You can conduct tensile tests on different materials with the help of the steps mentioned below: Prepare dumbbell-shaped specimens accurately Begin by taking a strip of the material you intend to test. Ensure that the strip is representative of the material's properties. Place the sample strip onto the dumbbell cutting die. A dumbbell cutting die is a specialized tool designed to shape the specimen into the required dumbbell form. Execute the cutting process according to the specific instructions outlined in the test standard applicable to the material. This ensures uniformity and adherence to testing standards. Starting the machine Plug the machine into a power source with the specified electrical requirements that include 5 amp, 220 Volts AC supply. Ensure that the power source is compatible with the machine's electrical specifications. After connecting the machine to the power source, activate it by turning the machine on. Turning on the machine initialises its electrical systems and prepares it for operation. Placement of testing specimen Upper Grip Placement: Position the upper side of the specimen between the upper fixed grips. Securely tighten the grips to ensure a firm hold on the specimen. Lower Grip Adjustment: Move the lower movable grip upwards to facilitate easy placement of the specimen between the grips. This adjustment ensures that the specimen reaches the grips comfortably, promoting a secure and stable setup. Lower Limit Switch: Verify that the lower limit switch ring is appropriately positioned, maintaining a minimum distance of 25 mm. This distance setting is vital for controlling the testing parameters and ensuring the accuracy of the results. Lower Grip Placement: Insert the lower end of the specimen between the lower grips and securely tighten the grips. Confirm that the specimen is centrally aligned within the grips to maintain uniformity and prevent any biases in the test results. Once the sample is placed you can easily commence the test.

Dart impact test is performed on plastic films and laminates to determine the effect of free falling dart on plastic films. The energy created by the falling dart causes the film to fail under some specified conditions. The test is widely performed by the manufacturers in plastic industries and paper & packaging industries to assess the durability and strength of the plastic films and other related products. To perform the impact test using the Dart Impact Tester, first of all, the user need to prepare the test sample as per the standards for precise and reliable results. This includes certain steps. Preparation of Test Specimen As per the Standards ASTM - D 1709 - 15a, ASTM - D 3029 - 82a, IS - 2508 - 1984, to prepare the specimen to perform the Dart Impact Test efficiently using Dart tester, you need to follow certain steps: Measure the thickness of the test sample in the area of the impact to the nearest 0.002mm. Take at least five measurements with the help of a suitable thickness gauge. Find the means of all the five values and record the thickness of the sample easily. Test Specimen need to be large enough to extend beyond the specimen clamping ring by at least 25mm at all the points. The specimens must be the representative of the film under study and shall be taken from the sheet or tube in such a manner, so that whole of the sheet is represented in the test. The specimen needs to be clamped by the specimen holder ring. Do not forget to connect 6mm pneumatic pipe from the vacuum pump. Power ON the vacuum pump so that the sample will be held due to a vacuum pump and it will be ready for testing. Points to be considered before implementing the Test Procedure Check whether you have adjusted the level of the machine with the spirit level or not. Lock the leveling bolts in the perfect position and ensure that the apparatus does not vibrate. Do not forget to connect the power supply cord of the device to a 3 pin 5-ampere socket on a single phase 230V AC supply line. Ensure the proper earthing connection of the socket outlet. Ensure the location of the release mechanism of the vertical channel support. The dropping height of the dart of 660mmcan be attained by fixing the drop height in the middle set of holes. To set the height of dart at 1524mm, fix it in the upper most holes Note: If the release mechanism is not fixed in the desired position, simply remove it from the present position and reaffix it at the desired one. SOP – Dart Impact Test on Plastic Films As per provided ASTM and IS standards, after choosing appropriate sample and after adjusting the height of the drop as per the standards and application requirement, Select appropriate weight of the dart, which is nearest to the expected impact failure weight. You can also add required number of incremental weights to the dart shaft and put the locking collar in its place in order to set the weights in a particular location. Place the first test sample from the top of the clamp ensuring that it is uniformly flat and wrinkle free and overlaps the clamp by about 25mm on all sides. Hold the sample firmly. Put on the vacuum pump to adjust the sample to get stretched and for the wrinkle free and fold free sample. After the sample is held firmly in the clamp, place the upper tip of dart in the center hole of the electromagnet and keep it pressed in an upward direction. How to take the exact reading of the Scale? To perform the test, fix the electromagnet clamp / holder at different length of 660mm & 1524mm with the given formula: Scale Length + Dart Length + Electro Magnet length = Reading of Scale For example: If the length of scale is 660, 660mm + 212mm + 35mm = 907mm If the length of the scale is 1524mm, 1524mm + 226mm + 35mm = 1785mm Now press the push button on the side of the channel to activate the electromagnet. Now release the push button to enable the dart to fall on the centre of the specimen which is held in the clamp. Examine the test sample to determine whether it has failed or not. If the sample failed, reduce down the weight and if not failed, then take fresh test sample to perform the test with the enhanced weight. Repeat the process until the sample fails at least 50%. Formula to Calculate the Impact Resistance Impact Resistance = M100 – D (S1/100 – 0.5) Where, M100 = lowest weight according to the D used at which 100% failure occurs. D = Uniform increment weight used (in grams) S1 = Result (Percentage Failure) – Sum of Percentage of breaks at each weight. For example, Weight No. of Test Samples Taken Result (Percentage Failure) Number of Samples Broken 90 10 0 0 105 10 10 1 120 10 20 2 135 10 60 6 150 10 100 10 = 190 Impact Resistance = 150 -15(190/100 – 0.5) = 129 grams Where, D = 15 (uniform incremental weight) If you are looking for Dart Impact Tester Price then you can consult with us.
