GB/T1843-2008 Test Method for Determination of Impact Strength of Plastic Cantilever Beams
This scheme applies to the following range of materials:
Hard thermoplastic molding and extrusion materials, including filler materials and reinforced unfilled materials, rigid thermoplastic sheet;
Hard thermosetting molding materials, including filled and reinforced materials, hard thermosetting sheets, including laminates;
Fiber-reinforced thermosetting and thermoplastic composites, including unidirectional or non-unidirectional reinforcements such as felts, fabrics, textile rovings, staple tow, composite and hybrid composites, glass rovings and broken fibers, and prepreg materials Sheet (prepreg);
Thermotropic liquid crystal polymer.
This solution is generally not suitable for hard porous materials and sandwich materials containing porous materials. In addition, long fiber reinforced composites or thermotropic liquid crystal polymers generally do not use notched specimens.
This program is mainly applied to the plastic products enterprises to carry out plastic incoming materials and product quality inspections. The plan includes the objectives of impact tests, relevant test standards, sample types, and typical test equipment for application and test applications.
1, the impact of the test target
Plastics are used to measure the impact strength of cantilever beams under specified conditions to detect the basic impact mechanical properties of plastic materials.
The characteristic parameters are:
Unnotched Izod Impact Strength: The impact energy absorbed when an unnotched specimen breaks. It is related to the original cross-sectional area of ​​the specimen and is expressed in KJ/m2.
Notched Izod impact strength: The impact energy absorbed when a notched specimen breaks is related to the original cross-sectional area at the specimen notch and is expressed in KJ/m2.

4. Typical test equipment for test applications:
4.1 Test Equipment
Test Equipment Standard Configuration: Host + Accessories
The mainframe is equipped with cantilever pendulums with different impact energies to meet the material testing requirements for different impact strengths.
Host: PTM1000 Series Sansi Plastic Pendulum Impact Tester
PTM1000 Series
The machine adopts semi-automatic control, simple operation and high work efficiency. Test data is automatically obtained after impacting the sample. The test chambers and manufacturers that continuously perform impact tests and do a lot of impact tests can better reflect their superiority.
PTM1000 Series LCD Display
Energy display using LMC LCD screen, no need to read data from the dial, no data error, high accuracy and high efficiency.
PTM1000 Series Hanging Pendulum Device
Simple and reliable structure, easy operation
annex:
Cantilever beam to choose from: a model: 2.75J, 4J, a model: 5.5J, 11J, 22J
