Measurement procedure. The frequency characteristics of the sound shall be measured together with an input signal to the external sound generation system corresponding to the reference vehicle speed. The sound output of the system shall be measured as follows: Record at least 5 seconds of the sound at a constant vehicle speed. Using a ▇▇▇▇▇▇▇ window, calculate the autopower of the signal with a frequency resolution of at least 1 Hz using at least 66.6% overlapp averages from the 5 second time signal The frequencies, fi, speed, of the external sound generation system signal shall be measured and recorded. The corresponding vehicle speeds, fi,speed and fi,ref shall be measured and recorded. Calculate del_f, the frequency shift of the external sound generation system signal according to equation (1): del_f = {[(fi,speed - fi,ref)/(vtest – vref)]/fi,ref} · 100 (1) where fi,speed is the frequency at a given speed value; fi,ref is the frequency at the reference speed value; vtest is the vehicle velocity, actual or simulated, corresponding to the frequency fi,speed; vref is the vehicle velocity, actual or simulated, corresponding to the frequency fi,ref; This equation is only valid when the actual vehicle speed, vtest, is higher than the reference vehicle speed, vref. Results shall be reported using Table 3. Table 0A3 — Vehicle speed for measurement to determine frequency shift Target speed Actual Speed (km/h) Frequency, fi, speed (Hz) Frequency Shift Reference vehicle speed Not Applicable 10 km/h 15 km/h 20 km/h NOTE The reference speed should be 5 km/h unless other speeds are desired. ISO comment : If we are going to choose the reference speed as 5, need to change sentence: " The reference speed shall be 5 km/h Figure 1a and 1b

Measurement procedure. Measurement of the battery current shall start at the same time as the test starts and shall end immediately after the vehicle has driven the complete driving cycle.

Measurement procedure. 3.1. Measurement of the battery current shall start at the same time as the test starts and shall end immediately after the vehicle has driven the complete driving cycle. 3.2. Separate values of Q shall be logged over the Part One and Part Two of the cycle." METHOD OF MEASURING THE ELECTRIC RANGE OF VEHICLES POWERED BY AN ELECTRIC POWER TRAIN ONLY OR BY A HYBRID ELECTRIC POWER TRAIN AND THE OVC RANGE OF VEHICLES POWERED BY A HYBRID ELECTRIC POWERTRAIN 1. MEASUREMENT OF THE ELECTRIC RANGE The test method described hereafter permits to measure the electric range, expressed in km, of vehicles powered by an electric power train only or the electric range and OVC range of vehicles powered by a hybrid electric power train with off-vehicle charging (OVC-HEV as defined in paragraph 2. of Annex 8). 2. PARAMETERS, UNITS AND ACCURACY OF MEASUREMENTS Parameters, units and accuracy of measurements shall be as follows: Parameter Unit Accuracy Resolution Time s +/- 0.1 s 0.1 s Distance m +/- 0.1 per cent 1 m Temperature degrees C +/- 1 degree C 1 degree C Speed km/h +/- 1 per cent 0.2 km/h Mass kg +/- 0.5 per cent 1 kg Electricity balance Ah +/- 0.5 per cent 0.3 per cent 3. TEST CONDITIONS 3.1. Condition of the vehicle 3.1.1. The vehicle tyres shall be inflated to the pressure specified by the vehicle manufacturer when the tyres are at the ambient temperature. 3.1.2. The viscosity of the oils for the mechanical moving parts shall conform to the specifications of the vehicle manufacturer. 3.1.3. The lighting and light-signalling and auxiliary devices shall be off, except those required for testing and usual daytime operation of the vehicle. 3.1.4. All energy storage systems available for other than traction purposes (electric, hydraulic, pneumatic, etc.) shall be charged up to their maximum level specified by the manufacturer. 3.1.5. If the batteries are operated above the ambient temperature, the operator shall follow the procedure recommended by the vehicle manufacturer in order to keep the temperature of the battery in the normal operating range. The manufacturer's agent shall be in a position to attest that the thermal management system of the battery is neither disabled nor reduced. 3.1.6. The vehicle must have undergone at least 300 km during the seven days before the test with those batteries that are installed in the test vehicle. 3.2. Climatic conditions For testing performed outdoors, the ambient temperature shall be between 5 °C and 32 °C. The indoors testing s...

Measurement procedure. (a) Locate a 35 mm or larger format still camera, video camera, or digital equivalent such that the centre of the camera's image plane is located at Mr and the camera lens is directed at the centre of the display's rear- view image. (b) Affix a ruler at the base of the rear-view image in an orientation perpendicular with a test object cylinder centreline. If the vehicle head restraints obstruct the camera's view of the display, they may be adjusted or removed. (c) Photograph the image of the visual display with the ruler included in the frame and the rear-view image displayed.

Measurement procedure. To measure time, an ordinary stopwatch and timing to a resolution of one second is sufficient. all power fig- ures are to be recorded in ▇▇▇▇▇ (W). Table 38 outlines the steps of the OM test procedure. Service/maintenance modes (including colour calibration) generally should not be included in measurements. any adaptation of the procedure needed to exclude such modes that occur during the test shall be noted. as stated above, all power measurements are to be made in accordance with IEC 62301. Depending on the nature of the mode, IEC 62301 provides for instantaneous power measurements, five-minute accumulated energy measurements, or accumulated energy measurements over periods long enough to properly assess cyclical con- sumption patterns. Regardless of the method, only power values should be reported.

Measurement procedure. True RMS power measurements will be taken at the panel that energizes the circuit containing only the sampled fixtures.

Measurement procedure. In choosing a representative cross section for velocity measurements, the following characteristics are sought: a relatively straight length of channel approximately 300’ long with a suitable measurement section approximately in the middle, or slightly downstream of the middle, a channel clear of vegetative matter and other obstructions such as large rocks, the flow should not have eddies or dead zones, avoid converging or diverging flow areas. When a suitable measurement site has been chosen the following procedure is used to obtain the velocity readings used to create a velocity profile. Measurements will be made using the USGS standard mid-section method. This method involves measuring the channel cross sectional area and water velocity at multiple cells across the channel.

Measurement procedure. The measurement of temperature is done concurrently with the other parameters being measured by the ProPlus Handheld Multiparameter Instrument. Every attempt is made to take these measurements in a representative section of the stream. The following procedure is used:

Measurement procedure. The solar heat gain profiler will be placed across different areas of the measurement sample and 10-second averages will be taken. The results will be documented using photographs.
