This test method is applicable to Plastic deflection shock damage The measurement of the standardized swinging in the standardized instrument was used to make a sterilization, so that the standard sample was broken, and the energy absorbed by the sample was used. express. The standard test of this test method requires the sample to have a gap for milling. In the test method A, C, and D, the intensity concentration at the gap leads to crispy rather than tough breaks. In the test method E, the impact strength can be obtained by fixing the gap in the desktop 180 ° in reverse. All test results are reported according to the energy absorbed by the width of each unit or the area of the incision.
According to one of the types of the following four code, record the damaged type of each sample:
C completely broken -trial Divide into two or multiple breaks.H hinge breaks -is an incomplete break, part of the sample cannot support itself at the level, and the other part is still vertical (two parts angle between the two parts between the two parts between the two parts? Less than 90 °). (Two sections of the rupture sample are only connected by thin epidermis, and this hinge has no residual rigidity.)
part of the porn , But it does not conform to the definition of the twisted chain, but at least 90%of the cracks between the tip of the dealer and the other side.
NB non -broken -is an incomplete break, and the crack expansion between the tip of the dealer and the other side does not reach 90%. (Just bending, there may be stress whitening phenomenon)
For tough materials, the hammer may not have enough energy to completely break the powerful fiber and
Throw the broken sample block (one or a few pieces). The results obtained from continuous cracking samples should be considered to be dependent on standards and should not be recorded as standard results. For any two materials that have different types of damage (see the definition of code in the method), their impact value cannot be used directly for comparison. Similarly, the average value of the report must be obtained from only a single damage type. This letter code will be labeled behind the impact value of the report to learn from the damage type related to the report value. If a sample is not only one of the types of damage observed, then the average impact value of each damaged type should be indicated in the report, and then the sample percentage of the sample damaged in this way is marked in this way, and attached to it, and attach it. Letter code. 
The use of cantilever beam impact test machines:
The cantilever arm beam impact test machine is also known as the swing Hammer impact test machine is mainly used for hard plastic (including plate materials, pipes, plastic heterogeneous materials), enhanced the measurement of non -metallic materials such as nylon, glass reinforced reinforced, ceramics, cast stone, and electrical insulation materials. The ideal test equipment used by colleges and universities for material performance testing.
Characteristics of cantilever shock test machine Features: The main technical parameters of the cantilever arm beam impact test machine are completely in line with ISO180, IOS2611, JB/T8761 , ASTM D256 and other standards. Touch screen control, simple structure, convenient operation, accurate data, and miniature printing are several major features of this test machine.
