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.

Wireless keyboard TELEC certification is a mandatory certification in Japan for wireless transmission equipment, with the full name being Technical Standards Conformity. This certification is implemented in accordance with Japan\'s Radio Law, aiming to ensure that wireless keyboards and other wireless devices comply with the technical standards and regulatory requirements of the Japanese market.
If a company is planning to export wireless keyboards to Canada, then ISEDIC certification is definitely a key focus you need to pay attention to! ISEDIC certification is a mandatory requirement of Industry Canada for wireless devices, and products that have not been certified will not be able to enter the Canadian market.
The TELEC certification for children\'s watches is a necessary condition for this product to enter the Japanese market. TELEC (Telecom Engineering Center) certification is a mandatory certification for wireless equipment in Japan, aimed at ensuring that the equipment complies with Japanese radio regulations.
