1. EU Machinery Directive
The EU machinery directive is not aimed at technical details, but focuses on mechanical design and safety and health regulations related to the organization. The current Machinery Directive (98/37/EC, which was promulgated by the EU official gazette in July 23, 1998), replaces the 1989 issue of 89/392/EEC, and the subsequent revised directives 91/368/EEC, 93/44EEC and 93/63/EEC. Since January 1, 1995, the machinery directive has become a mandatory European law, and all EU member states have to incorporate some of their basic provisions into the laws of their respective countries.
The European Union Machinery Directive 98/37/EC applies to all kinds of machinery and safety parts sold in the market, but it is not applicable to some specific machinery. The complete specification of machinery directive, application release and CE markers including the declaration of conformity, also apply to second-hand or renovated machinery, including: the first import countries outside the EU, the European economic area to the new or renovated machinery used in the region. New machinery, assembled and disassembled from all over the world, has new design and new risks.

1) the machinery described in the mechanical instruction"
The machinery described in the mechanical instruction includes a single machine, a connected set of machinery, and a replaceable device.
1. mechanical assembly of several parts which connected, wherein at least one of the parts can be connected through proper motion, and brake control device and the power circuit, and a specific purpose, such as material processing, processing, handling, packaging, etc.. Mainly includes the following types of products: wood processing machinery, metal cutting machine tools, forging machinery, agricultural and forestry tractors and machinery, rubber and plastic machinery, packaging machinery, lifting transportation machinery, storage equipment, construction machinery, food processing machinery, heat treatment equipment, underground mining machinery, printing and papermaking machinery, casting machinery, textile machinery, washing machine, compressor, engine, pump, tanning machinery, fire fighting equipment etc.. For those machines which are packaged and disassembled for transport purposes, they shall be assembled together when they are used, so the instructions shall also be followed.
2., the mechanical combination, in order to achieve the same purpose, by a number of machines after proper configuration and control, to become a comprehensive whole, to achieve complete function. Such as automatic production line and flexible manufacturing system.
3. replaceable equipment refers to equipment that can be replaced, can change the mechanical function, the equipment can be put into the market, they will be used by the operator and one or a series of different mechanical traction machine assembly together, the device is not spare parts or tools. These devices can provide power, such as the end of a car mounted on a machine tool.
Mechanical instruction in the safety parts of the equipment above is not replaceable, it is sold by the manufacturer or its determination in the EuropeanCommunity authorized agents in the market, the implementation of security function in the use of spare parts, his failure would endanger the health or safety of exposure (here refers to the body exposure all or part of any personnel in the hazardous area). For example, the rope, emergency stop device, logic component with both hands control, electronic sensitive device, drop protection device and overload protection device designed for protection personnel.
2) machinery that is not suitable for mechanical instruction
The term "machinery" covers any kind of equipment, whether for domestic, commercial, or industrial use, consisting of parts that are powered by electricity rather than by human power. There are exceptions, however. Some machines are not included in the mechanical instructions, but are covered by other instructions. For example, when the mechanical risk is related to the power supply, it is included in the Low Voltage Directive (73/23/EEC). These machines are included in the low voltage directive standard issued by the official gazette.
Specifically, machinery that is not suitable for mechanical instruction:
Only taking human as a power source for lifting machinery, but the mechanical load to direct contact with patients; medical equipment; market places or (and) special equipment playground; tank and steam boiler, pressure vessel; mechanical and special design or application for nuclear use, in the event of failure, will cause radioactive radiation; the radioactive source of mechanical parts forming; light weapons; gasoline, diesel oil, nuclear tank pipeline of inflammable liquid and hazardous substances; transport, are those by aviation, highway, railway, waterway and other public transport network to transport. Passenger tool and trailer, and device for carrying goods by air, road, railway, waterway and other transportation network. The mining industry with the vehicle is allowed except; oceangoing ships and offshore mobile equipment, together with its equipment; public or private manned cableway (including cable car); 74/150/CEE (unified instruction on each member of wheeled agricultural or forestry tractor setting law) clause 1 (1) tractors for agriculture and forestry is defined as; military or police mechanical design and manufacturing;
A permanent lifting device for a particular height of a building, with a carriage moving between rigid rails, with the inclination of the guide rail and the horizontal plane greater than 15 degrees, designed to carry:

   1. personnel
2. personnel and goods
3. of the goods, but the car can enter, that people can easily enter the car, equipped with the controller in the car in the car or in the range of accessible; personnel transport device installation of the gear and the rack rail vehicle; mine hoist device; lift stage; construction site hoists transporting people or people and goods.
Is the CD player considered mechanical because of active components? Of course not. Although many products have different forms of moving parts, they are not included in the scope of the instructions. At the same time, "activity" must be due to external kinetic energy (electricity, batteries, fuel, etc.), or energy storage (spring, weight). In addition to this provision, the machinery directive covers some direct lifting equipment for human use. Other machines which are directly driven by manpower are not listed here. In addition, the main risks arising from the product must be mainly mechanical power, not electricity related.

2. requires a EC declaration of conformity and additional CE mark products
For the products included in the mechanical instructions, the CE mark is a mandatory sign. CE is abbreviated as Conformity European. Before legally binding the CE mark on the machine, the manufacturer must issue a "qualified statement" (Doc), which is the duly signed document, indicating the basic requirements for all applicable instructions. CE signs represent conformity to statutory specifications, neither quality nor safety signs. The CE logo can be placed on the machine with third party safety signs to show its principle of good faith. If there is no CE mark, has failed to comply with the provisions of the directive, products will not in the European Union and the European Economic Zone "on the market or put into use, however, if the product can meet the applicable provisions of the EU directive, will not be affected by these countries prohibit, restrict or prevent. As a result, the CE mark is considered a "pass" for the products to circulate in europe".

