On September 1, 2013, China's "Post Bumper" industry standard will be officially implemented. The standard will be drafted by the group. Many domestic research institutes and professional institutions will participate in the demonstration, and in April 2014, it will pass the national industry and Approval by the Ministry of Information Technology. The implementation of the protective bar industry standard will guide the rear bumper and bumper production enterprises to strictly follow the national and industrial standards for production.
The "back bumper" industry standard meets the requirements of national mandatory laws and standards, for example, the collision performance of products, the standard meets the relevant requirements of GB173521998. At the same time, the standard provides a measure of the material, process and performance of the rear bumper on the basis of the mandatory regulations for ensuring the safety of the national product, and proposes scientific testing of the test method. For example, for the problem of “back bumper paint drop”, the method of coating adhesion test is specified; due to the characteristics of automobile products, the problem of falling off and looseness is easy for inferior products, the standard specifies the vibration resistance performance clause, and the installation bracket is clearly defined. Install the reinforcing plate and the protective bar without cracking, desoldering and obvious looseness; as the case may also apply the general requirements of the structural design of the standard, that is, the aerodynamic characteristics of the vehicle should be considered, and the protective bar should not be significantly increased after installation. The air resistance of the whole vehicle and so on.
The "Post Bumper" standard provides detailed explanations on the functional positioning, material application, performance standards, testing methods, production techniques and installation specifications of the rear bumper, and puts forward strict requirements.
After the standard is released, the product inspection process can be initiated in three ways:
First, after the consumer encounters product quality problems, the quality inspection department may be required to inspect the problem product;
Second, the national quality inspection department shall randomly check the problem products according to law;
Third, companies or individuals report fake and shoddy products.
After the inspection by the authoritative quality inspection department, the damage caused by the products that do not meet the "back bumper" industry standard shall be borne by the production enterprise and the seller according to law.
