For oil sampling to be effective there are several fundamental principles that must be adhered to:
- The sample must be a true representative sample of the oil in the compartment.
- The oil must be agitated to ensure that particles are suspended throughout the oil.
- The sample must be taken from the same point or depth in the compartment each time.
- Circulation systems should be sampled on the return line or after the pump prior to filtration.
- All efforts should be taken to ensure that the sampling process does not introduce further contaminants to the reservoir.
- All efforts must be made to ensure the sample it self is not contaminated.
Correctly installed Sampling Points ensure that:
- The sample is taken from the same point each time.
- The oil is extracted from the same depth in the compartment each time.
- Dirt and other contaminants are kept clear of the entry point of the sample tube.
- Contamination associated with dipstick removal is reduced.
- Sampling occurs quickly and easily.
- Correct installation of Sampling Points in a location that facilitates ready access to lubrication reservoirs enhances operational efficiencies and improves occupational health and safety protocols.
