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.

SRRC certification is one of the necessary conditions for products to enter the Chinese market for sale. It ensures that the wireless transmission characteristics of the wireless camera comply with national standards, avoiding communication problems caused by radio interference and ensuring the legality and compliance of the product.
FCC certification is a mandatory requirement for wireless device certification in the US market. Through FCC ID certification, wireless microphones can prove their compliance with US radio transmission standards, avoiding market bans or fines for violations. This is particularly important for products that hope to be sold in the US market.
KC certification ensures that products comply with relevant laws, regulations, and safety standards in South Korea, and is a necessary condition for smart door lock products to enter the South Korean market. KC certification covers wireless radio frequency, electromagnetic compatibility, and electromagnetic exposure. Strict testing and evaluation are required to obtain KC certification before products can be legally sold in the Korean market and gain consumer trust.
