Testing is to be in accordance with arrangements proposed by the manufacturer and agreed by the classification society. Note: This testing is in addition to that required by 5.1.2(e) and is concerned with the effects of condensation caused by the detection equipment being at a lower temperature than the crankcase atmosphere. Detectors and alarm equipment to be tested. The detectors and alarm equipment selected for the type testing are to be selected from the manufacturer’s normal production line by the classification society witnessing the tests. Two detectors are to be tested. One is to be tested in clean condition and the other in a condition representing the maximum level of lens obscuration specified by the manufacturer. Method The following requirements are to be satisfied at type testing: Oil mist generation is to satisfy Oil mist is to be generated with suitable equipment using an SAE 80 monograde mineral oil or equivalent and supplied to a test chamber having a volume of not less than 1m3. The oil mist produced is to have a maximum droplet size of 5 µm. Note: The oil droplet size is to be checked using the sedimentation method. The oil mist concentrations used are to be ascertained by the gravimetric deterministic method or equivalent. Note: For this test, the gravimetric deterministic method is a process where the difference in weight of a 0.8 µm pore size membrane filter is ascertained from weighing the filter before and after drawing 1 liter of oil mist through the filter from the oil mist test chamber. The oil mist chamber is to be fitted with a recirculating fan. Samples of oil mist are to be taken at regular intervals and the results plotted against the oil mist detector output. The oil mist detector is to be located adjacent to where the oil mist samples are drawn off. The results of a gravimetric analysis are considered invalid and are to be rejected if the resultant calibration curve has an increasing gradient with respect to the oil mist detection reading. This situation occurs when insufficient time has been allowed for the oil mist to become homogeneous. Single results that are more than 10% below the calibration curve are to be rejected. This situation occurs when the integrity of the filter unit has been compromised and not all of the oil is collected on the filter paper. The filters require to be weighed to a precision of 0.1mg and the volume of air/oil mist sampled to 10ml. The testing is to be witnessed by authorised personnel from classification societies where type testing approval is required by a classification society. Oil mist detection equipment is to be tested in the orientation (vertical, horizontal or inclined) in which it is intended to be installed on an engine or gear case as specified by the equipment manufacturer.

What is Oil Mist and Risk from it

Oil Mist Refers to Oil Droplets Suspended in the Air in the Size Range 1~10 μm.

Creation of Oil Mist

Oil Mist may form when High Pressure Fuel Oil, Lubricating Oil, Hydraulic Oil, Or Other Oil is sprayed through a Narrow Crack, Or When Leaked Oil Connects with a High Temperature Surface, Vaporizes, And Comes in Contact with Low Air Temperature.

This Happens While the Fluids Interact with The Moving Parts During Machining.

Smaller Oil Droplets Than Oil Mist is Difficult to Generate Under Normal Circumstances.

Bigger Oil Droplets Than Oil Mist Remain in Spray Form, This has the Advantage of a Higher Ignition Temperature. It Sinks Easily, Reducing Fire Hazard. Oil Mist Inside the Crankcase Can Cause A Bigger Problem.

What is Risk by Oil Mist

When the Concentration of Oil Mist Increases and Reaches the Lower Explosion Limit (LEL; 50 Mg/ℓ, As Defined by the IACS), Explosion May Occur When the Mist Contacts Surfaces of Over 200 °C (392 °F) Or a Spark.

The International Association of Classification Societies (IACS) Mandates That All Ships with A Cylinder Diameter Greater Than 300mm Or Engine Power Over 2,250 kw must be equipped with Either Bearing Temperature Detectors or Oil Mist Detectors.
