14、odies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizati
15、ons, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the
16、 ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of t
17、he member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8007-3 was prepared by Technical Committee ISO/TC 47, Chemistry,

Sidewall blocks used in the production of aluminium have specific requirements for sampling and, while the statistical basis for sampling given in ISO 5022 can be applied, further or modified requirements apply. ISO 3951 describes sampling plans for
21、 inspection by acceptance quality limit (AQL). ISO 2859-0 and ISO 2859-1 describe sampling plans for inspection by attributes.

27、59-1, with the additional requirements given in 5.2 and 5.3 and Clauses 6 to 8. Sidewall blocks are usually unsuitable for their original purpose after samples have been taken. The sampling plan shall recognize that the block may have to be declared scrap if it cannot be reworked for a different pur
28、pose. 5.2 Sampling The sampling positions shall take into consideration the size and shape of different sidewall blocks. It is strongly recommended that an agreement be made between the supplier and the user concerning sampling locations. Samples shall, wherever practicable, be taken parallel and pe
29、rpendicular to the major axis of the block. Manufacturers of sidewall blocks, formed by extrusion or vibration, have knowledge of the predominant grain direction for which it is recommended to take samples in parallel and perpendicular directions. Manufacturers are recommended to inform users of the
30、 predominant grain direction where appropriate. Users are recommended to request this information from manufacturers or suppliers. If the predominant grain direction is not known then, samples shall be taken in orthogonal x, y and z directions. A sketch of the positions and direction of sampling sha
31、ll be included in the sampling report see 8 e). 6 Dimensions of the sample(s) The dimensions of the sample(s) shall be chosen according to the tests to be carried out. The minimum dimension (usually the diameter) shall be three times the maximum particle size of the dry aggregate, where this is know
32、n. Reference shall be made to the International Standards relating to the test(s) to be carried out to ensure that the sample(s) taken from the sidewall block are of suitable dimensions. The samples taken from the sidewall block may already be of the correct dimensions. If not, then the dimensions o
33、f the core-drilled sample(s) shall also allow for the provision of parallel sides when the finished test piece is prepared. The cross-section of the finished test sample(s) taken from the sidewall block shall be circular. The dimensions of the test sample(s) shall be given in the sampling report see
34、 8 f). The specific dimensions of the piece(s) to be tested are normally given in the appropriate International Standard. Where the International Standard does not specify the dimensions of the test piece(s), a diameter of 30 mm or 50 mm is recommended for practical purposes. The length of the test
35、piece should be at least 1,5 times the diameter. 7 Procedure The sample is to be taken by core drilling or by sawing from suitable locations and in directions parallel and perpendicular to the predominant grain direction, if known. Sampling in the x, y and z directions is strongly recommended. BSISO
