How to take an Oil Sample Extended Version

Oil samples are filled into Inspec sample kits and are sent to Oilcheck for testing and analysis.

The samples kits are purchased on a pre-paid basis and are sent with a Sample Description Sheet.

It is important that the sample is taken correctly to provide a representative analysis of all of the oil contained in an equipment compartment. The sample will not be accurate if the oil is allowed to cool and settle as this will cause the heavier contaminates to drop to the bottom of the compartment.

The sampling procedure is explained in each sample kit (shown below).

Standard sampling pump and tube. Method Derived from AS 4002.2-2001
Preparation	Equipment components need to be at the correct operating temperature for a consistent mix of oil. The sampling technique is crucial to the sample results and to monitor the wear trends of the compartment.
	Consider extracting the sample from a centralised area where the fluid is in motion and away from inactive areas caused by corners and baffles.
	Preventative maintenance of compartments is where a correct sample technique is very important. Poor sample technique may result in the potential to misrepresent wear or contamination which may lead to undiagnosed failure. It is important you follow the steps and advice and don't rush.
Taking the Sample	Once a selecting a suitable area of the reservoir from which the sample is to be extracted, clean the area around the entry point before breaking into the reservoir.
	Insert the sampling tubing into the desired area of the reservoir. Ensure the tubing is in a flowing oil stream in the reservoir. A dead spot or corner will give you a false result. Also, take note of how far the tube goes into the reservoir. Try to sample in the same local area each time - this will maintain consistency in your sample results. Using the sampling pump as a vacuum source, draw 20-30ml (¼ of a bottle of sample) into the sample bottle.
	Remove the bottle from the pump and replace the lid. Shake and discard the 30 ml of oil - this will remove any impurities that may be present in the bottle or tubing. Empty discarded sample into a waste oil container.
	Remember to discard oil & hoses in an environmentally friendly manner.
	Reattach the sample bottle to the pump this time drawing 100ml (¾ of a bottle) or to the fill line, maintaining the same sampling position in the reservoir.
	Detach the sample bottle from the pump and immediately place the red stopper and lid directly onto the bottle.
	Note: The red stopper on the bottle is to prevent leakage during transit (WA & NT disregard this step).
	Place bottle in the zip lock plastic bag and then into black mailing canister.
Documentation & Sample Description Sheets	Peel off the second sample number sticker provided on the bottom of the form and stick onto the lid of the bottle to ensure that documentation is tracked to the sample.
	Peel off the "customer to retain" sample number sticker to retain with your records. Use this number to identify and track your sample.
	A hard copy of the report will be mailed to the address on the sample description form.
	Email versions of the report are available at no cost. Just tick the sample description sheet to select the report format you would like to receive. The PDF format is an identical replica of the printed hardcopy report.
Despatch	Place the completed form and the sealed plastic bag containing the numbered sample bottle into the black mailing canister.
	Despatch by the means available.
	If the test results are required urgently, please include an email address so we can notify you immediately after the analysis has been completed.
	A hard copy of the report will be mailed to the address on the front of this form. As well as a hard copy you may also stipulate to have the report emailed in PDF format as stipulated above.
