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 7 test method standards are designed to ensure the strength and reliability of individual components and bicycles Meet the requirements, and require consideration of safety aspects from the design stage. The scope of GB (/T) 3565 is limited to product safety considerations. If bicycles are used on public roads, the "Chinese People's The Road Traffic Safety Law of the Republic and relevant 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 released 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 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.

Perforations shall be permitted in the handlebar cover for the installation of test fixtures. As long as the hole does not affect the positioning of the handlebar cover on the handlebar tube, and during the test, it is ensured that the fixing device does not interfere with the handlebar tube. touch. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 3565.5-2022_English be delivered?Answer: Upon your order, we will start to translate GB/T 3565.5-2022_English as soon as possible, and keep you informed of the progress.
