The residue sh

34、all be not more than 0,2% of total capacity or 100 ml, whichever is the smaller when tested according to either B.3 (procedure A) or B.4 (procedure B). 4.9.2 The residue obtained when the drum is tested according to B.4 (procedure B) is more dependent on the area and condition of the internal surfac

35、e of the drum than procedure A and therefore may be in excess of that for procedure A. NOTE The maximum permitted figure should be agreed between the purchaser and the supplier. 4.10 Finish The external surface finish shall be suitable for the attachment of labels. NOTE 1 The nature of the internal

36、and external finish should be agreed between the purchaser and the supplier. NOTE 2 The preferred colour option for the drum body is blue. The use of any other colour should be agreed between the purchaser and the supplier. 5. Designation A non-removable head (tight head) circular cross-section drum

Principle The capacity is determined by a gravimetric method i.e. by the measurement of the mass of water in the filled drum and its

45、conversion to a capacity. A correction factor can be applied according to Table A.1, but only if the weighing scale used is of a higher precision than the correction. NOTE For plastics drums the water temperature should not exceed 18C. Table A.1 Correction factors a) Water temperature o C Correction

Procedure for determination of total capacity A 3.1 Drill a hole of diameter 5 mm to 10 mm for venting a

47、t the highest point of the closed drum. NOTE The position of the hole depends on the profile of the top. A.3.2 Weigh the empty drum, and record its mass, m 1 ,in grams. A.3.3 Measure the temperature of the tap water to be used to fill the drum. A.3.4 Fill the drum 100 % with water through the normal

48、 filling closure with all other closures fitted and make sure that the air is vented through the drilled hole. NOTE For certain drums, the drum needs to be inclined or tilted, so that the filling hole is at the highest position. A.3.5 Fit and secure the drum closure and remove any surplus water from

49、 the outside. Weigh the filled drum, and record its mass, m 2 , in grams. A.4 Procedure for determination of brimful capacity Follow the same procedure as for the determination of total capacity (see A.3) with the exception that no hole is drilled to vent entrapped air. Fill the drum, with the drum in the normal position for filling, until water overflows at the closure. A.5 Expression of results The difference be
