14、(normative) Capacity measurement method for plastics jerricans A.l Principle The capacity is determined by a gravimetric method, .e. by the measurement of the mass of water in the filled jerrican and its conversion to a capacity. A correction factor can be applied according to Table A.l but only if
15、the weighing scale used is of a higher precision than the correction. NOTE For plastics jerricans the water temperature should not exceed 18 OC. Table A.l - Correction factors a) Water temperature Correction factor (F) OC 12 1,000 5 14 1,000 8 16 1,001 1 18 1,001 4 a) See 4.1.1 of EN IS0 90-2:1999.
16、A.2 Apparatus A.2.1 Weighing scale, with an accuracy of at least 0,l % of the weight being measured. A.3 Procedure for determination of total capacity A.3.1 Drill a hole of diameter 5 mm to 10 mm for venting at the highest point of the closed jerrican. NOTE The position of the hole depends on the pr
17、ofile of the top. A.3.2 Weigh the empty jerrican, and record its mass, ml, in grams. A.3.3 Measure the temperature of the tap water to be used to fill the jerrican. A.3.4 Fill the jerrican 100 % with water through the normal filling closure with all other closures fitted and make sure that all the a
18、ir is vented through the drilled hole. NOTE For certain jerricans, the jerrican needs to be inclined or tilted so that the filling hole is at the highest position. A.3.5 Fit and secure the jerrican closure and remove any surplus water from the outside. A.3.6 Weigh the filled jerrican and record its
19、mass, m2, in grams.

20、air. Fill the jerrican, with the jerrican in the normal position for filling, until water overflows at the closure. AS Expression of results The difference between the mass of the filled jerrican, m2, and the mass of the empty jerrican, ml, (m2 - ml), if necessary multiplied by the correction factor
21、 (6, represents the capacity of the jerrican as determined by the procedure used.

22、bility are obtained by determining the mass of water left as a residue in the jerrican after drainage under gravity. 8.2 Apparatus 8.2.1 Weighing scale, with an accuracy of at least 12 g. B.3 Determination of drainability using the top section of the jerrican (procedure A) B.3.1 Cut the top off the
23、jerrican. B.3.2 Retain the top section and fit the appropriate closure(s). B.3.3 Weigh the top section with closure(s) fitted and record its mass, ml, in grams. 6.3.4 Position the top section, top down, on a test rig so that it is held at the angle specified by the manufacturer (preferably O“ to 20“
24、) with the designated closure opening at its lowest position. 8.3.5 Fill the top section with approximately I O I of tap water. 8.3.6 Wait until the water surface has settled and then open the closure. B.3.7 Allow the water to drain for 5 min without moving or shaking the top section and refit the c
25、losure. B.3.8 Re-weigh the top section, still in the top down position and record its mass, m2, in grams. 8.4 Determination of drainability using a complete jerrican (procedure B) 8.4.1 Weigh the empty jerrican including its closure(s) and record its mass, ml, in grams. 8.4.2 Fill the jerrican with
26、a limited quantity of tap water, approximately 1 O I. Close the jerrican. B.4.3 Rotate the jerrican to ensure a wetting of all inner surfaces. 8.4.4 Open the jerrican and place it in a horizontal position with the designated closure opening in its lowest position and leave until the liquid flow stop
27、s (position I as shown in Figure B.l). O BSI 05-2000 Page 13 EN 1271 2:2000 6.4.5 Slowly incline the jerrican up to the manufacturers recommended angle which ensures the optimal draining (preferably O“ to 20“) and leave the jerrican in this position for 5 min (position 2 as shown in Figure B.I), wit
28、hout moving or shaking the jerrican. 8.4.6 Fit and secure the designated closure and remove any surplus water from the outside. 8.4.7 Weigh the emptied jerrican, and record its mass, m2, in grams. c 1 position 1 2 position 2 3 designated closure FIGURE B.l - Determination of drainability B.5 Express
29、ion of results The difference between the mass of the emptied jerrican, m2, and the mass of the empty jerkan, ml, (m2 - m,), represents the residue in the jerrican and is termed the absolute drainability of the jerrican. The relative drainability of a jerrican is obtained by expressing the absolute
30、drainability as a percentage of the total capacity.
