22、ional Organization for Standardization) is a 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 bee
23、n established has the right to be represented 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 stan
24、dardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 9665 was prepared by Technical Co
25、mmittee ISO/TC 61, Plastics, Subcommittee SC 11, Products. This second edition cancels and replaces the first edition (ISO 9665:1993), annex A of which has been updated.

26、on South Bank University, Tue Jan 30 01:36:11 GMT+00:00 2007, Uncontrolled Copy, (c) BSI iii Introduction The physical and chemical properties of animal glue depend firstly on the nature of the raw material and secondly on the methods of processing. It is not possible to develop any simple tests tha
27、t will evaluate completely the quality of a glue, or its suitability for a particular use. If, however, the glue is made from a specific type of raw material by a usual method of manufacture, then the following tests provide indications of the behaviour of the glue in use, and may be taken as reliab
28、le criteria of quality. Amongst these properties, the gel strength or viscosity, or both, are usually included as general indices of quality. The foam test is of interest when the glue is to be applied by special machines. Many of the physical tests (e.g. gel strength, water absorption, foam) are of
29、 an empirical character, but if the methods are carefully followed consistent results are obtainable which will provide useful information both to the manufacturer and user. Small samples of glue rapidly change their moisture content in response to changes in atmospheric humidity. It is essential to
30、 keep the moisture content of samples unchanged after they are taken. The use of sealed waterproof storage containers is recommended for this purpose. If a consignment undergoes long delays in transit, the average moisture content may change between the times of sampling by producer and consumer. To
31、 avoid this problem causing unnecessary disputes, it is recommended that, when gel strengths or viscosities are reported, the results of moisture content tests should also be given, if an accurate comparison is required. Although the remaining tests listed in table 1 may also be slightly affected by
32、 changes in moisture content, the differences are not significant and it is not necessary to report moisture contents for them.

34、in glues in the form of powder, granules, pearls or cubes. NOTE 1 The methods may be extended to the testing of other forms of animal glues by suitable calculation of the equivalent dry glue content. The precision of the test methods included in this International Standard is not known because inter
35、laboratory data are not available. When interlaboratory data are obtained, precision statements will be added to the corresponding test methods at the next revision. NOTE 2 For details of precision statements, refer to ISO 5725-1:1994, Accuracy (trueness and precision) of measurement methods and res
36、ults Part 1: General principles and definitions. 2 Normative references The following standards contain provisions 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
37、revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 3105:1994, Glass cap

41、 1 kg test sample represents the whole consignment. 4.2 Initial selection of sample The containers shall be selected from various parts of the consignment in such a manner that the widest representation is obtained. The number of containers to be sampled shall be fixed by agreement between purchaser
42、 and vendor. State the number of containers sampled in the test report. From containers of 50 kg or more of glue, take a sample weighing not less than 1 kg when there is only one container, and an increment of not less than 500 g from each container when there is more than one; from containers of le
43、ss than 50 kg of glue take a proportionate amount. This sample is called the preliminary sample. Take appropriately sized samples by means of a sampling tube, scoop or similar tool to ensure that glue is taken from the top, middle and bottom of the container. Store these preliminary samples in clean
44、, dry, airtight, non-absorbent containers until required. NOTE For further guidance, reference should be made to ISO 3951:1989, Sampling procedures and charts for inspection by variables, for percent nonconforming, and ISO 8213:1986, Chemical products for industrial use Sampling techniques Solid che
45、mical products in the form of particles varying from powders to coarse lumps. 4.3 Final selection of sample Mix the preliminary samples thoroughly and take one or more samples from the bulk, each weighing not less than 1 kg, and store them in clean, dry, airtight, non-absorbent containers. These sam
46、ples shall be known as the laboratory samples. 5 Preparation of test sample 5.1 Reduction of solid (powdered, pearl, cube and granulated) glue sample Grind the sample by hand in a mortar, or alternatively in a laboratory disintegrator, of a type capable of grinding the sample to a particle size of 3
47、 mm or smaller. This sample is called the test sample. If necessary, quarter this sample in the usual manner to bring the final mass to 500 g, taking care that a representative amount of all particle sizes is included in the quartering. Keep the powdered samples so obtained in two air-tight containe
48、rs, one container for the test sample for moisture content (see clause 6) and the second container for all other tests. The type of disintegrator used to grind the sample shall be agreed on between the purchaser and vendor because different types of disintegrator generate different amounts of heat a
49、nd have different effects on the moisture content of the sample. Because of the loss of moisture in grinding, take a separate sample for the moisture content test from the material obtained by the preliminary breaking up, before the material is put through the disintegrator. This small separate sample is then powdered by hand in a mortar and pestle, or cut with scissors, and is suitable for the moisture content test. Make adjustment for the moisture content of the mechanically ground sample by comparison with the h
