Electric cross scratch tester parameters
The electric cross scratch tester is used to test the scratch and scratch
resistance of plastic parts inside and outside of automobiles.
Technical parameters:
Instrument power supply: 115/230VAC, 50/60Hz (please specify voltage when
ordering)
Equipment power: 400W
Test piece specification: 80 × 50mm
Sample thickness: 0.5-20mm
Standard load range: 2-50N (2N carry)
Special load range: 1-10N (rounded to 1N) (must be matched with optional
accessories)
Scribed path: 25 or 40mm
Scratching speed: 1m/min or 40mm/s
Applicable standards:
PV 3952, PV 3974, GMW 14688, VDA621-411, EN ISO 2409, ASTM D3359
Operation steps:
1.Firstly, prepare the accessories and test samples;
2.Place the test sample into the fixture and tighten it to secure it;
3.Install the scraping head at the bottom of the guide rod, tighten and fix
it;
4.Install the weight on the top of the guide rod, tighten and fix it;
5.Turn on the switch to enter the LCD screen operation interface;
6.Set parameters such as speed, number of grids, spacing, and stroke;
7.Guide rail transmission, scraping head and material surface for scraping
movement;
8.When the set value is reached, the second stage dialog box will
automatically pop up;
9.Remove the screws on both sides;
10.Rotate the test fixture horizontally by 90 degrees;
11.Reset parameters such as speed, number of grids, spacing, and
stroke;
12.Scratching movement between the scraping head and the material
surface;
13.Automatically stop when the set value is reached, remove the sample for
observation;
14.Turn off the instrument and the test is completed;
15.Remove the sample for analysis and comparison, evaluate the sensory
level of scratches after scratching, the color difference changes in the
scratched and non scratched areas, or the detachment of the surface coating of
the sample after being scraped and treated with adhesive tape.
