EN 1067:2005 (E) 4 SAFETY STATEMENT: Persons u

21、sing this European Standard should be familiar with the normal laboratory practice, in principle. This European Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices

22、and to ensure compliance with any regulatory conditions. 1 Scope This European 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 o

23、f a consignment or bulk of adhesives or related product. It is intended for use in conjunction with EN ISO 15605. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undat

24、ed references, the latest edition of the referenced document (including any amendments) applies. EN 923, Adhesives Terms and definitions EN ISO 15605, Adhesives Sampling (ISO 15605:2000) ISO 565, Test sieves Metal wire cloth, perforated metal plate and electroformed sheet Nominal sizes of openings I

25、SO 8213, Chemical products for industrial use Sampling techniques Solid chemical products in the form of particles varying from powders to coarse lumps 3 Terms and definitions For the purposes of this European Standard, the definitions given in EN 923 apply. 4 Sample container 4.1 Condition of conta

26、iner Any defects in the sample container or any visible leakage shall be recorded. If it is possible that the contents have been affected, the sample shall be rejected unless it is being taken specifically to determine the extent to which the adhesive has been affected. 4.2 Opening of container Some

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

28、l be noted in the report of preliminary examination (see Clause 12 f). All packing materials (for example polystyrene chips, saw-dust) and other debris from the outer surface of the container shall be removed, particularly around the closure. The container shall be opened with care so as not to dist

29、urb the contents. EN 1067:2005 (E) 5 5 Preliminary procedure for fluid products consisting of a single homogeneous liquid phase or two liquid phases 1)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

30、of the total capacity of the container. 5.1.2 Surface skin Record the presence of any surface skin and its type, i.e. whether continuous, whether hard or soft and whether thin or moderately or excessively thick. If any skin is present detach it as completely as possible from the sides of the contain

31、er and remove it, if necessary by sieving. Record the ease of removal. 5.1.3 Consistency Record whether the sample is thixotropic or whether gelling has taken place, taking care not to confuse gelling and thixotropy. NOTE Both thixotropic and gelled adhesives have a jelly-like consistency, but where

32、as the consistency of the former is markedly reduced by stirring or shaking, the consistency of a gelled adhesive cannot be reduced in this way. 5.1.4 Separation of phases Record any separation of the sample into layers, for example water and resinous matter. 5.1.5 Visible impurities If there are an

33、y visible impurities, record their presence and remove them if possible. 5.1.6 Sediment If there is any appreciable sediment, record its presence and appearance. 5.1.7 Clarity Record the clarity and colour of the sample. 5.1.8 Odour Record any odour detected. NOTE Care should be taken with regard to

34、 any resultant health hazards. Before handling the product the precautions indicated on its safety data sheet should be referred to. 5.2 Mixing Thoroughly stir the sample and incorporate any slight sediment. 1)These correspond to products of type A and B in EN ISO 15605.EN 1067:2005 (E) 6 6 Prelimin

35、ary procedure for fluid products consisting of one or two liquid phases together with one or more solid phases 2)6.1 Visual examination 6.1.1 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

36、. 6.1.2 Surface skin Record the presence of any surface skin and its type, i.e. whether continuous, whether hard or soft, and its approximate thickness. If any skin is present, detach it as completely as possible from the sides of the container and remove it, if necessary by sieving. Record the ease

37、 of removal. 6.1.3 Consistency Record whether the adhesive is thixotropic or whether gelling has taken place, taking care not to confuse gelling and thixotropy. NOTE Both thixotropic and gelled adhesives have a jelly-like consistency, but whereas the consistency of the former is markedly reduced by

38、stirring or shaking, the consistency of a gelled adhesive cannot be reduced in this way. 6.1.4 Separation of phases Record any separation of the samples into phases. 6.1.5 Settling Record the type of settling, for example soft, hard or hard-dry. If the settling is hard and appears dry and crumbly in

39、side a lump when cut with a clean palette knife, describe it as hard-dry. 6.1.6 Extraneous matter Remove any extraneous matter in the adhesive as carefully as possible and record its presence. 6.1.7 Odour Record any odour detected. NOTE Care should be taken with regard to any resultant health hazard

40、s. 6.2 Mixing 6.2.1 Limitations Samples which have gelled or show hard-dry settling (see 6.1.3 and 6.1.6) cannot be effectively made homogeneous and shall therefore not be used for testing purpose. 2)These correspond to products of type C in EN ISO 15605.EN 1067:2005 (E) 7 6.2.2 General During all t

41、he operations specified in 6.2.3 to 6.2.5 care shall be taken to ensure minimum loss of solvent. To this end, all the operations shall be carried out as rapidly as practicable and consistent with satisfactory mixing. 6.2.3 Removal of skin If the original sample contained skin, remove any remnants by

42、 straining the incorporated sample under its own weight, through a sieve conforming to ISO 565, of nominal aperture 125 m unless otherwise specified. 6.2.4 No occurrence of hard settling Mix the sample thoroughly, even if there is no perceptible settling. NOTE If the samples is less than 250 g a pal

43、ette knife is preferred as an alternative to the stouter stirrer normally used for larger samples. Firmly replace the lid of the container and thoroughly shake the contents, inverting the container as this is being done. Repeat the alternate stirring and shaking until the contents are completely hom

44、ogeneous. As an added precaution, it is recommended that the mixing 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 samples shall be free from air bubbles before us

45、e. 6.2.5 Occurrence of hard settling The examination of a sample in which hard settling has occurred (but not hard-dry settling, see 6.2.1) shall be completed in accordance with the procedure detailed below. Pour all the fluid medium into a clean container. Remove the settled pigment from the bottom

46、 of the container with a palette knife and mix thoroughly. When a uniform consistency has been achieved, return the 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 t

47、o the other several times (see 6.2.4). Ensure that the sample is free from air bubbles before use. 7 Preliminary procedure for viscous products3)Examine these products in general as for fluid products under Clause 6. NOTE Where mixing appears to be necessary to ensure homogeneity, a small, heavy-dut

48、y mixer can be used. 8 Preliminary procedure for products in powder form 4)No special procedure is normally required for these products. Unusual features such as abnormal colour, the presence of large or hard lumps, or the presence of foreign matters shall be recorded. 3)These correspond to products

49、 of type D in EN ISO 15605.4)These correspond to products of type E in EN ISO 15605.EN 1067:2005 (E) 8 9 Preliminary procedure for solid products not in powder form 5)No special procedure is normally required for these products. Unusual features such as abnormal colour, the presence of foreign matter shall be recorded. 10 Blending and reduction of a series of samples 10.1 General In cases where a series of samples have been taken from a homogeneous product, either test these separately, or combine them to produce a reduced sample as specified in 10.2 to 10.
