Abstract: Mechanical coupling devices, such as trailer ball and tow hook, are commonly used to connect vehicles and trailers. They are very critical to driving safety in mechanical properties, so most countries have mandatory requirements for certification of this product. In order to ensure the safety requirements and international interchangeability of standard and non-standard mechanical coupling devices and components, ECE R55 provides for the above devices for use in Class M, N and O vehicles. ATIC has very rich experience in R55 project, and has helped Wuxi Jingdun, Jiaxing Paike, Jilin GM and other domestic Oems and parts manufacturers to obtain certification certificates.
Mechanical coupling devices and components listed below require R55 certification:
Class A Coupling balls and to wing brackets
Class B Coupling heads
Class C Clevis type drawbar c oupling
Class D Drawbar eyes
Class E Non-standard drawbar
ClassF Non-standard draw be ams
Class G Fifth wheel couplings
Class H Fifth wheel coupling pins
Class J Non-standard mounting plates
Class K Standard hook type couplings
Class L Standard toroidaldrawbar eyes for use with appropriate
ClassS Other coupling device
Class T Dedicated drawbar type couplings
Class W Non-standard miscellaneous，automatic drawbar coupling clevis type
For vehicles equipped with mechanical link devices or components conforming to R55, the installation height and Angle of the vehicle coupling device can be checked based on the R55 certificate of components.
THE CERTIFICATION PROCESS
Preparation of documents and samples
Sample delivery and testing
Preparation of reports
Submit for review
General Functional examination
Strength requirements（Dynamic and Static testing）
