15、 for indirect characterisation of resistance to microbes on the part of cables, wires and flexible cords. Note: With rising ether content and falling ester content in polyurethane, resistance to microbes increases. A.2.3.2 Definition A.2.3.2.1 Saponification value The quantity of potassium hydroxide

16、, expressed in mg, and required for the saponification of lg of the sample being examined.

19、s specified in this standard to the contrary. A.2.3.5 Preparation From the test specimen a sample shall be taken, which is sufficient for at least two tests. A. 2.3.6 Procedure Using the accurate laboratory balance approximately 0,5 g of finely granulated material are weighed into the 250 ml flask w

20、ith ground-in stopper to the nearest 0,001 g (quantity 8. After addition of 50 ml of Tetrahydrofuran, the flask is sealed with the ground-in stopper and placed in the heating cabinet at a temperature of 6OoC until the sample has completely dissolved. Shaking of the flask from time to time can speed

21、up the dissolving process. Then 25 ml of caustic potash solution shall be added from a burette along with some boiling stones. The sample is saponified for 3 hours in the water bath under reflux and at boiling temperature. Immediately afterwards and without cooling, after addition of 50 ml of distil

22、led water and three drops of phenolphthalein solution, back titration is performed with hydrochloric acid (consumption a). A blank test shall be carried out in the same way (consumption 6). The test shalt be carried out on at least two samples. A.2.3.7 Evaluation of test results The saponification v

23、alue of mg KOH/g shall be calculated according to the following numerical equation: (b-) 28,05 E saponification value = Wherein: a = consumption in ml of hydrochloric acid solution c(HCI) = 0,5 mol/l in titration of the sample 6 = consumption in ml of hydrochloric acid solution c(HCI) = 0,5 mol/l in
