The Scratch Resistance Testing Instrument is a precision device designed to evaluate the scratch resistance of solid insulation components, printed circuit boards, and other accessible parts in household appliances and similar products. The instrument ensures that tested materials possess sufficient mechanical strength and surface durability to resist penetration or damage by sharp objects. It provides reproducible, quantitative, and reliable data for product development, quality control, and safety verification.

Application

The Scratch Resistance Testing Instrument is widely used for:

Scratch testing on solid insulation components of household appliances

Evaluation of printed circuit boards (PCBs) and accessible parts for mechanical durability

Testing enclosures and surfaces for resistance against sharp tools

Comparative assessment of material formulations and surface treatments

Specific testing product: Scratch Resistance Testing Instrument

Standards

The instrument complies with key international and national safety and mechanical standards:

GB 4943.1‑2011 – Information technology equipment – Safety, Part 1 (Clause 2.10.6.6: mechanical strength, drop, impact)

GB 4706.1‑2014 – Household and similar electrical appliances – Safety, Part 1 (Clause 21.2: mechanical strength, scratch resistance of enclosures)

IEC 60950‑1 – Information technology equipment – Safety, Part 1 (Clause 2.10.6.6: mechanical strength, drop, impact)

IEC 60335‑1 – Household and similar electrical appliances – Safety, Part 1 (Clause 21.2: mechanical strength, scratch resistance of enclosures)
