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.

As an emerging contaminant, the potential threat of perchlorate to human health and the ecological environment cannot be ignored. In 2022, the National Health Commission released the "Standards for Drinking Water Quality" (GB 5749-2022), which includes perchlorate as a controlled inorganic pollutant for the first time, setting a limit of 70 μg/L . For adults, continuous intake of perchlorate may induce bone marrow hematopoietic cell dysplasia. For infants and young children, excessive perchlorate intake may lead to serious consequences such as lower IQ, learning disabilities, developmental delays, and attention deficit hyperactivity disorder.
