9、ii blankBSISO11377:1997 ii BSI04-1999 Foreword ISO (the International 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
10、 interested in a subject for which a technical committee has been 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 Electrotec
11、hnical Commission (IEC) on all matters of electrotechnical standardization. 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

14、g 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 revision, and parties to agreements based on this International Standard are encourag
15、ed to investigate the possibility of applying the most recent editions of the standards indicated below.

ISO 1957:1986, Machine-made textile floor coverings Sampling and cutting specimens for physical tests. 3 Principle Samples of textile floor covering are exposed to foot traffic at a c
17、ontrolled test site and are evaluated for change in colour after a given level of soiling is reached. The textile floor coverings can be evaluated for soiling in-situ for intermediate assessments and, after removal from the test site, for final assessment. 4 Test site The test site shall be remote f
18、rom outside entrances and isolated from nontypical, greasy, oily or wet traffic. It shall consist of a level corridor of width not more than 1,5 m and not less than 1,3 m, with straight, non-turning traffic in both directions, as shown in Figure 1. The test site may be equipped with a photoelectric
19、traffic counter positioned 1,25 m above floor level. The test site shall not be in areas where people gather, such as those containing bulletin boards or vending machines. The floor shall be level and free from irregularities. At least 2,5 m of buffer textile floor covering, free from contaminants a
20、nd exhibiting minimum fibre shedding, shall be placed at each end of the test textile floor covering. 5 Test specimen preparation Textile floor coverings under test shall be sampled in accordance with ISO 1957 and square test specimens shall be prepared having sides measuring (35010)mm. They shall b
21、e placed in two lines along the length of the corridor (see Figure 1). Buffer textile floor covering between300 mm and 400 mm in width shall be attached to the sides of the test area, so as to fill the width of the corridor. For each sample of floor covering there shall be at least two replicate spe
22、cimens. 6 Textile floor covering installation Textile floor coverings shall be installed in such a way that they ensure safe traffic. This is easily achieved with double faced pressure-sensitive adhesive tape. Alternatively, individual specimens may be mounted to a removable rigid or semi-rigid subs
23、trate of size identical to the test specimens and inserted into the test area. Where traffic crosses from hard flooring to textile floor covering and vice versa, the textile floor covering edge shall be secured with rubber, plastic or metal edging, or tape to prevent a tripping hazard. Care shall be
24、 taken to minimize textile floor covering junctions where there are large differences in carpet thickness and other potential tripping hazards. NOTEIf it is deemed beneficial to identify the site as one where a trial is in progress, it is recommended that any safety signs which are used conform to I
25、SO 3864. When first installed, the test specimens shall be placed in alternating positions. For example, if there are two sets of replicate specimens, A and B, they shall be placed AB/BA across the width of the test site; if there are three sets of replicate specimens, A, B and C, they shall be plac
26、ed AB/CA/BC; and if there are four sets of replicate specimens, A, B, C and D they shall be placed AB/CD/BA/DC (see Figure 2). 7 Test procedure 7.1 To ensure even soiling, systematic transfer of test specimens between lines shall take place every two days, or after a predetermined number of traffick
27、s, with specimens being rotated 90 in a clockwise direction, moved two places down the length of the corridor and moved to the other line. Replicate specimens shall be placed away from each other where possible within the test area (see Figure 2) to help to assess whether even soiling has taken plac

29、e forwards, in order to give all parts of all specimens equal treatment, as follows. The first two double strokes shall be made with the vacuum cleaner suction slot approximately 50% on the buffer carpet and 50% over the test area. Each subsequent series of strokes is made parallel to the first seri
30、es with50% overlap, ending when the buffer strip at the other side is included in the overlap. 7.3 Test specimens shall be trafficked until soiling has reached a predetermined level for one of the sets of specimens which has been selected as a reference, after a predetermined number of trafficks or
31、after a fixed period of time. The predetermined soiling level is assessed to a grey scale level (e.g.level3) or the colour difference measured instrumentally. Alternatively, a standard or control specimen may be included in every test and compared with presoiled samples of the standard or control sp
32、ecimen which are held in the laboratory. 8 Evaluation Prior to evaluation the specimens shall be suction cleaned in accordance with the procedure described in 7.2. The soiling level of each test specimen shall be assessed using at least one of the following techniques a) colour measurement device de
33、scribed in ISO105-J01; b) grey scales and procedure described in ISO105-A02; c) visual comparative ranking. Figure 2 Examples of test specimen layoutsBSISO11377:1997 4 BSI 04-1999 When using colour measurements, colour change shall be expressed as the difference between the soiled specimen and the u
34、ntrafficked control. NOTECaution should be employed when measuring colour difference, since pile flattening and the method of introducing the test specimen to the instrument can profoundly influence results. 9 Test report The test report shall include the following information: a) all the informatio
35、n necessary for complete identification of the textile floor coverings being tested; b) a reference to this International Standard; c) the purpose of the test; d) a description of the test site with lay-out of test specimens at the start and at the completion of the test; e) the rotation and transfe
36、r procedure 7.1; f) a description of the maintenance procedure (including type of vacuum cleaner used); g) the predetermined level to which one of the sets of test specimens was soiled, the number of trafficks or the length of time test specimens were on the floor; h) the method(s) of evaluation; i)
37、 the test results; j) additional information which may have affected the results, e.g. relative humidity and temperature measurements of the test site during the test period; k) a statement that the results obtained are valid only within the test site; l) the date of the test.BSISO11377:1997 BSI 04-
