Mechanical equipment testing

Mechanical

Mechanical MD certification
 
According to Article 1.2 of the Machinery Directive, any combination composed of components. At least a portion of it is used for the purpose of raw material processing, handling, transportation, or packaging, and is moved through appropriate actuators, controllers, or circuits, all of which are called "machinery". The term 'machinery' also includes a group of machines arranged and controlled to achieve comprehensive functions such as raw material processing, handling, transportation, packaging, etc. In addition, some "security components" that ensure safety during use and pose a risk to the safety or health of personnel exposed to them in the event of failure also fall within the broad scope of machinery covered by this directive.
Scope of Mechanical Instruction Products
According to the provisions of the Machinery Directive, the following types of machinery are not within the scope of this Directive (Article):
1. Design and manufacture lifting and/or transportation equipment for passenger transport, regardless of load, except for industrial trucks equipped with lifting operators.
2. Machinery powered solely by human labor, unless used for stacking goods.
3. Medical machinery that comes into direct contact with patients.
4. Special equipment for outdoor squares or amusement parks,
5. Steam boilers, tanks, and pressure vessels,
6. Machinery specially designed or applied for nuclear energy purposes, which may result in the leakage of radiation energy in the event of an accident,
7. Radiative components constitute a part of the machine,
8. Light weapons,
9. Storage tanks and pipelines for gasoline, diesel, flammable liquids, and dangerous goods,
10. Transportation vehicles: Refers to those transportation vehicles and their trailers that use public transportation networks such as highways, railways, waterways, and air to transport personnel and/or goods, all of which should be considered as transportation vehicles. However, transportation vehicles used in the mining industry are included in this directive.
11. Ships and offshore mobile equipment equipped with relevant equipment.
12. Cable cars for public or private transportation, carrying passengers, and cable cars powered by ropes.
13. Agricultural forest traction machines, as defined in Article 1 (1) of Directive 74/150EEC, which pertains to the certification of wheeled agricultural or forest traction machines in the European market, as amended by Directive 88/29/EEC (2).
14. Machines specially designed and manufactured for military or police use
15. A lift permanently used in a building or structure within a specific height range. The active carriage is fixed between the guide rails at an angle of more than 15 degrees from the horizontal and designed for transporting:
- Personnel,
- Personnel and goods,
Goods, but with personnel accessibility. That is to say, personnel can easily enter it, and its control part is located inside the car and within reach of personnel.
- Vehicles used for carrying passengers and climbing with small gears and racks.
Mining cutters,
- Theater elevators,
- Cranes used on construction sites for carrying people or simultaneously carrying people and goods.
In addition, if the hazards related to machinery or security components mentioned in Directive 392 are covered in whole or in part by other European directives and are subject to their implementation, this Directive shall no longer apply or shall cease to apply to these products.

Classification of mechanical instruction products:
Machinery in the European Union is divided into ordinary machinery and dangerous machinery. The Machinery Directive stipulates that for mechanical products and safety components belonging to Appendix IV (dangerous machinery, such as punching machines, injection molding machines, high-altitude work platforms, woodworking saws, etc., which specific products are dangerous machinery), they belong to dangerous machinery, and certification agencies must conduct EC type testing, with relatively strict requirements.
The Machinery Directive (2006/42/EC) applies to machinery, mobile machinery, mechanical devices, machines used for lifting and transporting people, and safety accessories. The Basic Health and Safety Requirements (EHSR) stipulated in regulations cover the entire field of mechanical engineering
Procedure for applying for CE certification
1. Application submitted by the enterprise
2. Both parties sign a certification contract
3. Enterprises provide testing samples and technical documents
4. Conduct sample testing and technical document review
5. Issue compliance certificates
6. Enterprises issue qualified declarations
7. The enterprise shall affix the CE mark on the product
 
Mechanical product evaluation is mainly divided into safety assessment of machinery and safety testing involving electrical energy devices
Regarding the electrical energy requirements, the product must meet the requirements of the Low Voltage Directive and the Electromagnetic Compatibility Directive (EMC). The requirements for the EMC directive are strict, requiring products not only to not emit electromagnetic interference but also to be resistant to electromagnetic interference. Any electronic product must pass CE certification to demonstrate its universal recognition in the European Union.

Risks associated with non-compliance with CE marking
Once attempting to clear customs, if detected by customs, not only must the original goods be returned, but the EU authorities will also inform member states that the product is prohibited from being cleared within the EU.
2. If deceived through customs (including failure to affix CE markings, or failure to comply with requirements to affix CE markings arbitrarily), it may also be reported by peers or accused by consumer protection groups within the European Union, causing significant damage to the manufacturer's reputation.
Once a dangerous accident occurs with such products, they will bear a heavy liability for compensation due to failure to fulfill their safety protection responsibilities; It is even highly likely to be judged as intentional negligence and subject to punitive damages.
