15.1 ObjectThe purpose of this test is to verify that microduct is capable of withstanding the maximum internal pressure used for blowing of microduct cable or fibre unit.15.2 GeneralThis test ensures safe operation over a range of temperatures. The test pressure is chosen to be either the maximum working pressure of the microduct or a…

4 Test method4.1 GeneralThis part of IEC 60811 shall be used in conjunction with IEC 60811-100.Unless otherwise specified, tests shall be carried out at room temperature.Two test procedures can be applied to materials, depending on cable system conditions andenvironments; a summary of test conditions is given in Table 1:– for less severe conditions: Method A;–…

4 PrincipleA test specimen is clamped over an expansive diaphragm by means of a circular clamping ring. Increasing fluid pressure is applied to the underside of the diaphragm, causing distension of the diaphragm and the fabric. The volume of fluid is increased at a constant rate per unit time until the test specimen bursts. The…

6.4 Vertical flame 6.4.1 General 6.4.1.1 This test establishes the method for determining the resistance of MPT, fitting, or clamp to the vertical propagation of flame and dropping of flaming particles Specimens shall be separately subjected to two 15-second applications of flame, with 15 seconds between each Raine application 6.4.1.2 Specimens shall be tested in…

6 Apparatus and Materials6.1 Flammability Tester,with a separate timer capable of providing flame impingement on the specimen for 1 + 0.01 s as shown in Fig. 1 or an equivalent electrically operated tester equipped with an automatic electric timer, as described in Annex A1. Testers are normally supplied with specimen holders.6.2 Brushing Device, as shown…

3 Fire behaviour3.1 Requirements and testingThe material used for pipes and fittings shall fulfil the requirements for class B1 building materials, as specified in DIN 4102-1. Fire behaviour shall be tested as in DIN 4102-1, with the exception of pipes and fittings with wall thicknesses as in DIN 4102-4. 4 Conformity assessment (quality control)4.1 General…
