適用範囲

This standard specifies the general requirements, indication errors, and test specifications for speed meters for motor vehicles in their installed state. It applies specifically to M and N category vehicles as defined in Chinese automotive classifications. It is mandatory for all relevant manufacturers to ensure compliance with these specifications.

技術要求

The standard outlines the general design and display requirements for automotive speedometers. It mandates that the dial must be located within the driver's direct field of vision and remain clearly readable day and night. The indicated speed range must encompass the maximum speed specified by the vehicle manufacturer. Regarding the scale, the speed unit must be displayed in km/h. For speeds above 20 km/h up to the maximum limit, the graduation value must be one of 1, 2, 5, or 10 km/h. Specific interval display rules apply depending on whether the maximum dial value exceeds 200 km/h, though the intervals do not need to be uniform across the entire dial. The core technical requirement addresses indication errors. The standard strictly specifies that the indicated speed must never be lower than the actual speed. The relationship between the indicated speed and the actual speed must satisfy a specific mathematical formula defined in the document, ensuring the error remains within calculated permissible limits. Manufacturers must ensure their speedometer calibration strictly adheres to this error formula.

試験方法

Testing must be conducted at a reference temperature of 23°C ± 5°C. The test instruments used to measure the vehicle's speed must have an error margin not exceeding ±1.0%. Prior to testing, the vehicle must be in unladen mass condition, and tire pressures must be set to the manufacturer's specified cold inflation pressure plus an additional 0.02 MPa. Road tests must be conducted on flat, dry surfaces with sufficient adhesion, in accordance with the general vehicle road test methods specified in GB/T 12534. The speedometer is evaluated at three specific test speeds: 40 km/h, 80 km/h, and 120 km/h (or 80% of the maximum speed if it is below 150 km/h). Accurate testing under these precise conditions is critical for achieving compliance certification.

よくある質問

What products are regulated under GB 15082-2008?

This standard applies to speed meters installed in M and N category vehicles as defined by Chinese automotive classifications. It regulates the speedometer's performance in its installed vehicle state.

Are there any updates from the previous version of GB 15082-2008?

The 2008 version modifies the general requirements (such as scale intervals and display parameters) and updates the basic error relationship formula to better align with international regulations like ECE R39-2003.

How does GB 15082-2008 differ from international standards?

GB 15082-2008 is technically aligned with the UN Economic Commission for Europe regulation ECE R39-2003 regarding the approval of vehicles for speedometers and their installation. Manufacturers compliant with ECE R39 will find similar technical requirements in this Chinese standard.
