8、 has been prepared under the direction of the Pigments, Paints and Varnishes Standards Policy Committee. It is identical with ISO 1513:1992 Paints and varnishes Examination and preparation of samples for testing, published by the International Organization for Standardization (ISO). In 1994 the Euro

9、pean Committee for Standardization (CEN) accepted ISO 1513:1992 and its Technical Corrigendum 1:1994 as European Standard EN ISO 1513:1994. This edition supersedes BS 3900-A2:1983, which is withdrawn. The main difference between BS 3900-A2:1983 and this standard is that discarding samples with surfa

10、ce skin is now recommended. The Technical Committee has reviewed the provisions of ISO 565, to which normative reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A related British Standard to ISO 565 is BS 410:1986 Specification for tes

25、1 Scope This International Standard is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products. This International Standard specifies both the procedure for preliminary examination of a single sample as received for testing, and the procedure for

26、preparing a test sample by blending and reduction of a series of samples representative of a consignment or bulk of paint, varnish or related product, the samples of the product to be tested having been taken in accordance with ISO 1512. 2 Normative references The following standards contain provisi

27、ons which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the poss

28、ibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 565:1990, Test sieves Metal wire cloth, perforated metal plate and electroformed sheet Nominal sizes of openings. ISO 1512:1991, Pa

29、ints and varnishes Sampling of products in liquid or paste form. 3 Sample container 3.1 Condition of container Record any defects in the sample container or any visible leakage. If it is possible that the contents have been affected, the sample shall be rejected. 3.2 Opening of a container WARNING S

30、ome paints and related products (such as paint removers) are prone to develop gas or vapour pressure during storage. Care, appropriate to the situation, shall be taken in opening containers, particularly if bulging of the lid or the bottom of the container is observed. If such phenomena occur, they

31、shall be noted in the report (clause 10). Remove all packing materials and other debris from the outer surface of the container, particularly around the closure. Open the container carefully, taking care not to disturb the contents. 4 Preliminary procedure for fluid products such as varnishes, emuls

32、ions, thinners, etc.1) 4.1 Visual examination 4.1.1 Ullage Record the approximate ullage, i.e. the air-space above the contents of the container, expressed as a percentage of the total capacity of the container. 4.1.2 Surface skin Record the presence of any surface skin and whether the skin is conti

33、nuous, hard, soft, thin or moderately 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. Record the ease of remova

34、l. For analytical control purposes, where skin is present, it may be necessary to disperse the skin and include it in the sample for testing. 4.1.3 Consistency Record whether the sample is thixotropic or whether gelling has taken place, taking care not to confuse gelling and thixotropy. NOTE 1Both t

35、hixotropic and gelled varnishes have a jelly-like consistency but, whereas the consistency of the former is markedly reduced by stirring or shaking, the consistency of a gelled varnish cannot be reduced in this way. 4.1.4 Separation into layers Record any separation of the sample into layers, for ex

36、ample water and oily or resinous matter. 4.1.5 Visible impurities If there are any visible impurities, record their presence and remove them if possible. 4.1.6 Sediment If there is any appreciable sediment, record its presence and appearance. 4.1.7 Clarity and colour In the case of varnishes, thinne

37、rs, catalyst solutions, etc., record the clarity and colour of the sample. 4.2 Mixing Thoroughly stir the sample and incorporate any slight sediment. 1) These correspond to type A and B products in ISO 1512.

38、 Copy, (c) BSI EN ISO 1513:1994 4 BSI 09-1999 5 Preliminary procedure for fluid products such as paints2) 5.1 Visual examination 5.1.1 Ullage Record the approximate ullage, i.e. the air-space above the contents of the container, expressed as a percentage of the total capacity of the container. 5.1.2

39、 Surface skin Record the presence of any surface skin and whether the skin is continuous, hard, soft, thin or moderately 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 o

40、f the container and remove it, if necessary by straining. Record the ease of removal. For analytical control purposes, where skin is present, it may be necessary to disperse the skin and include it in the sample for testing. 5.1.3 Consistency Record whether the sample is thixotropic or whether gelli

41、ng has taken place, taking care not to confuse gelling and thixotropy. NOTE 2Both thixotropic and gelled paints have a jelly-like consistency but, whereas the consistency of the former is markedly reduced by stirring or shaking, the consistency of a gelled paint cannot be reduced in this way. 5.1.4

42、Separation into layers Record any separation of the sample into layers. 5.1.5 Settling Record the type of settling, for example soft, hard or hard-dry. If the settling is hard and appears dry and crumbly inside a lump when cut with a clean palette knife, describe it as “hard-dry”. 5.1.6 Extraneous m

43、atter Record the presence of any extraneous matter in the paint and remove it as carefully as possible. 5.2 Mixing 5.2.1 Limitations Samples which have gelled or show hard-dry settling (see 5.1.3 and 5.1.5) cannot be effectively reincorporated and shall therefore not be used for testing purposes. 5.

44、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, consistent with satisfactory mixing. 5.2.3 Removal of skin If the original sample contained skin, detach and remove any

45、 remnants by straining the incorporated sample, under its own weight, through a sieve complying with ISO 565, of nominal aperture 125 4m, unless otherwise specified. 5.2.4 If no hard settling has occurred Mix the sample thoroughly, even if there is no perceptible settling. NOTE 3If the sample is sma

46、ll enough, a palette knife is suitable, but for a larger sample a stouter stirrer is needed. Firmly replace the lid of the container and thoroughly shake the contents, inverting the container while this is being done. Alternately stir and shake the container in this way until the contents are comple

47、tely homogeneous. NOTE 4As an added precaution, it is recommended that the mixing should be completed by pouring the contents into a clean container and back again several times. At all times during the sample preparation, avoid, as far as possible, entrainment of air. The sample shall be free from

48、air bubbles before use. 5.2.5 If hard settling has occurred If it is required to complete the examination of a sample in which hard settling has occurred (but not hard-dry settling, see 5.2.1), proceed as follows. Pour all the fluid medium into a clean container. Remove the settled pigment from the

49、bottom of the original container with a palette knife and mix thoroughly. When a uniform consistency has been achieved, return the fluid medium to the original container, a small portion at a time, carefully incorporating each addition before the next is made. Complete the reincorporation by pouring from one container to the other several time (see 5.2.4). The sample shall be free from air bubbles before use. 6 Preliminary procedure for viscous products such as putties, mastics, etc.3) Examine these products in general as for paints under clause 5
