EN ISO 11127-1:2011 (E) DIN EN ISO 11127-1:2012-04 3 “ 1 ScopeThis is one of a number of parts of ISO 11127 dealing with the sampling and testing of non-metallic abrasives for blast-clean

31、ing.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 on non-metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex B.This part

32、 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 the appropriate test methods specified in other parts of ISO 11127.2 Terms and definitionsFor the purposes of th

33、is 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 representative2.2single samplesample obtained from the total quantity by a single sampling operationNOTE This sample is not im

34、mediately 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 sample quantity which is suitable for testing, all reduced samples but one are discarded after each reduction; the re

35、duction 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 immediately used for testingEN ISO 11127-1:2011 (E) DIN EN ISO 11127-1:2012-04 4 3 Apparatus3.1 Sample thief, made from

36、seamless steel tubing 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 shal

37、l be determined by 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 i

38、nto parts.4 Procedure4.1 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 quan

39、tity of the consignment, 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 an

40、d transportation units 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 sizeSubdivi

41、de the mixed sample 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 o

42、btained.4.4 Test sampleThe 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 un

43、iformity is maintained. Do not remix used portions with remaining sample.EN ISO 11127-1:2011 (E) DIN EN ISO 11127-1:2012-04 5 5 Sample identificationEach sample shall be clearly identified as to its origin. Test samples shall carry at least the following information:a) all details necessary to ident

44、ify the product in accordance with the appropriate part of ISO 11126 (see Annex B), if applicable;b) the consignment identification details, e.g. suppliers name, order number, date of despatch, date of receipt, etc.;c) any product traceability reference which relates to the unit sampled.Total quanti

47、oaded 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 to ensure unbiased samples, due to the segregation which o

48、ften 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 separate, 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 varia
