Terminology Oil Sampling

Some of the terms involved in this method are:
1. Sample:
a section taken / transferred from a total volume which may or may not contain constituents (constituents) in the same parts that exist in the total volume.
2. Representative Sample:
a section taken / transferred from a total volume containing constituents (constituents) in the same parts that exist in the total volume.
3. Spot Sample:

the samples taken at specific locations in a tank or from a pipe flow at any given time.
4. Sampling:
all steps necessary to obtain a representative sample (representative) of a pipe, tank or other vessel, and moving the sample in a container which can represent the test sample was taken for analysis.
5. Test Spicemen:
a representative sample (representative), taken from the primer or intermediate container sample, to be analyzed.
6. Surface sample:
spot samples scooped from the surface of the liquid in the tank.
7. Top Sample:
spot sample obtained 15 cm (6 in) below the top surface of the liquid.
8. Upper Sample:
spot sample taken from the middle 1/3 of the top of the tank contents (within 1/6 the depth of the liquid below the surface of the liquid).
9. Middle Sample:
spot sample taken from the middle of the tank contents (within 1/2 the depth of the liquid below the surface of the liquid).
10.Lower Sample:

spot sample taken from the middle 1/3 of the bottom of the tank contents (within 5/6 the depth of the liquid below the surface of the liquid).
11.Bottom Sample:
spot sample collected from the material at the bottom of the tank, container or pipe flow at the lowest point. note: – the terminology of the bottom sample varies greatly. – Recommended location to establish with certainty (eg 15 cm from the bottom of the tank).
12.Outlet Sample
Spot samples taken from the bottom of the tank to the outlet tank to the type of fixed or floating tanks.
13.Clearence Sample
Spot samples taken 10 cm (4 in) below the pit exit pipe (tank outlet)
14.Drain Sample
Sample obtained from “water draw-off valve” in storage tanks Note: Sometimes the same sample with a bottom drain sample to the case on the tank car

15.All-level Sample:
an example of which was obtained by inserting a beaker or cap bottles to a point as close as possible to “draw-off level”, then open the lid and raise it at a speed such that an estimated 3/4 filled when exiting from the liquid.
16.Running Sample:

sample obtained by lowering the beaker or bottle to the limit of the base “outlet connection” or “swing arm” and raise them back to the top of the oil at the same speed so that the beaker or bottle filled approximately 3/4 when removed from oil
17.Composite Sample:
a combination of spot samples mixed in a volume ratio of spot sample material which has been obtained.
18.Tank Composite Sample
The combined made of upper, middle and lower samples from a single tank.
19.Multiple Tank Composite Sample:
a mix of individual sample or composite sample has been obtained from some vessel tanks or compartments containing material with the same grade.
20.Boring Sample:
examples of the material contained in a barrel, box, bag or rod / beam obtained with the punch material with a drill.
21.Dipper Sample:
an example of which is obtained by placing a “dipper” or collecting container in the crevice of a stream to collect a number of definite volume at fixed time intervals for a constant flow rate or at variable time intervals are proportional to the flow rate.
22.Grab Sample:
an example of which is obtained by collecting the same quantity of parts of a solid delivery
23.Grease Sample:
an example of which is obtained by scooping / rake or “dipping” a quantity of soft materials or semi-liquid contained in the packs in a representative manner.
24.Tube Sample:
sample obtained with a sampling tube or a particular decision, either as a “core sample” or “spot sample” of a particular point in a tank or container.
