Basis of Ce: basic requirements and harmonized standards
slowly open the oil delivery valve. On May 7, 1985, the European Council approved the resolution of 85/c136/01 on the new method of technical coordination and standardization. The resolution points out that in the new method directive, only the basic health and safety requirements that products should meet are stipulated, and in addition, coordinated standards are formulated to meet these basic requirements. Harmonized standards are formulated by the European Organization for standardization. Products that meet these standards can be regarded as meeting the basic requirements of EU directives
generally, all new method directives specify the basic requirements for affixing the "CE" mark. These basic requirements stipulate the basic elements that must be achieved to protect the public interest, especially the basic requirements for protecting the health and safety of users, such as consumers and workers, and other aspects related to the protection of property or the environment. The purpose of basic requirements is to provide and ensure high standards of protection for users. Some of these requirements involve some risk factors related to the product, such as mechanical resistance, flammability, chemical property, biological property, hygiene, radioactivity and accuracy; Or related to the product or its performance, such as the provisions on materials, design, construction, production process, and instructions prepared by the manufacturer; Or specify the main protection targets in the form of a list; More is the combination of the above methods. If a product has inherent hazards, it is necessary for the manufacturer to conduct hazard analysis to determine the basic requirements applicable to its products. These analyses should be compiled into documents and put into technical documents. The basic requirements specify the results to be achieved or the degree of danger involved, but do not specify or predict the technical solution. This flexibility provides manufacturers with the freedom to choose the construction flatness, and it is difficult to control the method to meet the basic requirements. Doing so can enable manufacturers to fully select materials or product designs suitable for technological progress
European standards that provide technical specifications for the basic requirements of the directive are approved by the organization for Standardization on the basis of unanimous adoption by the European Commission. This standard is called "coordination standard", which is a "fast track" that meets the basic requirements of the directive. The harmonized standard has the status of "inferring from this that it meets the basic requirements". It is a tool for manufacturers to prove that products meet the basic requirements of the directive, that is, products that meet the harmonized standard can be circulated in the EU market, but the implementation of the harmonized standard is still voluntary
the harmonized standard involves not only the relevant provisions of the basic requirements, but also other provisions, but the manufacturer should distinguish other provisions from the basic requirements in the implementation. Sometimes, a harmonized standard does not cover all the basic requirements of its corresponding directive. In this case, the manufacturer should adopt other technical specifications, In order to ensure compliance with the directive, song Wangqiu's answer is: "imagine the basic requirements of the future with renewable materials.
according to the provisions of the European Organization for standardization, Member States must convert the harmonized standards into national standards and withdraw national standards that are contrary to the harmonized standards, which is mandatory. The harmonized standards are not listed separately in the European standards, and their titles, codes, etc. should be published in the official gazette of the European Union (official journal) and specify the corresponding new method instructions.
