26、 The types of metallic abrasive and requirements on each are contained in the various parts of ISO 11124. The ISO 11124 and ISO 11125 series have been drafted as a coherent set of International Standards on metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex
27、A. This part of ISO 11125 specifies a method for the sampling of 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 11125. 2 Definitions For the purposes of th
28、is part of ISO 11125, the following definitions apply. 2.1 total quantity the overall quantity of the abrasive to be tested (for example the quantity of a consignment) for which the sampling procedure is to be considered as representative 2.2 sample unit the packaged unit of sale, e.g. pallet, drum,
29、 bulk sack, from which single samples (see 2.3) are taken 2.3 single sample a sample obtained from the total quantity by a single sampling operation. This sample is not immediately used for testing 2.4 mixed sample a sample obtained by mixing a number of single samples 2.5 reduced sample a sample ob
30、tained by reduction of a mixed sample NOTE 1In order to obtain a sample 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. 2.6 test sample a sample that comprises a mass
31、 or volume sufficient for testing, portions of which are immediately used for testing 3 Apparatus 3.1 Sample thief, made from 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. Hol
32、es 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 the size of the particles to be sampled and shall be approximately three times the size of the largest particle. NOTE 2It is usually sufficient to use hole
33、s 10 mm in diameter for metallic abrasives. 3.2 Sample divider, riffler or other equipment suitable for splitting a sample into parts. 4 Procedure 4.1 General The sampling procedure is designed to obtain samples which can be considered representative of the consignment or total quantity under examin
34、ation. The sampling procedures specified in Table 1 assume that little or no variation in properties takes place within a single sample unit. Metallic abrasives are susceptible to segregation of particle size during handling and transit from manufacturer to point of final use. Such segregation is mi
35、nimal however and, where the packaging is in the form of bags on a palletized unit, single samples may be considered representative of sample units. Where the sample unit is in the form of drums, bulk sacks, etc., segregation may become significant. For these sample units more than one single sample
36、 shall be taken. NOTE 3Schematic diagrams for sampling and subdivision of samples are given in Figure 1 and Figure 2. 4.2 Number of sample units The number of sample units (pallets, drums, bulk sacks, etc.) to be sampled in a consignment shall be as specified in Table 1. Samples from different sampl
37、e units shall not be mixed together. Table 1 Number of units to be sampled Total quantity of the consignment tonnes Number of units to be sampled 11 2 to 52 6 to 103 11 to 255 255 per 25 units Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 19 09:00:52 GMT+00:00 2006, Uncontrolled Copy, (c) BSI
38、EN ISO 11125-1:1997 4 BSI 04-2000 4.3 Sampling of sample units 4.3.1 Pallets made up of bags, boxes, etc. Take a single sample of approximately 500 g from one bag, box, etc., on the pallet. This forms the test sample for that pallet (see Figure 1). 4.3.2 Drums, bulk sacks or similar Use the sample t
39、hief (3.1) to obtain three single samples from different areas of the sample unit. Mix the single samples together in a suitable container until a uniform distribution of all particle sizes can be expected. This forms the mixed sample (see Figure 2). NOTE 1The scheme shown is based on a total quanti
40、ty of 10 tonnes. NOTE 2Single samples are taken from one bag, box, etc., selected at random from each pallet.

Subdivide mixed samples from other sample un
42、its mechanically, using a sample divider (3.2). Discard all but one of the reduced samples. Continue the operation until a test sample of approximately 500 g is obtained. 4.5 Test sample A test sample of approximately 500 g will provide sufficient test material to carry out all the test procedures i
43、n ISO 11125, parts 2 to 7 (see Annex A). 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 maintained. Do not remix used portions with remaining test sample. 5 Sample identification Each sample shall be
44、clearly identified as to its origin. Test samples shall carry at least the following information: a) all details necessary to identify the product in accordance with the appropriate part of ISO 11124 (see Annex A), if applicable; b) the consignment identification details, e.g. suppliers name, order
45、number, date of despatch/receipt, etc.; c) any product traceability reference which relates to the unit sampled.
