The work of preparing International Standards is n
9、ormally 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 represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part i
10、n the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prep
11、are International Standards. 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. Attention is drawn to the possibility that s
12、ome of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

15、ethod for determining the resistance against separation of two layers of a resilient floor covering by peeling. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 peel resistance force applied to the width of one layer of a resilient floor cover
16、ing which separates it from the adjacent layer 3 Principle The force required to separate layers of a test piece by peeling is measured. 4 Apparatus 4.1 Tensile testing machine, with suitable load cell and a recording device. The machine shall be capable of maintaining the testing speed required (se
17、e 7.2). 5 Sampling and selection of specimens Take a representative sample from the available material. Take six test pieces at regular distances from the sample, the distance between the outer edge of the sample and the nearest edge of the test piece being at least 100 mm, of minimum length 150 mm
18、and width (50 1) mm, three cut in the machine direction and three cut in the transverse direction (see Figure 1).

20、of (50 5) % for a minimum of 24 h. Maintain these conditions when conducting the test. Take notice of 7.1. 7 Test procedure 7.1 Effect the initial separation of the two layers over a sufficient length to permit the test piece to be fixed in the jaws of the tensile testing machine (Figure 2). If a so
21、lvent is used for initial separation, remove it by storing the test piece in a ventilated oven at 60 C for two hours, followed by normal conditioning as described in Clause 6.

23、apart) of the tensile testing machine so that the tension will be applied evenly over the width of the test piece. Set the machine and its recording device in operation such that the speed of separation is (100 5) mm/min. Record the separation force which continues beyond the initial separation. 7.3
24、 Repeat the test on the remaining test pieces. 8 Calculation and expression of results Ignore the first and last quarter of the full length of the graph for each test piece. Spread a screen as shown in Figure 3 over the graph, and record the forces at the cross points in newtons. Calculate the mean
25、value of the peel resistance (2.1) for each test piece rounded to the nearest 5 N. Also calculate the mean value of the peel resistance for each direction from the measurements taken and express the result rounded to the nearest 5 N in newtons per 50 mm.
