Protective devices against unauthorized use for motorcycles and mopeds
摩托车和轻便摩托车防盗装置
GB 17353-2024 is a current mandatory Chinese national standard for Protective devices against unauthorized use for motorcycles and mopeds. It appears in the Electronics compliance cluster with a product safety focus and has an implementation date of Jan 1, 2026.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to motorcycles and mopeds (referred to as vehicles) and specifies the classification, requirements, and testing methods for protective devices installed as original equipment. It covers both locking devices (for steering or transmission mechanisms) and positioning devices designed to prevent unauthorized use or track unauthorized movement. It is mandatory for manufacturers seeking type approval in China.
Technical requirements
The standard classifies locking devices into four categories (Type I to IV) based on whether they lock the steering mechanism, prevent engine/motor start, or lock the transmission. Manufacturers must ensure that locks cannot be easily bypassed using common, inexpensive tools. It specifies minimum combination requirements for mechanical keys (at least 1,000 combinations) and electronic keys (at least 1,000,000 combinations). For locking devices, the standard mandates specific design criteria, such as ensuring the steering mechanism cannot turn when engaged and preventing accidental locking during vehicle operation. Locks must withstand specific torque values without failing or allowing unauthorized turning. For Type III devices, a minimum of 2,500 locking cycle tests is required to ensure durability. The standard introduces new requirements for positioning devices. These devices must provide real-time location tracking and reporting capabilities if the vehicle is moved without authorization. The positioning accuracy must meet strict horizontal and vertical error margins under specific testing conditions. Additionally, these devices must meet IP65 protection ratings and pass electromagnetic compatibility assessments. Electromagnetic immunity is a critical requirement. Electronic locking and positioning systems must withstand specified field strengths (e.g., 30 V/m) across a frequency range of 20 MHz to 2000 MHz without functional degradation or unintended power state changes. Pure mechanical locking devices are exempt from the EMC testing requirements.
Testing methods
The standard outlines several critical testing procedures: Lock Cylinder Torque Test (applying torque to verify lock integrity), Steering Mechanism Locking Torque Test (ensuring the steering column withstands applied force without damage), and Type III Locking Device Cyclic Test (durability testing over 2,500 cycles). It also includes Electromagnetic Compatibility (EMC) Tests for both locking and positioning systems in a semi-anechoic chamber, and Positioning Performance Tests (evaluating static and dynamic positioning accuracy using satellite signal simulators).
FAQs
What products are regulated under GB 17353-2024?
It applies to motorcycles and mopeds, specifically covering original equipment locking devices (for steering or transmission) and positioning devices designed to prevent unauthorized use or movement.
Are there any major updates from the previous GB 17353-2014 version?
The 2024 version introduces requirements for positioning devices, adds definitions for electronic keys and circular error probable, mandates engine/motor start prevention for Type II and III devices, and includes new tests for lock cylinder torque and static locking torque.
When does GB 17353-2024 take effect?
For newly applied type approvals, it is mandatory from January 1, 2026. For previously approved vehicle models, compliance is required starting 25 months after the implementation date.
