China Testing & Certification International Group Co., Ltd. (CTC, Stock Code 603060) originated from the testing and certification business of China Building Materials Academy in the 1950s. After 70 years of unremitting efforts and persistent pursuit, the company has formed five business categories: detection and testing, certification and evaluation, testing instruments and intelligent manufacturing, measurement and calibration, scientific research and technical services, committed to providing customers with technical services and comprehensive solutions of detection and testing, certification and evaluation, appraisal, consultation, training, and instruments and equipment in fields of quality, environmental protection, green, safety, health, and energy conservation.

The industry of brake assemblies for automobiles in China has continuously upgraded alongside the development of automotive safety technology. In the 1980s and 1990s, with the initial popularization of economy passenger cars and commercial vehicles, brake assemblies entered the stage of mass production. At that time, drum brakes with basic structures, such as cast iron brake drums and asbestos friction linings, were primarily used to meet basic vehicle braking safety needs. Since the turn of the century, the expansion of the passenger car market and the rise of active safety concepts have driven the transformation of brake assemblies towards disc brakes. The integration of ABS (Anti-lock Braking System) and EBD (Electronic Brakeforce Distribution) has become mainstream. The application of aluminum alloy calipers and non-asbestos friction materials has achieved dual improvements in braking responsiveness and lightweight design. In recent years, the rapid development of new energy vehicles (NEVs) has imposed new requirements on brake assemblies, including low drag torque, adaptability to regenerative braking systems, and integration with brake-by-wire technology. Furthermore, the iterative upgrade of standards has accelerated the industry's transformation towards intelligence, high efficiency, and environmental friendliness. Currently, China has become a core global production base for brake assemblies for automobiles, covering all types of vehicles, including fuel-powered passenger cars, commercial vehicles, and NEVs, adapting to the full spectrum from microcars to heavy-duty trucks.
We have established a specialized testing team for brake systems, offering customized testing services for braking performance, durability, system compatibility, and more, based on different powertrain types and vehicle classes. This helps products build a competitive advantage in safety performance and technological innovation.
