What is ISO 15727 about?
ISO 15727 is about UV-C devices used for disinfection. ISO 15727 specifies the measurement of the output of a UV-C lamp, types of UV-C lamp, lamp ballast, and safety issues. ISO 15727 is applicable to the output measurement of linear UV-C disinfection lamps.
ISO 15727 specifies a measurement method for evaluating the output power of UV-C lamps installed in heating, ventilation and air conditioning (HVAC) systems. The method includes the simulation measurement of the UV-C output power of UV-C lamps under various temperatures and various air velocities, and under conditions that the axial direction of the lamp is parallel or perpendicular to the airflow direction.
Who is ISO 15727 for?
ISO 15727 on measurement of the output of a UV-C lamp is useful for:
- Manufacturers of UV-C devices
- Quality control personnel
- Maintenance and installation personnel
- Facility managers
Why should you use ISO 15727?
Clinical medical evidence suggests that various diseases, such as heart disease, neurasthenia, memory decline and influenza, correlate with polluted indoor air. The improvement of indoor air quality is desperately needed. Ultraviolet air disinfection devices are invented in such circumstances. UVC radiation is a known disinfectant for air, water, and nonporous surfaces.
ISO 15727 can reliably evaluate and compare the UV-C output power of UV-C lamps in the ultraviolet germicidal irradiation (UVGI) device based on the testing results. ISO 15727 provides you with two methods to measure the output of a UV-C lamp:
- Measurement of the output of a UV-C lamp in a darkroom: Tests in the laboratory (also known as static darkroom test) are conducted to ensure the accuracy and consistency of the measured results
- Measurement of the output of a UV-C lamp in a test chamber: For industrial application, the tests in a test chamber shall take account of the impact of environmental changes in the field (such as temperature change and air velocity change)
With these measurement methods, ISO 15727 helps you to evaluate the effectiveness of your UV-C lamps.
