20、, at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by June 2006. This European Standard supersedes EN 1067:1997. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement th

21、is European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

This European Standard does not purport to address all of the safety problems

23、, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices 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

24、 for testing, and the procedure for preparing a test sample by blending and reduction of a series of samples representative of 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

25、 indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 923, Adhesives Terms and definitions EN ISO 15605, Adhesives Sampling (ISO

26、15605:2000) ISO 565, Test sieves Metal wire cloth, perforated metal plate and electroformed sheet Nominal sizes of openings ISO 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

27、 For the purposes of this European Standard, the definitions given in EN 923 apply. 4 Sample container 4.1 Condition of container 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

28、it is being taken specifically to determine the extent to which the adhesive has been affected. 4.2 Opening of container Some 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

29、 container, particularly if bulging of the lid or the bottom of the container is observed. If such phenomena occur, they shall 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

30、of the container shall be removed, particularly around the closure. The container shall be opened with care so as not to disturb the contents.

31、 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 of the total capacity of the container. 5.1.2 Surface skin Record the presence of any surf

32、ace 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 container and remove it, if necessary by sieving. Record the ease of removal. 5.1.3 Consistency R

33、ecord 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 whereas the consistency of the former is markedly reduced by stirring or shaking, the consisten

34、cy 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 any visible impurities, record their presence and remove them if possible. 5.1.6 Sediment If

35、 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 any resultant health hazards. Before handling the product the precautions indicated on it

36、s 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.Licensed Copy: Wang Bin, na, Wed Apr 12 09:18:05 BST 2006, Uncontrolled Copy, (c) BSIEN 1067:2005 (E) 6 6 Preliminary p

38、.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 of r

39、emoval. 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 stirr

40、ing 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 inside

41、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 hazards. 6.

42、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.Licensed Copy: Wang Bin, na, Wed Apr 12 09:18:05 B

43、ST 2006, Uncontrolled Copy, (c) BSIEN 1067:2005 (E) 7 6.2.2 General During all the 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

44、.3 Removal of skin If the original sample contained skin, remove any remnants by 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 i

45、f there is no perceptible settling. NOTE If the samples is less than 250 g a palette 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.

46、 Repeat the alternate stirring and shaking until the contents are completely homogeneous. 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 po

47、ssible, entrainment of air. The samples shall be free from air bubbles before use. 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

48、 fluid medium into a clean container. Remove the settled pigment from the bottom 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 befor

49、e the next is made. Complete the reincorporation by pouring from one container to 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-duty 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
