Overview
SIST EN ISO 10650:2026 - Dentistry - Powered polymerization activators (ISO 10650:2026) specifies requirements and test methods for powered polymerization activators designed for chairside use in dental practices. These devices are essential for the polymerization of dental polymer-based materials using light in the 380 nm to 515 nm wavelength region. The standard covers equipment such as quartz-tungsten-halogen lamps and light-emitting diode (LED) lamps, whether powered by internal rechargeable batteries, external mains supply, or dental units. Notably, this standard does not apply to lasers, plasma arc devices, or activators used in laboratory fabrication of indirect restorations, dentures, veneers, and other dental appliances.
Developed by the Slovenian Institute for Standardization (SIST) in alignment with ISO/TC 106/SC 6, this document plays a pivotal role in ensuring the safe, effective, and standardized use of polymerization devices in dental healthcare settings.
