For oil gas analysis, one litre fo oil is required. * For a PCB test, at least 50 ml of oil is required. Tap-off point for oil gas analysis: normally top of tank Tap-off point for other tests: normally bottom of tank 1. Use clean 1-litre bottles with gas-tight closure to hold the sample. 2. Spezial aluminium bottles with plastic screw caps are generally used. The sample bottles must close so tightly that no air can be drawn in during cooling. 3. If glass bottles ar used, the oil sample should not be drawn off unless you are sure that the temperature of the sample is higher than or equal to the storage or dispatch temperature.If Bild 1: not, please consult the test laboratory. Ölprobenentnahme mit Ölprobeflasche und Ölauffanggefäß 4. Samples for gas analysis should always be taken using the overflow method. The operations described under 5 and 7 below should be carried out quickly and without interruption so as to 1 Trafokessel prevent the sample from coming into contact with the atmosphere as far as possible. 2 Ölprobehahn 3 Schlauch 5. Method of drawing oil from the oil sample tap 4 Ölprobeflasche Screw onto the tap o coupling element with seal, hose fitting and oilproff hose (30 to 50 cm 5 Ölauffanggefäß long) turn the tap on and fill the outer vessel with 2 to 3 lires of oil (from the outlet pipe).Insert the hose in the bottle so that ist end is just short of the bottom of the bottle. Turn the tap on and fill the bottle from the bottom upwards, slowly at first and then quickliy until two or three times the content of the bottle have overflowed into the outer vessel. Finally, reduce the flow from the tapand, with oil still flowing, pull the bottle downwards off the hose. Seal the bottle immediately. 6. Method of drawing oil from the drainage device A22/31/40 DIN 42 551; this method is not suitable for gas analysis. Put the outer vessel (5) under the oil outlet. Use an openendet spanner to unscrew the cap (contains some oil) Carefully unscrew the square-headed inner plug screw (6.2) until oil starts toflow from the outlet (6.3). Rinse the bottle with some oil. Srew the caß (6.1) back on by hand to stop the oil flow. Fill the bottle (4) almost full by opening the caß (6.1) again. Seal the bottle (4) and label it. 7. The method of drawing oil from the drainage device A22/32/40 DIN 42 551 with the aid of a length of hose is analogous to that described under 5 above, the drainage device being operated as described under 6 above. 8. Dispose the oil in the outer vessel in the proper way.
