PV module backplane scratch resistance testing machine/Backboard scratch Testing equipment /cut susceptibility testing machine

 

Testing Standard

It's according to IEC61730-2:2016 testing standard 

 

 

Purpose

To determine whether any front and rear surfaces of the pv module made of polymeric materials are capable of withstanding routine handling during installation and maintenance without exposing personnel to the danger of electric shock

 

Testing standard frame feature

1. The raw materials: Aluminum profile ( Firm and Antirust)

2. The testing standard dimension: satisfy 2.2m×1.3m pv modules ( adjustable, suit for 

    diffferent pv modules dimension)

3.Included the Tracking pulley wheel

 

 

Testing Fixture

1.The raw material:Use adopt carbon steel blade

2.The steel blade thickness:0.64mm±0.05mm ( It’s suffficiently rigid as not to be bend 

   sideways during the test)

3.The top angle of steel blade :90±2° and with rounded with radius 0.115mm±0.025mm

4. The blade supply the force : 8.9N±0.5N

 

 

 

The Mainly Feature

Feature	Use motor constant speed tracking , speed can set,  tracking directing can adjustable
The test fixture speed	150±30mm/s
Control ways and display ways	Touch screen
Electricity	220V 50HZ

 

 

 

Testing procedure

1. Position the PV Module horizontally with the test surface facing upward

2. The test fixture is to be placed on the surface for 1 min and then drawn across the surface of the pv module at a  speed of 150mm/s±30mm/s, repeat the procedure five times in different directions considering the most critical points

3. Repeat step 1 and step 2 for other polymeric surface of the pv module if applicable
