Electrical Appliance Insulation Surface Scratch Resistance PLC Control Test Apparatus
Standards & Clauses:
IEC60335-1:2016“Household and similar electrical appliances-Safety-Part1:General requirements”clause 21.2 IEC60950-1:2013“Information technology equipment-Safety-Part1:General requirement”clause 2.10.8.4
Samples and Restrictions:
Solid insulated parts that have been touched, coated with printed boards or coated components of household and similar appliances
Application:
It is used to check whether accessible parts of solid insulation shall have sufficient strength to prevent penetration by sharp implements.
Structure:
Desktop structure, size: about 600 × 550 × 600 (mm) W × H × D, weight: 60kg
Use Environment:
Power supply:AC220V±10%/50-60Hz or match client's local power supply requirements Working temperature 0-40 ° C, humidity 30%-90%
Technical Parameters:
Test Principle:
The surface of the insulation is scratched by means of a hardened steel pin, the end of which has the form of a cone with an angle of 40 °. Its tip is rounded with a radius of 0.25mm±0.02mm. The pin is held at any angle from 80 ° to 85 ° to the horizontal and loaded so that the force exerted alng its axis is 10N±0.5N. The scratches are made by drawing the pin along the surface of the insulation at a speed of approximately 20 mm/s. Two parallel scratches are made. They are spaced sufficiently apart so that they are not affected by each other, their length covering approximately 25% of the length of the insulation. Two similar scratches are made at 90° to the first pair without crossing them. This apparatus adopts PLC + touch screen control system, and stepping motor. The scratch distance, scratch times and scratch speed can be preset. It is easy to achieve scratch test in both directions by rotating to 90°angle automatically. |
