Scratch tool scratch test probe complies with GB4706.13 Figure 102 standard.

Complies with standards such as IEC 60335-2-24 Figure 102 and GB 4706.13 Figure 102, used for scratch testing on all accessible component surfaces of protected cooling systems in household appliances, including accessible surfaces in close contact with protected cooling systems. For example, scratch resistance testing of refrigerator doors.

Product material: Hard brazed hard gold sheet K10

Related product introduction:

Scratch resistance testing is a simulated safety test item specified in standards such as IEC 60950-1:2001, BS EN 60950-1:2001, GB 4943-2001 "Safety of Information Technology Equipment," and IEC 60065:1998, GB 8898-2001 "Safety Requirements for Audio, Video, and Similar Electronic Equipment."

The scratch resistance tester applies a test force of 10N along the axis of a steel needle with a specified shape and a 40° conical tip under standard conditions. It performs unidirectional scratches at a certain scratch speed of 20mm/s and a specific tilt angle of 80°–85° on the horizontally placed printed circuit board sample multiple times. The scratch resistance of the printed circuit board is evaluated based on whether the coating loosens, penetrates, and withstands the specified dielectric strength test. The scratch resistance tester is suitable for research, production, and quality inspection departments of products and components such as lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical appliances, motors, power tools, electronic instruments, electrical instruments, information technology equipment, and audio-video equipment. It is also applicable to the insulation materials and printed circuit board industries.
