Center Certification & Testing International
Project Introduction
The scratch test is one of the commonly used standard methods for testing the bonding strength between the surface film and the base material. Use a material with a hardness greater than the surface film to make a sharp tip to scratch on the surface of the sample or workpiece. Add a load to the scratch head until the film and the substrate are out of contact. At this time, the load is the critical load, and the surface film and the surface film can be calculated. Bonding strength between substrates.
Application range
The scratch test is mainly used to detect and evaluate the anti-shear, scratch, planing, scratch and engraving properties of materials such as anodized materials, rigid organic materials, powder coatings, soft metals, plastics, glass and paint adhesives.

RCM certification is a certification system implemented by Australia and New Zealand to ensure that electrical products comply with local safety, electromagnetic compatibility, and other standards.
FCC ID certification is a mandatory requirement under US law. The Federal Communications Commission (FCC) in the United States strictly regulates issues such as electromagnetic compatibility and radio interference in electronic products. As an electronic communication device, routers are only allowed to be sold and used in the US market if they have obtained FCC ID certification, otherwise they will face legal penalties and market bans.
CE-RED certification is a mandatory requirement for market access in the European Union. According to relevant EU regulations, all wireless devices entering the market must be certified by RED (Wireless Device Directive) to ensure compliance with EU standards.
