Foreword3DIN EN ISO 15528:2013-12EN ISO 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 1513,1s
24、pecifies 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 be te
25、sted 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 Intern
26、ational 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 operator
27、s 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.4DIN EN ISO 15528:2013-12EN ISO 15528:2013 (E) 1 ScopeThis International Standard
28、 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 capable of being liquefied when heated up, and powdered, granulated and pasty materials. Samples m
29、ay 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 not deal with the sample preparation for testing or reduction of the samples thus taken.

After selection of a clean sampling device of a suitable type and size, sampling shall be performed observing the relevant regulations on environment, health and safety.The sampling method used shall take into account both the physical and the chemical characteristics of the material concern
38、ed, e.g. its sensitivity to light and oxidation, its tendency to undergo surface reactions (skin formation) and its hygroscopic, physiological and toxicological characteristics.Storage of the samples, including the storage samples, shall comply with relevant regulations on environment, health and sa
39、fety, and the quality management requirements concerning labelling, traceability and periods of storage.5 Sampling equipment5.1 Sampling devices5.1.1 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,
40、 and the sample size required. General requirements for sampling devices include easy handling, easy cleaning (smooth surfaces), chemical resistance to the material being sampled.6DIN EN ISO 15528:2013-12EN ISO 15528:2013 (E) 5.1.2 Scoops5.1.2.1 Scoop (ladle) (see also 5.1.7)A scoop shall consist of
41、 a material which is not altered by the product to be tested. It is primarily used for taking top samples of solid materials.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 l
42、ength to open and close compartments (see Figure 1). It is normally from 25 mm to 50 mm in diameter.The instrument is inserted closed and the shutter pulled out to admit the liquid; the scoop is then closed and withdrawn.Key1 trough2 shutterFigure 1 Sample scoop for liquids7DIN EN ISO 15528:2013-12E
43、N ISO 15528:2013 (E)5.1.2.3 Scoops for powdersSuch scoops are open instruments intended for use with solids in powder form. 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 Sam
44、pling tubes for liquids5.1.3.1 Concentric tubesThese consist of two concentric metal tubes which fit 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 i
45、n both tubes. In one position the tube is open and admits the liquid; by turning the inner tube it 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 th
46、eir lower ends, placed so that liquid contained in the instrument can be drained through them when 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.
47、 Such an arrangement enables separate samples of liquid to be withdrawn from different depths in the 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.8DIN EN ISO 15528:2013-

It consists of a metal or thick-walled glass tube w
49、hich may vary from 20 mm to 40 mm in diameter and from 400 mm to 800 mm in length. The upper and lower ends are conical and narrow down to about 5 mm to 10 mm. At the upper end there are two rings to assist in handling.To take an individual sample, the tube is first closed at the top with a stopper, and lowered until the desired depth is reached. It is opened for a short time to admit the liquid and then closed and withdrawn.9DIN EN ISO 15528:2013-12EN ISO 15528:
