4 Principle A test specimen having a specified precut slit is subjected to a tearing force generated by the energy stored in a pendulum of specified dimensions. The energy expended in tearing the specimen is used to calculate the tear resistance of the specimen. 5 Apparatus The test machine shall be of the Elmendorf type…
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…
3 Method E1: Tensile performance3.1 ObjectThis test method applies to optical fibre cables which are tested at a particular tensile strength in order to examine the behaviour of the attenuation and/or the fibre elongation strain as a function of the load on a cable which may occur during installation and operation. This method is intended…

8.4.2 Flexing test8.4.2.1 Apparatus8.4.2.1.1 Testing device, as illustrated in Figure 45. The test piece shall be guided in such a way that on one side it can be bent at an angle of 90° about a mandrel with a radius of 15 mm. 8.4.2.1.2 Cutting tool, as defined in Figure C.2 of ISO 5423:1992.8.4.2.1.3 Measuring…
Methods for characterization of slow crack growth Pipes made of polyethylene such as PE80, PE100 or the improved PE100RC display differing levels of sensitivity to slow crack growth. The terms “Environmental Stress Cracking” (ESC) and “Slow Crack Growth” (SCG) are used to describe this behavior. A failure of this type takes place well below the…
Unpacking The machine will go to the customer with the main machine, anvils, and pendulums as per order. Power cable is also in the pack. Place the machine on very robust table. Power The main power for this model is less than 500W in a single phase. The power cable will come to you that…
Unpacking the machine Basic model of mini desktop injection molding machine comping to the customer with the machine, controller, molds (as per order), power cable. After placement of the machine in a robust table you need to tighten the base plate to the table. According to the type of base plate, this will be done…
