JL tensile impact testing machine
A product introduction
It is mainly used to measure the energy required for the fracture of plastic samples at the prescribed tensile impact velocity.
Used to measure the brittleness and toughness of nonmetallic materials such as plastics.
Second, the characteristics of
Using the round grating measuring Angle technology, it has the characteristics of high precision, good stability and wide range of measurement
It has the function of calculating the punching power, the impact strength and the average of a batch of samples
It is convenient to check the Angle of elevation and lift Angle
4 display mode: LCD
Three meets the standard:
Test methods of plastic stretch impact performance
ASTM d1822-2006 "test method for the tensile impact energy required to fracture the plastic and electrical insulating materials"
ISO 8256-2004 plastics - stretch - impact strength measurement
Technical parameters:
1 impact velocity: 3.8m/s
2 impact energy: 15J 25J
3 pendulum moment: pd15J=8.03848Nm pd25J=13.39746Nm
4 pendulum early Yang Angle: 160 °
5 striking center distance: 395mm
6 use temperature: 15 to 35 ℃
Sample size: length 80 + + 2mm width 15 plus or minus 0.5mm thickness <4mm
Free length between clamps: 30 + 2mm
9 power supply: 220VAC-15% ~ 220VAC+10% 50HZ (single-phase three-wire system)
10 sample shape and size: 1mm for sample thickness.
The sample made by the product shall retain the original thickness;
The specimen with thickness of more than 4mm shall be machined to 4mm.
For thin films, you can use multi-layer samples, but they should be well overlapped.
11. Select the appropriate pendulum to make the impact energy reading within the range of the test machine, and refer to the following table:
(try to choose a small "t-head" with a small quality when you can clamp the sample)
Pendulum impact energy J t - head mass g
15.0
25.0 to 30 + 1 or 60 + 1
60 + / - 1 or 120 + 1
