In the global safety standard system for home appliances, IEC 60335 - 1 stands as a crucial international guideline. Developed by the International Electrotechnical Commission (IEC), this standard sets general safety requirements for household and similar electrical appliances. Notably, it plays a vital role in protecting millions of families by ensuring the electrical safety of their daily - used devices. Among its many testing requirements, the scratch resistance test emerges as a key step to safeguard the safety of appliance casings and accessible components. Correspondingly, the IEC60335-1 scratch tester acts as an "authoritative judge" to measure whether products meet these strict standards. Here, the PEGO scratch tester PG-9583 has gained significant recognition in the field due to its excellent performance.

1. The Core Role of IEC 60335 - 1 Standard

IEC60335-1 serves as the cornerstone for ensuring the safety of home appliances. Why is it so important? The answer lies in its deep understanding of real - life usage scenarios. In daily life, appliance casings often face external forces like friction and scratches during transportation or regular contact. If a material lacks sufficient scratch resistance, its surface coating or substrate can easily get damaged. This not only harms the product's appearance but also poses potential risks. For example, when an insulating casing is scratched, metal parts might be exposed, leading to electric leakage. Similarly, for heating appliances, a damaged surface can accelerate material aging and even cause fire hazards. Thus, the standard directly addresses these risks to keep users safe.

2. Why the Scratch Tester Matters

The scratch test plays a pivotal role in product safety. How? It simulates daily scratching to assess a material's ability to resist damage under specific conditions, ensuring the product remains safe throughout its lifecycle. Moreover, passing this test is like a "passport" for market entry, showing enterprises' commitment to consumer safety. This is where the PEGO scratch resistance tester PG-9583 steps in. With its precise testing capabilities, it provides reliable data to verify product compliance, helping companies fulfill their safety promises effectively.

3. How the Scratch Resistance Tester Works

The operation of the scratch tester is both scientific and straightforward. First, it uses a hardened steel pin for scratching. The end of this pin is tapered to a 40° apex angle, and its tip is rounded to a radius of 0.25 mm ± 0.02 mm. During the test, the pin scratches the sample at a speed of 20 mm/s ± 5 mm/s in a plane perpendicular to the conductor's edge. Additionally, a force of 10N ± 0.5N is applied along the pin's axial direction to ensure consistent pressure. To avoid interference, the scratch interval is kept at least 5mm, and each scratch is at least 5mm away from the sample's edge. Furthermore, the tester features a user - friendly PLC and touch screen control system. Its rotating work surface allows easy scratch testing in both directions, making the process efficient and accurate.

4. Wide Applications of the Scratch Resistance Tester

The utility of the IEC60335-1 scratch resistance tester spans the entire lifecycle of home appliance products. In the R&D stage, it helps with material selection; during production, it ensures quality control; and before market access, it verifies compliance. Let's look at specific industries:

Electronics and Communications: It tests components like shells and screens of mobile phones, tablets, and smart watches, which are often made of metal, plastic, or composite materials. The test checks if these products can resist scratches from keys or desktops in daily use. Screen protectors also rely on this device for quality assessment.

Metal and Metal Surface Treatment: It evaluates the scratch resistance of metal surface coatings (such as chromium or zinc plating) and oxide layers. For example, hardware items like faucets and door locks need their surface treatments to pass the test to maintain both aesthetics and rust resistance.

Material R&D and Quality Control: In material research, the tester compares the performance of different formulas and processes, providing data to optimize components (like adding wear - resistant agents). In production, regular sampling ensures mass - produced materials meet standards, preventing unqualified (non - compliant) products from entering the market.

5. Conclusion: A Silent Protector for Safer Homes

Although consumers may never directly interact with the IEC60335-1 scratch tester, it remains an indispensable part of the home appliance safety chain. The PEGO scratch tester PG-9583, with its outstanding performance, plays a key role in ensuring product quality and driving industry progress. By using scientific data to define material limits and standardized processes to maintain quality consistency, it integrates safety and reliability into every home appliance. As safety standards in the home appliance industry continue to evolve, the PEGO PG-9583 will undoubtedly keep innovating, contributing more to creating a safer living environment for families worldwide.
