4 Test facility4.1 GeneralThe SBI test facility shall consist of a test room, the test apparatus (trolley, frame, burners, hood, collector and ducting), the smoke exhaust system and general measuring equipment. These components are specified in 4.2 to 4.7. Design drawings are given in Annex E. Dimensions given in the drawings are nominal unless tolerances…

8.4 Determination of flexing resistance of outsole 8.4.1 Rigidity test8.4.1.1 Apparatus8.4.1.1.1 Smooth metal hinged plate, fixed to a rigid base.8.4.1.1.2 Clamping device, to fix the forepart of the footwear to be tested to the rigid base.8.4.1.1.3 Sensor, capable of measuring force in the range 0 N to 50 N, to a tolerance of ±1 %,…

4 Apparatus4.1 Constant-elongation measurements4.1.1 Straining device, consisting of a metal rod or other suitable guide fitted with pairs of holders, onefixed and one moveable, for the ends of the test piece. The holders shall be in the form of self-tighteningclamps for strip test pieces, in the form of jaws to hold tab (enlarged) ends, and…

6.6 Determination of water vapour permeability (WVP) 6.6.1 PrincipleThe test piece is fixed over the opening of a jar, which contains a quantity of solid desiccant. This unit is placed in a strong current of air in a conditioned atmosphere.The air inside the container is constantly agitated by the desiccant, which is kept in movement…

Apparatus4.1 The apparatus required for salt spray (fog) exposure consists of a fog chamber, a salt solution reservoir, a supply of suitably conditioned compressed air, one or more atomizing nozzles, specimen supports, provision for heating the chamber, and necessary means of control. The size and detailed construction of the apparatus are optional, provided the conditions…

L.1 Lap shear strength of tape coatingsL.1.1 GeneralThe test consists of measuring the lap shear strength (maximum force per unit area) obtained in shearing a single overlap joint between a plate with metallic surface or plant coating and the FJC by applying a tensile force that is parallel to the bond area and to the…

6. Requirements 6.1 Dimensions and Tolerances: 6.1.1 Dimensions and tolerances shall be as shown in Table 1 and Table 2 when measured in accordance with Test Method D2122. The tolerances for out-of-roundness shall apply only to pipe prior to shipment. 6.2 Sustained Pressure—The pipe shall not fail, balloon, burst, or weep as defined in Test…

4 PrincipleThe test mixture, consisting of a color concentrate and a basic test polymer, is passed through an extruder fitted with melt pump and screen pack with breaker plate. In front of the screen pack is a melt pressure transducer. The pressure difference between the start pressure and the maximum pressure is used to calculate…

4    Principle A cyclic tensile test with a constant load range is imposed on a cylindrical specimen under suitable test conditions within the stress range where SCG is achieved. A circumferential notch is machined in the center of the test specimen to enable crack initiation and SCG to the final failure of the specimen. The…
