Employ three distinct points of sampling situated on a diagonal line of the parallelepiped constituted by the bale and p

33、ositioned at 20 %, 50 % and 80 % of its length. At each point, take one sample of mass at least of 50 g and immediately place it in an airtight bottle, previously tared, to prevent the sample from losing or gaining mass before weighing. 6.3.2 Weighing and determination of dry content of test specime

44、rmative) Examples of application of formulae (1) and (2) A.1 Selling of a lot with specification This consignment is constituted of bales, each comprising groups of packages, different in number (in the practical example, six or seven bags). On the specification the seller shall report: a) the gross

45、 mass for each bale and the number of packages constituting it, and the mass of each package is to be considered as uniform; b) the gross mass of the lot; c) the total tare of the bales (so that the tare of each bale is to be considered as uniform); d) the total tare of the packages (so that the tar

46、e of each package is to be considered as uniform); e) the net mass of the lot. As an example, a specification reported the values shown in Table A.1 (only the values necessary to calculate the commercial mass are listed).

The values representing the sum of th

48、e mean net masses declared and the sum of the dry masses verified, calculated from the Table A.2, are extended to the whole lot and introduced in formula (1) (see 8.1) as follows: X = = 12 843 kg (A.1) 455,233 12 618,43 100 87,03 514,09 Comparing this verified commercial mass with the net mass of th
