Introduction

Interpretation of the core content of the standard

Definition of step board: Step boards are installed on both sides or at the rear of M1 and G road vehicles for passengers to step on and get off the vehicle. They are divided into two categories: fixed step boards and movable step boards.

Comparison of key technical requirements

Performance indicators	Fixed treads	Electric treads	Mechanical treads
Load-bearing deformation	≤20mm(temporary) ≤3mm(permanent)	Same as fixed treads
Durability	-	86,000 times	20,000 times
Coating thickness	Powder coating ≥60μm Electrophoretic layer ≥10μm Oxide layer ≥10μm
Salt spray test	Powder coating 500h Electrophoretic layer 240h Chrome plating 24h

Key points for standard implementation

Key control of covering layer:The standard specifically stipulates the technical parameters of 6 types of surface treatment processes, among which the hardness of powder coating is required to be ≥2H, and the neutral salt spray test must pass 500 hours of testing.

Typical application case

In the development of an electric step board for a certain SUV model, the obstacle detection function required by clause 4.3.1.2 is realized by adding a Hall sensor, and the telescopic response time is controlled within 0.5 seconds.

Analysis of Standard Evolution

Innovation of the 2015 version: For the first time, the technical requirements for electric/mechanical stepping plates are distinguished, and electromagnetic compatibility (EMC) test requirements are added
Test method upgrade: The vibration test parameters are clearly defined as 67m/s² acceleration and 33Hz frequency, which is 30% more stringent than the old standard

Suggestions for enterprise implementation

Material selection: RoHS-certified aluminum alloy substrates are preferred, taking into account both lightweight and strength requirements
Process control: The electrophoretic coating line needs to maintain the bath temperature fluctuation ≤±1℃ to ensure the uniformity of film thickness
Testing equipment: Equipped with necessary instruments such as salt spray test chamber and cross-cut tester, and establish a rapid detection process for the covering layer
