A flammability tester is a device that measures the resistance of materials and products to ignition and combustion under controlled conditions. Flammability testers are widely used in industries where fire safety is a critical factor, such as textiles, plastics, electronics, automotive, aerospace, and construction. Flammability tester can help manufacturers, regulators, and consumers assess the fire hazards and risks associated with different materials and products, and ensure compliance with relevant standards and regulations.

An edge crush tester is a testing instrument that measures the edge-wise compression strength of paper and paperboard materials, such as corrugated board, cardboard, and solid fiberboard. It is used to evaluate the quality and performance of packaging materials in various industries. An edge crush tester Chart consists of a clamp, a load cell, a display, and a controller. The clamp holds the specimen securely and applies a compressive force along one edge. The load cell records the force applied to the specimen, and the display shows the edge crush strength, which is calculated from the force and the width of the specimen. The controller allows the user to set the desired speed, angle, and direction of the compression.

A torque tester is a testing instrument that measures the force required to open or close a plastic bottle cap or other similar closure. It is used to evaluate the quality and performance of plastic products in the packaging industry. A torque tester consists of a clamp, a load cell, a display, and a controller. The clamp holds the bottle or the cap securely and rotates it at a controlled speed and angle. The load cell records the force applied to the bottle or the cap during the rotation. The display shows the torque value, which is calculated from the force and the distance from the axis of rotation. The controller allows the user to set the desired speed, angle, and direction of rotation.

A polariscope is a testing instrument that is used to detect defects and stresses in PET preforms, which are the raw materials for making PET bottles and containers. PET preforms are transparent plastic tubes that are heated and blown into various shapes and sizes. However, during the manufacturing process, PET preforms may develop internal strains or deformities that can affect the quality and performance of the final products. A polariscope works by using two polarized lenses and a light source to examine the PET preforms.

The polarized lenses filter the light and create a dark background. When a PET preform is placed between the lenses, any defect or stress in the material will refract the light and create a colorful pattern. By observing the pattern, the user can identify the type and location of the defect or stress in the PET preform. A polariscope can also measure the angle and intensity of the birefringence, which is the difference in the refractive index of the material along different directions.

A hot air oven is a laboratory instrument that uses dry heat to sterilize equipment and supplies. It is widely used in various industries, such as microbiology, pharmaceutical, and chemical. A hot air oven consists of a double-walled chamber, a heating element, a fan, a thermostat, and a controller. The chamber is insulated with glass wool to prevent heat loss and ensure uniform temperature distribution.

The heating element is located at the bottom or the sides of the chamber and provides the required heat for sterilization. The fan circulates the hot air inside the chamber and maintains a constant temperature. The thermostat regulates the temperature and prevents overheating. The controller allows the user to set the desired temperature and time for sterilization.

A dart impact test is a method to measure the impact resistance of plastic films and laminates by dropping a dart on them from a certain height. The test can help evaluate the quality, durability, and performance of various plastic products and materials. The test can also help compare the effectiveness of different surface treatments, such as electroplating, galvanizing, painting, etc. The test is standardized by several national and international standards, such as ASTM B117, ISO 9227, JIS Z 2371, and ASTM G85.

To perform a dart impact test on plastic films, you will need a dart impact tester, a sample holder, a scale, a release mechanism, and a sample of the material to be tested. You can find some examples of dart impact tester online, such as Presto Group or Amazon. You can also compare the prices, features, and specifications of different models and brands and choose the one that suits your needs and budget.

Here are some steps that you can follow to perform a dart impact test on plastic films:

1. Prepare the sample of the material to be tested according to the standards and specifications. The sample should be large enough to extend beyond the sample holder by at least 25 mm at all points. The sample should also be representative of the material under study and should be taken from the sheet or tube in such a manner that the whole of the sheet is represented in the test. You can use a template to guide the cutting of the sample and a thickness gauge to measure the thickness of the sample.

2. Clamp the sample in the sample holder and connect the pneumatic pipe to the vacuum pump. Turn on the vacuum pump to hold the sample securely and prevent any air pockets. The sample should be clamped by the specimen holder ring and should have a slit that allows the dart to pass through and tear the sample.

3. Adjust the level of the machine with the spirit level and lock the leveling bolts in the proper position. Ensure that the apparatus does not vibrate and has a proper earthing connection. Connect the power supply cord of the device to a 3-pin 5-ampere socket on a single-phase 230 V AC supply line.

4. Choose the appropriate weight of the dart that is nearest to the expected impact failure weight. You can also add the required number of incremental weights to the dart shaft and put the locking collar in its place to set the weights in a particular location.

5. Adjust the height of the drop of the dart according to the standards and application requirements. You can use the release mechanism of the vertical channel support to set the height of the drop. The dropping height of the dart can be 660 mm or 1524 mm, depending on the type of test.

6. Place the dart in the release mechanism and align it with the center of the sample. Make sure that the dart is free from any dirt or dust and has a smooth surface.

7. Release the dart from the starting position by using the trigger or the button of the release mechanism. The dart will fall freely and hit the sample, causing it to tear. The force and the distance of the tear will be recorded by the scale and the display of the device.

8. Remove the sample from the sample holder and examine the damage caused by the dart. You can use a marker to record the maximum force reached by the pointer and the scale. You can also use a ruler to measure the length of the tear.

9. Calculate the Falling dart impact tester of the material by using the formula: Dart impact strength = Weight of the dart in grams / 10 min. You can also use a computer interface or software to generate graphical and numerical reports of the test results.

10. Repeat the test with different samples and weights of the dart to obtain an average value of the dart impact strength of the material.
