To produce bicycles that are as safe as possible. GB (/T) 3565 "Bicycle Safety Requirements" consists of 9 parts. --- Part 1.Terms and definitions. The purpose is to unify the terminology used in each part of the standard. --- Part 2.Requirements for city and touring bicycles, youth bicycles, mountain bikes and racing bicycles. purpose is Classify the safety requirements of Category 4 bicycles into mandatory national standards for easy enforcement. --- Part 3.General test methods. The purpose is to centralize and unify the general test methods for bicycle safety requirements and facilitate operation. --- Part 4.Brake test method. The purpose is to carry out professional tests on the brake requirements in the bicycle safety requirements, and provide a basis for the brake test Opportunities for method improvement. --- Part 5.Test methods for handlebars. The purpose is to carry out professional tests on the handlebar requirements in the bicycle safety requirements, and to provide a basis for the handlebar test Opportunities for method improvement. --- Part 6.Test methods for frame and fork. The purpose is to conduct a professional review of the requirements for frame and front fork in bicycle safety requirements. Test and provide opportunities for improved test methods for frames and forks. --- Part 7.Test methods for wheels and rims. The purpose is to conduct a professional review of the requirements for wheels and rims in bicycle safety requirements Test and provide opportunities for improvement of test methods for wheels and rims. --- Part 8.Test methods for pedals and drive systems. The purpose is to meet the requirements for pedals and drive systems in bicycle safety requirements Conduct specialized tests and provide opportunities for improved test methods for pedal and drive systems. --- Part 9.Test methods for saddles and saddle tubes. The purpose is to conduct a professional review of the requirements for saddles and saddle tubes in bicycle safety requirements Test, and provide opportunities for the improvement of test methods for saddles and saddle tubes. GB 3565.2 is a mandatory national standard, and 7 test method standards (GB/T 3565.3~GB/T 3565.9) are recommended national standards Standard, used in conjunction with GB 3565.2.These test method standards are designed to ensure the strength and reliability of individual components as well as the complete bicycle It meets the requirements and requires consideration of safety issues from the design stage. The scope of GB (/T) 3565 is limited to product safety considerations. If bicycles are used on public roads, national road traffic regulations must be followed. Communication safety laws and related management regulations. To improve repeatability and reproducibility, and to take into account suitability, size and operator effects for all types of bicycles, the test The machine test method reflects the current advanced level and is more popular than the road test method. The safety and quality of bicycles is related to the traffic life safety of consumers. Since 1983, my country has released three versions of GB 3565.It has been 17 years since GB 3565-2005 was issued and implemented. Provided technical support. GB 3565-2005 "Safety Requirements for Bicycles" is equivalent to ISO 4210.1996 "Safety Requirements for Two-wheeled Bicycles" Require". In.2014, ISO 4210 was revised and released again, from the original 1 standard to 9 standards. For this reason, GB 3565 also changed from the original 1 One standard was revised into nine standards, and the standard level was synchronized with the international standard, and continued to provide technical support for the safety of bicycle products in my country. Bicycle Safety Requirements Part 9.Test methods for saddles and saddle tubes1 ScopeThis document describes the clamping of bicycle saddles to saddle tubes, static load strength, fatigue tests, fatigue tests plus static load strength tests method.

GB/T 3565.3-2022 Bicycle Safety Requirements Part 3.General Test Methods (ISO 4210-3.2014, IDT)3 Terms and DefinitionsThe terms and definitions defined in GB/T 3565.1 apply to this document.4 Test method4.1 Overview For shock-absorbing saddle tubes, the test can be carried out with the shock-absorbing device in a free state or in a locked state. If the shock absorber is locked, the saddle tube The test shall be carried out at the maximum length. 4.2 Saddle/saddle tube---clamping test Correctly assemble the saddle tube on the bicycle frame with the minimum insertion depth (see the requirements of 4.16.2 in GB 3565.2-2022), according to the The saddle clamping bolts should be tightened to the torque recommended by the manufacturer, and the saddle should be connected to the saddle at the position indicated on the saddle beam mark or instruction manual provided by the saddle manufacturer. Tube clamped. At a distance of 25mm from the front or rear end of the saddle, select the point that produces the maximum moment on the saddle to apply a downward vertical force F1, keep The force is applied for 1min; after the force is removed, at a distance of 25mm from the front or rear end of the saddle, select a point that produces the maximum moment on the saddle to apply a lateral force. Horizontal force F2 (see Figure 1), maintain the force 1min. The force values are given in Table 1.The test equipment should not cause damage to the surface of the saddle. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 3565.9-2022_English be delivered?Answer: Upon your order, we will start to translate GB/T 3565.9-2022_English as soon as possible, and keep you informed of the progress.
