3.1 Standard Conditions
Speed-Measuring Device Performance Specifications: Lidar Module
Section 3 - Test Conditions
Allow all measurement equipment to warm up until the system is stable enough to
perform the measurement. Unless otherwise specified, perform all measurements
under standard test conditions as follows:
3.1.1 Standard Temperature. Standard ambient temperature shall be between 20 ºC
(68 ºF) and 30 ºC (86 ºF).
3.1.2 Standard Relative Humidity. Standard relative humidity shall be between 10 %
and 85 %.
3.1.3 Standard Supply Voltage. For a device intended to operate from a nominal 12 V
automotive system, the standard supply voltage shall be 13.6 V ± 0.1 V. For devices
utilizing a battery pack, the standard supply voltage shall be a value specified by the
manufacturer. A well-filtered electronic power supply capable of a voltage adjustment of
±25 % from the nominal should be used for laboratory testing and is recommended for
other tests in place of the battery for safety and convenience. The standard supply
voltage shall be applied to the input terminals of the dc supply cables (including all
connectors and circuit protectors) as furnished by the manufacturer. Adjust the power
supply to within 1 % of the specified standard voltage.
3.1.4 Special Instructions. Each time a test method requires that the lidar device
interact with the target speed simulator, the lidar device shall also be connected to the
standard supply voltage source and its optics properly coupled to the simulator.
