UN / ECE R6 Tests

UN ECE R6 tests cover a series of tests applied in accordance with the regulation on direction indicators of vehicles in categories L, M, N, O and T.

ECE regulations define cross-border technical regulations for establishing approval or uniform approval procedures for motor vehicles and motor vehicle parts. Automated commercial vehicles are already fully eligible for approval in this respect, but only through appropriate individual measures in the country in which they will be used. What is missing is a set of rules at the international ECE level.

Regulation No. 6 of the United Nations Economic Commission for Europe (UN/ECE) — Covers the uniform provisions for the approval of direction indicators for power-driven vehicles and their trailers, and the tests applied accordingly.

According to UN ECE R6 Regulation, 'Direction indicator' means a device mounted on a motor vehicle or trailer and which, when operated by the driver, signals the driver's intention to change the direction the vehicle is moving in. This Regulation applies only to fixed-position flashing light devices, the flashing of which is produced by intermittent electric current to the lamp.

Devices must be designed and constructed in such a way that they are guaranteed to operate satisfactorily under normal conditions of use and regardless of the vibrations to which they may be subjected, and to maintain the specifications set forth in this regulation.

All measurements will be made photometrically and colorimetrically:

• In the case of a lamp with a replaceable light source, it is supplied with the voltage necessary to produce it, by a colorless or colored standard filament lamp of the category prescribed for the device, unless it is provided by an electronic light source control device or variable intensity control.
• In the case of a lamp equipped with non-replaceable light sources (filament lamps and others), it is tried at 6,75 V, 13,5 V or 28,0 V, respectively.
• In the case of an electronic light source control device or a system using variable intensity control, the voltage declared by the manufacturer at the input terminals of the lamp that is part of the lamp (4), or 6 if not specified, is set to 75 V, 13,5 V or 28,0 V, respectively.
• In the case of an electronic light source control device or a system using variable intensity control, the lamp must not be part of the lamp by applying the manufacturer's declared voltage to its input terminals.
• However, in the case of a category 2b direction indicator operated with a variable intensity control to achieve variable light intensity, photometric measurements will be made according to the applicant's definition.
• The testing laboratory shall request from the manufacturer the light source control gear or variable intensity control necessary to provide the light source and applicable functions.

Direction indicators, tested and approved within the scope of this regulation, are manufactured in accordance with the approved type by providing the conditions specified in paragraphs 6 and 8 of the regulation. For the test to be considered successful, the test results must meet the requirements of the regulation.
