standard environment
, and special treatment required by the test materials and product standards;12. Types;
13. A single test result, as shown below:
(1) Grouping according to three destruction types:
C is completely destroyed, including hinge damage H;
P is broken
N without damage -no damage occurs.
(1) Select the type of damage that occurs as many times, and record the average value of this damage type impact intensity X, and use the letter C or P to record the corresponding destruction type;
(3) If there is a lot of destruction types N, only record letters n;(4) Destroy the type, add letters C, P, or N between the two brands, only when the number of times appears is higher than 1/3 (otherwise an * number is inserted).
14. If necessary, the average standard deviation;
15. Test date.
The use of cantilever beam impact test machines:
The cantilever arm beam impact test machine Also known as a hammer impact test machine is mainly used for hard plastic (including plates, pipes, plastic heterogeneous materials), enhanced nylon, glass fiber reinforced fiber reinforcement The determination of the impact toughness of non -metallic materials such as ceramics, cast stones, and electrical insulation materials is an ideal test equipment used by the chemical industry, scientific research units, and 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.
