Our services cover the testing of VOC emissions and emission rates for materials, components, and finished electronic and electrical products. This helps make products more environmentally friendly and assists enterprises in advancing toward green manufacturing. Key testing parameters include the target VOC emission levels and rates for finished products, the emission levels and rates for TVOC (Total Volatile Organic Compounds), as well as the target VOC emission rates and TVOC emission rates for materials and components.

Service Background

With the increasing level of digitalization, a vast array of electronic and electrical products are now widely utilized in both office and residential environments. The manufacturing of these products involves the use of various materials—such as plastics and paints—that contain Volatile Organic Compounds (VOCs). Ensuring a healthy indoor environment and controlling the VOC emissions from electronic and electrical products is a critical step in addressing environmental hazards at the source. CTI, holding both CMA and CNAS accreditations, offers testing services in accordance with standards GB/T 37840-2019 and GB/T 37757-2019. These services focus on determining the VOC emission levels and rates of components and materials used in electronic and electrical products, thereby assisting enterprises in resolving environmental pollution issues at the source and advancing toward the production of "green" products.
