36、tilled or deionized water, of at least grade 3 purity as defined in ISO 3696.5 ApparatusOrdinary laboratory apparatus and glassware, together with the following:5.1 Pyknometer, Gay-Lussac type, of capacity 50 ml, with a capillary stopper.EN ISO 11127-3:2011 (E) DIN EN ISO 11127-3:2012-04 4 5.2 Oven,

37、 capable of being maintained at a temperature of (110 5) C.5.3 Balance, capable of weighing to an accuracy of 0,01 g.5.4 Desiccator, containing a desiccant such as dried silica gel impregnated with cobalt chloride.6 SamplingTake a representative sample of the product to be tested, as described in IS

38、O 11127-1.7 Procedure7.1 Carry out the determination in duplicate.7.2 Dry a sufficient quantity of the sample by heating it at (110 5) C for 1 h. Allow to cool to room temperature in the desiccator (5.4).7.3 Weigh the clean, dry pyknometer (5.1) to an accuracy of 0,01 g (m1), introduce into it appro

39、ximately 10 g of the dried sample and reweigh (m2).7.4 Add distilled or deionized water (4.1) to the pyknometer until it is completely filled. Replace the stopper and gently shake the pyknometer to displace air adhering to the test portion. Remove the stopper, fill with water and then replace the st

40、opper, forcing excess water out through the capillary tube. Carefully dry the outside of the pyknometer. Ensure there are no air bubbles present. Reweigh the pyknometer and its contents (m3).7.5 Empty the pyknometer of water and test portion, rinsing several times to remove all traces of abrasive. R

41、efill with distilled or deionized water, replace the stopper and ensure there are no air bubbles present. Dry the outside of the pyknometer and weigh (m4).7.6 Care shall be taken that the pyknometer is handled as little as possible in order to prevent warming by hand. Pyknometer, test portion and wa

42、ter shall, as far as possible, be at the same temperature.8 Expression of resultsCalculate the apparent density, A, of the product tested, expressed in kilograms per cubic metre (kg/m3), using the equation A W=( ) ( ) m mm m m m2 14 1 3 2310wherem1is the mass, in grams, of the pyknometer;m2is the ma
