Manufacturer:IEC 60335 Abrasion Resistance Tester is used to check abrasion strength of printed circuit boards or the insulating accessible parts of the household appliances. It conforms to the standard requirement of IEC 60335-1 clause 21.2 and IEC 60950 clause 2.10.8.4.
Product Description:

IEC 60335-1 Clause 21.2 Scratched Surface Resistance Test Apparatus | Abrasion Resistance Tester

Model: BND-DH-21


Overview

Welcome to our product page for the IEC 60335-1 Clause 21.2 Scratched Surface Resistance Test Apparatus, also known as the Abrasion Resistance Tester. Our advanced testing equipment is designed to measure the abrasion strength of printed circuit boards and the insulating accessible parts of household appliances, ensuring compliance with international safety standards.


Compliance Standards

Our Abrasion Resistance Tester adheres to the following standards:

  • IEC 60335-1 Clause 21.2
  • IEC 60950 Clause 2.10.8.4

These standards ensure that the device provides accurate and reliable results in testing the durability and safety of insulation materials.

Scratching pin

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 0,25 mm ± 0,02 mm

Scratching angle

80° ~ 85° to the horizontal and loaded



Testing Procedure

The testing procedure for our Abrasion Resistance Tester is as follows:

1. The insulation is heated to the temperature measured during Clause 11 tests.
2. A hardened steel pin, shaped like a cone with a rounded tip (radius: 0.25 mm ±0.02 mm), is used to scratch the surface.
3. The pin is held at an angle between 80° and 85° to the horizontal and loaded with a force of 10N ±0.5N.
4. Two parallel scratches are made at a speed of approximately 20 mm/s, covering about 25% of the insulation length.
5. Two additional scratches are made at a right angle (90°) to the first pair without crossing them.
6. The test fingernail (Figure 7) is then applied with a force of approximately 10N to check for further damage.
7. The insulation should withstand this test without any additional damage or separation.
8. Finally, a hardened steel pin is applied perpendicularly with a force of 30N ±0.5N to an unscratched part of the surface, followed by an electric strength test as per Clause 16.3.

Why Choose Our Product?

Choosing our Abrasion Resistance Tester ensures that you are using equipment that meets international standards for safety and reliability:

1. Precision Control: Our PLC + touch screen control system allows for precise adjustments and monitoring.
2. Versatility: Adjustable scratching speed, pressure, and distance provide flexibility for various testing needs.
