13、national standards bodies(ISO member bodies). The work of preparing International Standards is normally carried out through ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. Interna

14、tional organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the InternationalElectrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rule

15、s given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational Standard requires approval by at leas

24、or test loads4.1.1 A test load may be a single unit or made up of several components.4.1.2 The components of a test load may be individual units in the form of steel and/or other type (e.g. concrete) blocks; containers filled with water, sand or other granular material with homogeneous density.NOTE

25、A container for containing test loads can be any containment capable of safely bearing the test load (e.g. rubber bagwith water, rigid box with sand, etc.).4.1.3 A container used as a test load should be strong enough to withstand the pressure of the water or other granular filler material; be of a

26、simple (rectangular or cylindrical) shape and shall have marks on interior wall to show the volume ofwater or other granular material to simplify the calculations; have an effective means to drain off the water or remove the filler material after testing.4.2 Equipment for measuring the test load and

27、 accuracy of measurements4.2.1 The equipment for measuring the mass of a test load shall be selected in compliance with nationalspecifications.4.2.2 The number of measurements and the accuracy of measuring the mass of a test load shall be inaccordance with ISO 9373.These requirements shall satisfy b

28、oth the direct and combined methods of measuring the mass of a test load.4.3 Measuring the mass of a test load by the direct method4.3.1 The direct method can be used to measure both the mass of a single load and the total mass of a loadcomposed of several components.4.3.2 The test load to be measur

29、ed shall be placed on a floor scale or lifted to off the floor bya crane equipped with a weight-measuring device. The result of the measurement shall be recorded in thereport.4.4 Determining the mass of a test load by the combined method4.4.1 Determining the mass of a test load as a sum of masses of

30、 its components is recommended for usewhere the test load can be made up of several components with known masses, each of which was measuredby the direct method.In this case, the total mass of the test load shall be calculated as the sum of the masses of the components.4.4.2 Determining the mass of

31、a test load as the sum of the masses of a container and its content isrecommended for use where the test load is a container filled with water, sand or other granular material.The mass of the container shall be measured by the direct method. The mass of the content inside the containershall be weigh

32、ed or calculated as the product of the density of the content by the volume it occupies. Thevolume of the content occupied in the container shall be calculated based on the volume marks. The total massof the test load shall be calculated as the sum of the mass of the empty container and the mass of
