17、.12BS EN ISO 15528:2013ISO 15528:2013(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member bod
18、y interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrote
19、chnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO
20、 documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAttention 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 responsibl
21、e for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received. www.iso.org/patentsAny trade name used in this document is information given for the con
22、venience of users and does not constitute an endorsement. The committee responsible for this document is ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes.This second edition cancels and replaces the first edition (ISO 15528:2000), which has been techn
23、ically revised. The main changes are:a) the detailed information on how to achieve homogeneity of the product to be sampled was removed;b) the sampling procedure for large containers and small containers was merged;c) the information on the minimum number of containers to be sampled was removed;d) d
24、efinitions for middle sample and all-layer sample were added.iv ISO 2013 All rights reservedBS EN ISO 15528:2013ISO 15528:2013(E)IntroductionSampling depends on the product and the size of the container but not on the type of product, e.g. paint, varnish, binder, pigment, extender or solvent. ISO 15
25、13,1specifies both the procedure for preliminary examination of a single sample as received for testing, and the procedure for preparing a test sample by blending and reduction of a series of samples representative of a consignment of paint, varnish or related product. The samples of the product to
26、be tested have been taken in accordance with this document.Correct sampling forms the basis for the subsequent tests and their results. The various sampling procedures need to be carried out with great care by operators having the required knowledge and experience. The general instructions in this I
27、nternational Standard are intended to supplement this knowledge and experience and are applicable to most situations. However, some products might require special sampling precautions that are not given in this International Standard; therefore, special vigilance will be necessary on the part of ope
28、rators to take note of any unusual characteristics exhibited by those products. It is also essential that operators adhere to any special precautions in accordance with product specifications and national safety regulations.

29、s, varnishes and raw materials for paints and varnishes Sampling1 ScopeThis International Standard specifies procedures for the sampling of paints, varnishes and raw materials used in their manufacture. Such products include liquids and materials which, without undergoing chemical modification, are
30、capable of being liquefied when heated up, and powdered, granulated and pasty materials. Samples may be taken from containers, e.g. cans, drums, tanks, tank wagons or ships tanks, as well as from barrels, sacks, big-bags, silos or silo wagons, or from conveyor belts.This International Standard does
31、not deal with the sample preparation for testing or reduction of the samples thus taken. This is dealt with in ISO 1513.12 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

After selection of a clean sampling device of a suitable type and size, sampling shall be performed observing the relevant regulatio
39、ns on environment, health and safety.The sampling method used shall take into account both the physical and the chemical characteristics of the material concerned, e.g. its sensitivity to light and oxidation, its tendency to undergo surface reactions (skin formation) and its hygroscopic, physiologic
40、al and toxicological characteristics.Storage of the samples, including the storage samples, shall comply with relevant regulations on environment, health and safety, and the quality management requirements concerning labelling, traceability and periods of storage.5 Sampling equipment5.1 Sampling dev
41、ices5.1.1 GeneralThe choice of sampling device depends on the type of material being sampled, the type of container, the level to which the container is filled, and the sample size required. General requirements for sampling devices include easy handling, easy cleaning (smooth surfaces), chemical re
42、sistance to the material being sampled.2 ISO 2013 All rights reservedBS EN ISO 15528:2013ISO 15528:2013(E)5.1.2 Scoops5.1.2.1 Scoop (ladle) (see also 5.1.7)A scoop shall consist of a material which is not altered by the product to be tested.

43、ials.5.1.2.2 Scoop for liquidsThis instrument consists of a D-shaped metal trough divided into compartments along its length, and a shutter that moves vertically along the entire length to open and close compartments (see Figure 1). It is normally from 25 mm to 50 mm in diameter.The instrument is in
44、serted closed and the shutter pulled out to admit the liquid; the scoop is then closed and withdrawn.Key1 trough2 shutterFigure 1 Sample scoop for liquids ISO 2013 All rights reserved 3BS EN ISO 15528:2013ISO 15528:2013(E)5.1.2.3 Scoops for powdersSuch scoops are open instruments intended for use wi

They are of metal, of semicircular or C-shaped cross-section and when inserted bore out a core through the material (see Figure 2).Figure 2 Sampling scoops for powders5.1.3 Sampling tubes for liquids5.1.3.1 Concentric tubesThese consist of two concentric metal tubes which f
46、it closely one inside the other along their entire length, so that one tube can be rotated within the other. A longitudinal opening or series of openings of about one-third of the circumference is cut in both tubes. In one position the tube is open and admits the liquid; by turning the inner tube it
47、 becomes a sealed container (see Figure 3).The inner tube is normally 30 mm to 40 mm in diameter. It may be undivided along its length, in which case the two tubes are provided with V-shaped ports at their lower ends, placed so that liquid contained in the instrument can be drained through them when
48、 the longitudinal opening is open.Alternatively, the inner tube may be divided transversely into a number of compartments, normally from three to 10, in which case the bottom V-shaped ports are omitted. Such an arrangement enables separate samples of liquid to be withdrawn from different depths in t
49、he container.The tube should be of sufficient length to reach the bottom of the container. It is inserted closed, then opened to admit the liquid and finally closed and withdrawn.4 ISO 2013 All rights reservedBS EN ISO 15528:2013ISO 15528:2013(E)Figure 3 Sampling tube consisting of two concentric tubes5.1.3.2 Single tubeA single-tube sampler, an example of which is shown in Figure 4, may be used where the liquid to be sampled is known to be homogeneous in character.