3. requirements for the preparation of EC qualification statements
1. in the annex to the directive, II specifies the content to be included in the EC Qualification Statement. Generally speaking, the following contents are included:
The name and address of the manufacturer or its authorized agent in the European Community; information on the structure, type, sequence number, etc. of the product;
The product complies with the relevant instructions and, if necessary, includes the standards adopted;
Where necessary, it includes the name, address and relevant certification matters of the notified institution; the identity and signature of the authorized agent of the manufacturer or its common body in the European community;
For machinery that will not operate independently of a machine, the statement shall also state that "the machinery shall not be used until the machinery is incorporated into the machinery and that it has not yet been in conformity with this directive.""
2.EC qualification statements must be written in the same language as mechanical instructions. It is accompanied by the translation of the official language of the country of use of the machinery. The qualification statement should be typed and clearly written.

4. annex I: mechanical command core
For manufacturers, the "annex I" is the core and essence of the machinery directive ". "Annex I" not only provides a broad list of potential hazards caused by design and operation, but also provides general guidelines for avoiding those risks. The basic provisions in the mechanical instructions are as follows:
Basic health and safety requirements; for certain types of machinery; additional basic health and safety requirements (crop machinery, portable and / or manual machinery, wood and similar materials processing machinery);
Eliminates mechanical affects caused basic health and safety regulations especially dangerous; eliminates the lifting operation caused by the basic health and safety regulations especially dangerous; basic health and safety regulations for underground special machinery;

5. standard: a tool for proving compliance with instructions
Compliance with applicable EU harmonized standards and recommendations for achieving the basic health and safety requirements of mechanical orders. The standard plays an important role in the implementation of EU directives, and all directives are presumed to be in accordance with the provisions of the directive on the basis of the so-called "harmonization" of European standards. Harmonized standards of instruction must be published in the official European Union publication.
The European Union Standards Committee (CEN) is committed to developing an integrated version to cover three categories of European standards to support mechanical instructions. The first class (A) standard includes the general principles of various mechanical designs (e.g., EN292 mechanical design or EN 1050 risk assessment).
The second class of standards (B) covers ergonomics of specific safety devices and mechanical types (e.g., EN 418 emergency stop equipment, or EN 574 hand control).
Finally, the third class of standards (C) covers specific mechanical classifications that refer to the first two classes of standards, and focuses on specific mechanical requirements (e.g., EN201 for injection molding machines, or EN 474 for earthmoving machines). So far, most of the A and B standards have been promulgated, but about 600 technical committees and working groups are still working on the C standards, but the machinery in Annex IV is preferred. Prediction still needs years, C standard can be announced in full. At the same time, through class A and class B standards and the adoption of most general product standards, it is possible to confirm the basic requirements of the regulation. The following are the major coordination standards for mechanical instructions:

    EN, 292-1, -2: Mechanical Safety - basic concepts, general principles of design
EN 1050: Mechanical Safety - risk assessment principles
EN 60204-1: Mechanical Safety - Mechanical and electrical equipment
EN 954-1: Mechanical Safety - Safety parts of control systems
EN 294: Mechanical Safety - Safety Distance
EN 349: to prevent the smallest clearance of the human body
EN 418: Mechanical Safety - emergency shutdown
EN 1088: mechanical safety interlock
EN 775: automatic mechanism

6. mechanical and safety components of the EC type test must be carried out by the public notices
Broadly speaking, mechanical instructions divide machines into two classes: dangerous machines, ordinary machines. High submersible dangerous machinery and selected safety parts are listed in the machinery directive annex IV. Such products should have special regulations. As listed in Appendix I, the manufacturer shall include the participation of the announcement body before adding the CE mark (generally speaking, the issuing organization will issue a EC type test certificate). All other machinery shall comply with the basic health and safety requirements specified in Annex I of the directive, but the manufacturer or importer shall also carry out its conformity assessment on its own. The manufacturer shall then submit technical documentation, qualification statements and posting CE marks.
Following are the mechanical and safety components that must be tested by the public announcement for type EC testing:
A. machinery

7. risk analysis and risk assessment
Under the machinery command, the manufacturer's primary responsibility is to perform risk analysis and risk assessment. The hazard analysis is to use the instrument to confirm the hazards of the machine in different life cycles and to take preventive measures when necessary. The so-called risk assessment is a series of logical actions aimed at reducing and eliminating risks. EN 1050 lists several risk assessment methods and techniques. EN 1050, along with EN954-1, describes the performance classification of components for designing safety control systems. EN954-1 not listed should use what security function, when the severity of the potential hazards based on risk assessment, position and frequency, the probability of occurrence, the designer should read the instructions, to learn how to design a safety circuit and how to select the appropriate safety parts. In accordance with the three factors listed above, the manufacturer may determine the relevant safety classifications used by the machinery.

10. technical documentation (TCF)
Another responsibility of the manufacturer or its authorized representative in the European Union is the establishment of technical records. The file contains data that is mechanically consistent with instructions. Within ten years from the date of mechanical production, the technical archives shall be readily available for inspection by the national market supervision and control units at any time. The technical documentation shall contain relevant design, construction, risk assessment and compliance validation documents (e.g. test data), and related manuals. The number of pages of technical records depends on the nature of the machinery and the chosen means of compliance (e.g., the use of proven engineering practices rather than harmonized standards).
The contents of technical documents shall normally include product design, manufacture and use:
