for several hours before drawing the sample. A glass or Pyrex thief is recommended for sampling because it can be easily inspected for cleanliness. A glass tube approximately 36" long, 1" on diameter and tapered at both ends is recommended.

    Discard first thief of oil.

    Draw the sample in the following manner:
    With the top end covered with the thumb, lower the tube to within approximately 1/8" from the bottom of the drum.

    Additional information can be found here. It discusses the specific gravity of oils/reason to sample from the bottom.
