Norms

Normative references for approval of luminous devices for authorized vehicle

Regulation UN/ECE No. 10 determines the requirements that vehicles and electrical and/or electronic devices (intended to be fitted in these vehicles) should fulfill with regard to electromagnetic compatibility.

Regulation UN/ECE No. 10 applies to vehicles, components or electrical/electronic units (mechanically fastened to the vehicle so that they cannot be removed without use of tools or connected permanently or temporarily to the vehicle wiring harness) with regard to electromagnetic compatibility. Electromagnetic compatibility means the ability of a vehicle or components or separate technical units to function satisfactorily (immunity) in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment (emission).

Luminous warning devices manufactured by Sirena, intended to be used on authorized vehicles, fulfill the requirements of the Regulation UN/ECE No. 10 and have therefore be assigned an approval number. Regulation UN/ECE No. 65 - Uniform provisions concerning the approval of special warning lamps for power-driven vehicles and their trailers.

Regulation UN/ECE No. 65 applies to special warning lamps for powerdriven vehicles and their trailers. “Special warning lamp” means a lamp emitting blue, amber or red light intermittently for use on vehicles. It is possible to distinguish devices among: “Rotating or stationary flashing lamp” means a special warning lamp emitting light intermittently all around its vertical axis (Category T). “Directional flashing lamp” means a special warning lamp emitting light intermittently in a limited angular area (Category X). “Complete bar” means a special warning lamp with two or more optical systems emitting light intermittently all around its vertical axis. Special warning lamp could have one level of intensity (Class 1), or two levels of intensity (Class 2). Regulation UN/ECE No. 65 outlines i.a. specifications that special warning lamps should comply with in order to obtain the approval: - general specifications (vibration and water resistance, frequency, the “ON” and the “OFF” time, operating temperature range, tamperproof..) - photometric specifications (minimum and maximum values of the effective luminous intensity) - colorimetric characteristics of the light emitted through the filter/ covers (blue/amber/red) expressed in chromaticity coordinates.

Luminous warning devices manufactured by Sirena fulfill the requirements of Regulation UN/ECE No. 65. CISPR 25 - Radio disturbance characteristics for the protection of receivers used on board vehicles, boats, and on devices - Limits and methods of measurement.

CISPR 25 is the standard for classification of emitted interference on a scale of 1 - 5. Products in category 3 satisfies the statutory standards which guarantees adequate protection in standard practice. New SIRENA lighting systems satisfy at least category 3, and guarantee absolute functional safety in all application situations.
