1. Core Thief Spot Sampling Procedure
Application: This method outlines a tool for sampling liquid / liquid that has a RVP at 101 kPa (14.7 psia) or less in storage tanks, tank cars, tank trucks, boats and floating tanks.
Equipment:
Work principle :
Check / assure a measuring cup and a sample in a clean and dry
Check the liquid level in the tank, use automatic gage or measuring outage measurement, if necessary
Check tool is feasible to operate
Open the bottom cover and adjust the position ropes
Lower the appliance until the desired sample types (see table 5). After reaching the location of sample types, cover the bottom of the appliance by pulling a small part.
Pull back the tool
If the sample contains only half, pour in a sample. If the sample is more than one location, exchange sample into the measuring cup and pour in a sample
Dispose of unwanted residual samples.
Replace the lid on the sample container and attach a label on the sample container.
send container samples to a laboratory or various facilities for mixing and analysis / experiment
2. Bottle / Beaker Spot Sampling
Application:
This sampling procedure is used for sampling liquid (liquid) having RVP 101 kPa (14.7 psia) or sediment present in storage tanks, tank cars, tank trucks, ships and tanks, boats / barges. Solid or semi liquid and even liquids can also be sampled using this procedure, which is equipped with a pure liquid when sampling. For the application of this procedure is often used for sampling examples such as: premium, kerosine, diesel fuel Avgas even.
Equipment:
– Bottle or beaker
– A graduated cylinder and container
– Sampling cage made of metal or plastic that is suitable for placing the container
– Material ballast to sink the container while sampling
– Rope to enter the container
Work principle :
– Check the bottle / beaker sampling, graduated cylinders and containers should be clean
– Make sure the liquid level in the tank estimet
– Tie a rope ballast on the sample bottle
– Insert / Close the cork at the end of the sample bottle / beaker
– Perform sampling a quarter bottle
– Then rinse and dispose of the sample
– Then start doing sampling
– Label the sample container
– Perform taking samples back to a laboratory purposes or for other purposes for mixing or for testing
