Provide all kinds of industrial machinery products testing certification
It mainly includes agricultural machinery, mining equipment, metallurgical equipment, power equipment, chemical equipment and working mother machinery and other manufacturing industries. Machinery manufacturing industry is the heart of the industry, it industry, agriculture, transportation, national defense, etc. To provide technical equipment, is the material of the national economy and defense modernization technology base, therefore, machine-building industry developed or not and machine and equipment level of self-sufficiency is to measure a country's economic development level and the real symbol of the levels of science and technology. There are many categories of machine manufacturing, which has become the largest industrial system with dozens of independent production departments. Because of the complex structure of machine products, parts and components, strong technology, so the implementation of production specialization, standardization, automation for the development of machine manufacturing industry is of great significance.
Product range:
Agricultural machinery, mining equipment, metallurgical equipment, power equipment, chemical equipment, digging machinery, shovel transport machinery, construction lifting machinery, motor industrial vehicles, compaction machinery, road machinery, piling machinery, concrete machinery, steel processing machinery, decoration machinery, drilling machinery, other special construction machinery.
Valve European Union CE certification in pressure equipment directive 97/23/EC valves belong to pipeline components, and according to the relevant technical parameters will be divided into class I, class II, class III three risk levels. Thus, regardless of the method of classification, the specified valve can be classified according to this instruction. Whether it is common valves such as gate valves, globe valves, ball valves, butterfly valves or safety valves, CE certification should be carried out according to the PED Instruction of pressure equipment.

1. Testing standard (part)
Country/Region | Safety | Electromagnetic compatibility |
IEC report | IEC61800-5-1 | IEC61800-3 |
The European | IEC61800-5-1 | IEC61800-3 |
China | GB/T12668.501 | GB/T12668.3 |
Valve according to different fluid, pressure, diameter, etc., is divided into I-IV class, which class IV safety level is high, the higher the certification requirements.
Class I form A
Class II form A1 form D1 form E1
Class III form B1+D form B1+F form B+E form B+C1 form H
Class IV form B+D form B+F form G form H1
Class IV is primarily applicable to safety valves,But as a special case, some special occasions of the safety valve can also be used to protect the equipment and the same danger level.
Certification program
Fluid condition: gas or liquid.A gas or liquid. At high valve operating temperature,The fluid and saturated vapor pressure (gauge pressure) do not exceed 0.5bar and are considered liquid, otherwise they are considered gas.

The standards applicable to mechanical products are generally divided into the following categories:
Class A standards (Basic safety standards)
It is mainly about basic concepts, design principles and general requirements applicable to all machinery.
Class B standards (safety standards)
are mainly used to deal with a safety situation or a related safety facilities, which can be widely used in a variety of machinery;
Class B1 standards for specific safety conditions (e.g., safe distance, surface temperature, noise)
The B2 standard is for relevant safety facilities (e.g., two-hand controls, interlocking devices, pressure sensing devices, shields).
Class C standards (Machine safety standards)
are mainly used for the detailed safety requirements of a particular type or class of machines.
Class C standard has the highest authority among these three standards, that is, if the same machine adopts class A, B and C standards at the same time, the requirements of class C standard have the highest priority. Class C standards are usually also called product standards. For example, EN201- Safety Requirements for Injection Molding Machines, which provides detailed and specific requirements for all possible risks of injection molding machines, basically including or referring to the requirements of class A and class B standards related to this type of products.
The most commonly used A, B and C standards for mechanical products are:
Class A standard: ENISO12100: Basic design Principles for Mechanical safety - Risk assessment and risk mitigation; .
Class B standard: ENISO13857: Safety of machinery - safe distance to prevent extension of upper and lower limbs and hazardous areas;
