15、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 body interested in a subject for which a technical committee has been established has the right to be represented

16、 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are draft

17、ed in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Stan

18、dard requires approval by at least 75 % of the member bodies casting a vote. Attention 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 responsible for identifying any or all such patent rights. ISO 1513 was prepared by

19、 Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes. This fourth edition cancels and replaces the third edition (ISO 1513:1992), which has been technically revised. It also incorporates the Technical Corrigendum ISO 1513:1992/Cor.1:1

20、994. The main technical changes are: a) the title has been changed to “Examination and preparation of test samples”; b) the normative references have been updated; c) a definitions clause with definitions of thixotropy and homogenization has been added; d) the examination and mixing procedures for l

21、iquid and paste-like products have been combined into a single clause (Clause 5); e) the type of sieve to be used for straining the sample is no longer specified.

22、ion and preparation of test samples 1 Scope This International Standard specifies 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

23、 or bulk of paint, varnish or related product. NOTE The samples of the product to be tested are assumed to conform to ISO 15528. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For

24、 undated references, the latest edition of the referenced document (including any amendments) applies. ISO 4618, Paints and varnishes Terms and definitions ISO 15528, Paints, varnishes and raw materials for paints and varnishes Sampling 3 Terms and definitions For the purposes of this document, the

25、terms and definitions given in ISO 4618 and the following apply. 3.1 thixotropy decrease in the apparent viscosity of a liquid under shear stress followed by a gradual recovery when the stress is removed NOTE The effect is time-dependent. 3.2 homogenization process of combining components, particles

26、 or layers of the original samples (in the case of composite samples) or of pre-treated fractions of samples into a more homogeneous state in order to ensure equal distribution of the substances in, and properties of, the sample 4 Sample container 4.1 Condition of container Record any defects in the

27、 sample container and any visible leakage. If it is possible that the contents have been affected, the sample shall be rejected. BS EN ISO 1513:2010ISO 1513:2010(E) 2 ISO 2010 All rights reserved4.2 Opening of container WARNING Some paints and related products (such as paint removers) are prone to d

28、evelop gas or vapour pressure during storage. Care should be taken in opening containers, particularly if bulging of the lid or the bottom of the container is observed. If such phenomena occur, they should be noted in the report (see Clause 9). Remove all packing materials and other debris from the

29、outer surface of the container, particularly around the closure. Open the container carefully, taking care not to disturb the contents. 5 Preliminary procedure for liquid products (e.g. paint) and paste-like products (e.g. putty) 5.1 Visual examination 5.1.1 Surface skin Record the presence of any s

30、urface skin and whether the skin is continuous, hard, soft, thin or excessively thick. If skin is observed on the sample, it is preferable to discard the sample. If this is impractical, detach the skin as completely as possible from the sides of the container and remove it, if necessary by straining

31、. For analytical test purposes, where skin is present, it might be necessary to disperse the skin and include it in the test sample. 5.1.2 Consistency Record whether the sample is thixotropic or whether gelling has taken place, taking care not to confuse gelling and thixotropy. NOTE Both thixotropic

32、 and gelled coating materials have a jelly-like consistency but, whereas the consistency of the former is markedly reduced by stirring or shaking, the consistency of a gelled coating material cannot be changed in this way. 5.1.3 Separation into layers Record any separation of the sample into layers.

33、 5.1.4 Visible impurities lf there are any visible impurities, record their presence and remove them if possible. 5.1.5 Clarity and colour In the case of varnishes, thinners, catalyst solutions, etc., record the clarity and colour of the sample. 5.1.6 Sediment Record the type of sediment (if any), f

34、or example soft, hard or hard-dry. If the sediment is hard and appears dry and crumbly inside a lump when cut with a clean palette knife, describe it as “hard-dry”. BS EN ISO 1513:2010ISO 1513:2010(E) ISO 2010 All rights reserved 35.2 Homogenization 5.2.1 Limitations Samples which have gelled or sho

35、w a hard-dry sediment (see 5.1.6) which cannot be effectively reincorporated shall not be used for test purposes. 5.2.2 General During all the operations specified in 5.2.3 to 5.2.5, take care to ensure minimum loss of solvent. To this end, carry out all the operations as rapidly as practicable, con

36、sistent with satisfactory mixing. 5.2.3 Removal of skin If the original sample contained skin, detach and remove any remnants by straining the incorporated sample through a sieve. 5.2.4 If no compact sediment is present Mix the sample thoroughly until it is completely homogenous. At all times during

37、 the sample preparation, avoid, as far as possible, entrainment of air. The sample shall be free from air bubbles before use. 5.2.5 If compact sediment is present If it is required to complete the examination of a sample in which compact sediment is present (but not hard-dry sediment, see 5.2.1), pr

38、oceed as follows. Pour all the liquid present into a clean container. Remove the settled pigment from the bottom of the original container with a palette knife and mix thoroughly. When a uniform consistency has been achieved, return the liquid to the original container, a small portion at a time, ca

39、refully incorporating each addition before the next is made. The sample shall be free from air bubbles before use. 6 Preliminary procedure for products in powder form No special procedure is usually required for these products, but unusual features shall be recorded, such as abnormal colour, the pre

40、sence of large or hard lumps or the presence of foreign matter. 7 Blending and reduction of a series of samples 7.1 General In cases where a series of samples has been taken from a homogeneous product, they may either be tested separately or be combined to produce a reduced sample as specified in 7.

41、2 and 7.3. 7.2 Liquid and paste-like products After thoroughly mixing each sample as specified in 5.2, pour or otherwise transfer the samples into a clean, dry container of suitable size and thoroughly mix them by stirring, shaking, etc. When the mixed sample appears to be homogeneous, take a reduce

42、d sample in accordance with ISO 15528. Place the reduced sample in one or more clean, dry containers, allowing 5 % ullage, then close, label and, if necessary, seal the containers. BS EN ISO 1513:2010ISO 1513:2010(E) 4 ISO 2010 All rights reserved7.3 Products in powder form Empty the contents of the

43、 various sample containers into a clean, dry container of suitable size and mix thoroughly. Reduce the sample to a suitable size, e.g. 1 kg to 2 kg, by quartering either manually or by means of a rotary sample divider (riffle divider), then place the reduced sample in one or more clean, dry containe

44、rs. Close, label and, if necessary, seal the containers. 8 Labelling of sample containers State the following particulars, if known, on the label of the sample container: a) the name of the manufacturer and a description of the product; b) the date of manufacture; c) the size and other details of th

45、e consignment; d) the place of sampling, the date of sampling and the name of the sampler; e) the reference number or numbers of the batch, storage tank, drum, etc., from which the sample or samples were taken; f) the date of blending and the name of the blender; g) a reference to this International

46、 Standard (ISO 1513). If the sample is despatched to another laboratory, a delivery note shall be sent with it repeating the details given on the label and also, if required (for example by the laboratory receiving the sample), a preliminary examination report (see Clause 9). 9 Preliminary examinati

47、on report The report shall contain at least the following information: a) a description of the sample, as indicated on the label (see Clause 8); b) a reference to this International Standard (ISO 1513); c) the appearance, clarity, etc., of the sample; d) a description of any skin observed and of the

48、 straining procedure adopted; e) a description of any sediment observed and of the mixing and re-incorporation procedure adopted (see 5.1.1); f) other preliminary observations, as indicated in Clauses 4 and 5.
