T110 hundred grid scratch tester Operation

　　T110 hundred grid scratch tester Benchmark Instrument Erichsen430P is used to test the scratch resistance and scratch performance of automotive plastic interior and exterior parts.It is a testing equipment independently developed and produced by our company Shanghai Qianshi Precision Electromechanical Technology Co.,Ltd

　　Applicable standards:

　　PV3952,PV3974 Volkswagen Standard,GMW14688 General Motors Standard,VDA621-411 Paint Adhesion,EN ISO 2409 Coatings-Grid Cut Test for Coatings,ASTM D3359 Standard Test Criteria for Coating Adhesion by Tape Method

　　Operation:

　　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 and rotate the testing fixture horizontally by 90 degrees;

　　10.Set parameters such as speed,number of grids,spacing,and stroke again,and perform scraping motion between the scraping head and the material surface;

　　11.Automatically stop when the set value is reached,remove the sample for observation;

　　12.Turn off the instrument and the test is completed;

　　13.After the instrument test is completed,take the sample for analysis and comparison,evaluate the sensory level of scratches after scraping,the color difference changes in the scraped and non scraped areas,or the detachment of the surface coating of the sample after scraping and adhesive tape treatment.
