24、:2011(E)Preparation of steel substrates before application of paints and related products Test methods for non-metallic blast-cleaning abrasives Part 1:Sampling1 ScopeThis is one of a number of parts of ISO 11127 dealing with the sampling and testing of non-metallic abrasives for blast-cleaning.The
25、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 of ISO
26、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 this docum
27、ent, 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 immediatel
28、y 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 reduction
29、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 testing ISO 2011 All rights reserved 1BS EN ISO 11127-1:20113 Apparatus3.1 Sample thief, made from seamless
30、 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 shall be det
31、ermined 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 into part
32、s.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 quantity of
33、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 and transp
34、ortation 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 sizeSubdivide the m
35、ixed 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 obtained.
36、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 uniformity
37、 is maintained. Do not remix used portions with remaining sample.ISO 11127-1:2011(E)2 ISO 2011 All rights reservedBS EN ISO 11127-1:20115 Sample identificationEach sample shall be clearly identified as to its origin. Test samples shall carry at least the following information:a) all details necessar
38、y to identify 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.To

41、een 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 to ensure unbiased samples, d
42、ue 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 separate, small sampling pile compos
43、ed 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 pi
44、le.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. A board pushed vertically into the pile just above the sampling point aids in preven
45、ting further segregation. In sampling stockpiles of fine aggregate, the outer layer, which might have become segregated, should be removed and the sample taken from the material beneath. Sampling tubes of diameter at least approximately 30 mm and length at least approximately 2 m may be inserted int
46、o the pile at random locations to extract a minimum of five increments of material to form the sample.A.3 Sampling from transportation unitsIn sampling coarse aggregates from railroad cars or barges, an effort should be made to enlist the services of power equipment capable of exposing the material
47、at various levels and random locations. Where power equipment is not available, a common procedure requires excavation of three or more trenches across the unit at points that will, from visual appearance, give a reasonable estimate of the characteristics of the load. The trench bottom should be app
48、roximately level, and at least 0,3 m in width and in depth below the surface. A minimum of three increments from approximately equally spaced points along each trench should be taken by pushing a shovel downward into the material. Coarse aggregate in trucks should be sampled in essentially the same
49、manner as for railroad cars or barges, except for adjusting the number of increments according to the size of the truck. For fine aggregate in transportation units, sampling tubes as described in Clause A.2 may be used to extract an appropriate number of increments to form the sample.1) Abstracted from ASTM D75-1987, Standard Practices for Sampling Aggregates.ISO 11127-1:2011(E)4 ISO 2011 All rights reservedBS EN ISO 11127-1:2011Annex B (informative) International Standards for non-metallic blast-cleaning abrasivesRequiremen
