Introduction
National Standard of the People's Republic of China GB/T 19129—2015
In-depth interpretation of the performance requirements and test methods for electric horns of three-wheeled vehicles and low-speed trucks
Background of standard revision and analysis of technical evolution
GB/T 19129—2015 is a comprehensive revision of GB/T 19129—2003, which mainly optimizes and upgrades the performance requirements and test methods for electric horns of three-wheeled vehicles and low-speed trucks.
- Adjustment of the standard name: from "electric horns for agricultural transport vehicles" to cover a wider range of three-wheeled vehicles and low-speed trucks.
- Update of technical indicators: Added wiring resistance accuracy requirements, adjusted the sound pressure level range and durability assessment times.
- Detailed test conditions: More stringent regulations on the test environment, instrument accuracy and operation procedures.
| Standard dimensions | 2003 version requirements | 2015 version update |
|---|---|---|
| Sound pressure level range (dB(A)) | Specific requirements not specified | Specified: 105~118 dB(A) |
| Number of durability tests | Three-wheeled vehicles: not specified; low-speed trucks: not specified | Three-wheeled vehicles: 15,000 times; low-speed trucks: 40,000 times |
| Wiring resistance accuracy requirements | Not mentioned | The resistance range under different voltages is clearly specified |
Comparison of standard framework and core changes
Main changes include:
- Expansion of application scope: from "agricultural transport vehicles" to a wider range of three-wheeled vehicles and low-speed trucks.
- Detailed performance requirements: added spectrum analysis requirements for sound pressure level and multi-tone speaker unit test methods.
- Optimization of test conditions: detailed provisions for the applicable scenarios of anechoic chambers, semi-anechoic chambers and open fields.
Implementation suggestions and practical application cases
In order to ensure the effective implementation of GB/T 19129-2015 standard, it is recommended that:
- Manufacturers:Strictly design and produce in accordance with the standard requirements, focusing on the sound pressure level, durability and wiring resistance accuracy of electric horns.
- Testing agency: Equipped with test instruments that meet the requirements (such as Class 1 precision sound level meter) to ensure that the test environment meets the specification requirements.
- User end: Pay attention to the operating voltage range and installation requirements of the electric horn during use to avoid performance degradation due to improper operation.
