IEC 60437:2023 specifies the procedure for a radio interference (RI) test carried out in a laboratory on clean and dry insulators at a frequency of 0,5 MHz or 1 MHz or, alternatively, at other frequencies between 0,5 MHz and 2 MHz. This document applies to insulators for use on AC or DC overhead power lines and overhead traction lines with a nominal voltage greater than 1 000 V. This third…

This document specifies a laboratory test method for measuring perceived air quality using human subjects that can be used for assessing the performance of air cleaners removing gas-phase pollutants. The method describes the performance of gas-phase air cleaners with respect to removal of pollutants that can be sensed by human subjects. The method has a reference to sensory tests specified in ISO…

Scope 1.1 This Standard provides minimum requirements for the security of premises from intrusion and infiltration, as well as considerations for secure access and safe egress. 1.2 This Standard provides the criteria for the installation, maintenance, and testing of physical and electronic premises security systems designed to prevent and detect intrusion into the protected premises by…

Scope 1.1 These requirements apply to portable germicidal equipment intended to expose the air and surfaces within an unoccupied area with uncontained ultraviolet (UV) energy. These requirements address equipment intended to remain stationary while in operation, and intended for use by ordinary persons. The equipment may also produce visible light. 1.2 In this Standard, the UV overexposure…

Scope 1.1 These requirements apply to ultraviolet germicidal irradiation (UVGI) equipment and systems intended for installation and use in accordance with the U.S. National Electrical Code (NEC), NFPA 70 and in accordance with the Canadian Electrical Code, Part I (CEC), CSA C22.1. These requirements cover: a) UV Germicidal Equipment – These devices emit uncontained UV energy into the…
