14、n) 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 been established has the right to be rep
15、resented 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 a
16、re drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. 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 Internatio
17、nal Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document: ?an ISO Publicly Available Specifica
18、tion (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; ?an ISO Technical Specification (ISO/TS) represents an agreement between the members of
19、a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed every three years with a view to deciding whether it can be transformed into an International Standard. Attention is drawn to the possibilit
20、y that some of the elements of this Publicly Available Specification may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/PAS 17984 was prepared by Technical Committee ISO/TC 219, Floor coverings. Annex A of this Publicly Available
21、 Specification is for information only.

22、iculties, any revision should incorporate a number of test method options for dimensional stability to heat, water and combined heat and water and stability out of the plane. In order to establish the utility of this new approach, and to allow the precision of each test method to be established, it
23、was decided to initially publish a document that would allow for further development based on some or all of these methods. When ISO/TC 219 inherited the project from the disbanded ISO/TC 38/SC 12 it decided that the most appropriate publication was a Publicly Available Specification (PAS) and that
24、ISO 2551 would not be withdrawn until PAS 17984 had been thoroughly reviewed for a period following its publication.

33、ptical bench or mechanical device with gauge. 5.1.2Plate glass sheet, marginally smaller than the test specimen, or other means of keeping the specimen flat while measurements are made. This will not be required if the instrument in 5.1.1 incorporates such a glass or metal plate. 5.1.3Steel pins or
34、other appropriate means of indicating the reference points on the test specimen, if necessary. NOTEA suitable piece of equipment incorporating 5.1.1, 5.1.2 and 5.1.3 is given in annex A. 5.2Methods 1 and 3 5.2.1Ventilated drying oven, capable of being controlled at 60 C?2 C, with perforated and lacq

40、rst measurements (l0) on the fully conditioned specimen using, e.g. the method described in annex A. Place the specimen on the rigid perforated tray (5.3.2) with the use surface uppermost, and put it on a shelf in the drying oven (5.2.1) at 60 C?2 C. Keep the specimen in the drying oven for a period
41、 of 24 h. Remove it and place it immediately in a desiccator or similar apparatus (5.2.2) to allow cooling to take place. When its temperature has reached 20 C?2 C, remove the specimen from the desiccator and immediately measure the dimensions (l1) using, e.g. the method described in annex A. Leave
42、the specimens in the standard atmosphere for testing to allow reconditioning to take place, until constant mass is again obtained (see 6.3). Measure the dimensions (l2) to the nearest 0,1 mm, using e.g. the method described in annex A. Note the final appearance of the specimen. 7.2Method 2: Determin
43、ation of dimensional changes after immersion in water Make the first measurements (l0) on the fully conditioned specimen using, e.g. the method described in annex A. Place the specimen on the rigid perforated tray with the use surface uppermost, and immerse it, laid flat, in water to which has been
44、added 0,5 g/l of an efficient wetting agent (5.3.3), calculated on active matter content, at a temperature of 20 C?2 C. Allow the specimen to soak in the water for 2 h, ensuring that it remains submerged throughout. Lift the tray with the specimen from the water, taking precautions to avoid distorti
45、ng its shape. Leave to drain in a horizontal position for 5 min?1 min. Place the specimen on the measuring board (5.1.1) and again measure the dimensions (l1), using e.g. the method described in annex A. Dry the specimen on the tray in the standard atmosphere for testing, as described in clause 6, u
46、sing a forced air draught (5.3.4) if necessary, until constant mass is again obtained as in 6.3. Measure the dimensions (l2) using e.g. the method described in annex A. Note the final appearance of the specimen. 7.3Method 3: Determination of dimensional changes due to the effects of varied heat and
47、water conditions 7.3.1Initial measurement of the specimen Make all measurements on the conditioned specimen when it is completely flat; this can be achieved by use of the glass plate (5.1.2) or other means. On the conditioned specimen, measure the distance between the edges parallel to the direction
48、 of manufacture and between the edges at right angles to the direction of manufacture, each at two locations approximately 200 mm apart. If required by the method of measuring adopted, mark the pair of reference points, e.g. by the use of steel pins (5.1.3), approximately 200 mm apart on the edge pa
49、rallel to the direction of manufacture and also on the edge at right angles to the direction of manufacture. Make all measurements on the back of the specimen to the nearest 0,1 mm. NOTEProducts made of discrete layers, e.g. foam-backed constructions, should be measured on both the backing and the use-surface, and the results of both measurements given in the test report. 7.3.2Determination Place the test specimen, lying freely on the perforated and lacquered shelves, in the drying oven (5.2.1), controlled at 60 C?2 C. Keep the specimen in the drying o
