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…
5 Test methods 5.1 General 5.1.1 Test conditions Any suitable test system can be used that enables the required accuracy (determined by calibration) and precision (determined by Gauge R&R) to be obtained. The repeatability and reproducibility (Gauge R&R) of the test apparatus shall not exceed 20 % of the allowed tolerance range for any given…
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…
