    12、 the seams of resilient floor coverings when welded in accordance with the manufacturers instructions. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 seam strength maximum tensile force recorded, for a defined width, when a floor covering is

    13、 tested under a constant rate of extension 2.2 constant-rate-of-extension (CRE) testing machine tensile testing machine provided with one clamp which is stationary and another clamp which moves with a constant speed throughout the test, the entire testing system being virtually free from deflection

    14、3 Principle An increasing tensile force is applied until the seam breaks (see Figure 1; the arrows indicate the direction of the applied tensile forces). Figure 1 Principle of test 4 Apparatus A tensile testing machine, which allows a speed of separation of (100 5) mm/min, and a force recording devi

    16、minimum length of 1 m and minimum width of 300 mm and weld them together in accordance with the manufacturers instructions. The weld shall be done on the long side of the sample. For tiles, weld two tiles together in accordance with the manufacturers instructions. Cut five test pieces with minimum l

    17、ength of 150 mm and width of (50 0,5) mm at equal distances across the sample, the distance between the outer edge of the sample and the nearest edge of the test piece being at least 100 mm, with the seam centrally located across each test piece (see Figure 2).

    18、 seam Figure 2 Test piece layout 6 Conditioning Condition the test pieces at a temperature of (23 2) C and relative humidity of (50 5) % for a minimum of 24 h. Maintain these conditions when carrying out the test. 7 Procedure Place the test piece in the jaws (which are approximately 100 mm apart) of

    19、 the tensile testing machine so that the seam is at an equal distance from the jaws and tension is applied evenly over the width. Set the machine and its recording device in operation such that the speed of separation is (100 5) mm/min. Record the force at break or the maximum force exerted. Repeat

    20、the test on the remaining test pieces to obtain five values.2 ISO 2015 All rights reserved ISO 16906:2015(E) 8 Calculation an expression of results Calculate the mean value of the five tests and express the result to the nearest 10 N in N/mm. Also record the minimum of the individual values. 9 Test

    21、report The test report shall contain the following information: a) a reference to this International Standard, i.e. ISO 16906; b) a complete identification of the product tested, including type, source, colour, and manufacturers reference numbers; c) previous history of the sample; d) a description

    22、of the welding process; e) the mean value of seam strength; f) the minimum value of seam strength; g) the type of failure if not in the seam, e.g. failure due to breaking of the test piece; h) any deviation from this International Standard which could have affected the results.
