19、ederation of national standards bodies (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 co
20、mmittee. International organizations, 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 accord
21、ance with the rules given in the 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
22、 approval by at least 75 % of the 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 11127-1 was prepared by Technical C

28、f a number of parts of ISO 11127 dealing with the sampling and testing of non-metallic abrasives for blast-cleaning.The types of non-metallic abrasive and requirements on each are contained in ISO 11126.The ISO 11126 and ISO 11127 series have been drafted as a coherent set of International Standards
29、 on non-metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex B.This part of ISO 11127 specifies a method for the sampling of non-metallic blast-cleaning abrasives from consignments and for the subdivision of the sample into quantities suitable for undertaking
30、the appropriate test methods specified in other parts of ISO 11127.2 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.2.1total quantityoverall quantity of the abrasive to be tested for which the sampling procedure is to be considered as representative
31、2.2single samplesample obtained from the total quantity by a single sampling operationNOTE This sample is not immediately used for testing.2.3mixed samplesample obtained by mixing a number of single samples2.4reduced samplesample obtained by reduction of a mixed sampleNOTE In order to obtain a sampl
32、e quantity which is suitable for testing, all reduced samples but one are discarded after each reduction; the reduction procedure is then repeated, if necessary, on the sample retained.2.5test samplereduced sample that comprises a mass or volume sufficient for testing, portions of which are immediat

34、ing of inside diameter approximately 25 mm and length approximately 800 mm. The tube shall be pointed at one end and have a “T” handle at the other end. Holes shall be bored in a straight line, lengthways along the tube, and spaced at 50 mm intervals. The diameter of the holes shall be determined by
35、 the size of the particles to be sampled and shall be approximately three times the size of the largest particle.NOTE It is normally sufficient to use holes 10 mm in diameter for non-metallic abrasives.3.2 Sample divider, riffler or other equipment suitable for splitting a sample into parts.4 Proced
36、ure4.1 Sampling of consignmentsDepending on the quantity of abrasive to be tested and the condition of the consignment (packaged or unpackaged), the sampling procedure may be carried out manually or mechanically. Take samples as uniformly distributed as possible over the total quantity of the consig
37、nment, where appropriate, using the sample thief (3.1). The number of single samples to be taken shall be as specified in Table 1.Table 1 Number of single samples to be taken from a consignmentTotal quantitytonnesNumber of single samples100 15Guidance on sampling from stockpiles and transportation u
38、nits is given in Annex A.4.2 Preparation of the mixed samplePour aIl the single samples obtained as described in 4.1 into a suitable container and mix them until a uniform distribution of all particle sizes within the mixed sample can be expected.4.3 Reduction of sample sizeSubdivide the mixed sampl
39、e either mechanically, for example using a riffle-type sample divider (see 3.2), or manually. Unless otherwise specified or agreed, discard one of the reduced samples obtained after each subdivision (see Figure 1). Continue the operation until a test sample of appropriate size is obtained.4.4 Test s
40、ampleThe quantity of test sample needed will depend on the individual test method and is given in the appropriate part of ISO 11127 (see Annex B). Be sure to store the sample in a sealed container until required. Remix the test sample before taking portions for testing to ensure uniformity is mainta
41、ined. Do not remix used portions with remaining sample.ISO 11127-1:2011(E)2 ISO 2011 All rights reservedCopyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-BS EN ISO 11127-1:20115 Sa

46、 sample aggregates that have been stored in stockpiles or loaded into rail cars, barges or trucks. In such cases, the procedure should ensure that segregation does not introduce a serious bias in the results.A.2 Sampling from stockpilesA.2.1 ln sampling material from stockpiles, it is very difficult
47、 to ensure unbiased samples, due to the segregation which often occurs when material is stockpiled, with coarser particles rolling to the outside base of the pile. For coarse or mixed coarse and fine aggregate, every effort should be made to enlist the services of power equipment to develop a separa
48、te, small sampling pile composed of materials drawn from various levels and locations in the main pile, after which several increments may be combined to compose the field sample. If it is necessary to indicate the degree of variability existing within the main pile, separate samples should be drawn from separate areas of the pile.A.2.2 Where power equipment is not available, samples from stockpiles should be made up of at least three increments taken from the top third, at the mid-point and from the bottom third of the volume of the pile.
