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

Gold treatment machinery is often used in the gold treatment industry in refining, ingot casting, rolling, handling and packaging. This kind of machinery product must apply for the EU mandatory certification when exporting to the EU, so that the product can be circulated in the market.

1. Testing standard (part)

Testing standard

Bsen14753-2007 Machinery - Requirements for machinery and equipment for continuous casting

En 14677:2008 Machinery -- Outside furnace refining -- Machinery and equipment for the treatment of liquid steel

En14681:2006 +A1:2010 Mechanical - Requirements for machinery and equipment for steelmaking by electric arc furnaces

En15093:2008 Mechanical - Requirements for hot flat mills EN15094:2008 Mechanical - Requirements for cold flat mills

The test items

Metallurgical machinery is generally accompanied by high temperature, for such machines, attention should be

paid to the protection of on-site operators

1. The working area must be equipped with escape channels, escape channels must be kept clear, and there is no

accumulation at the corner of the stairs

2. At the entrance of stairs on the ground, isolation doors need to be installed. Only personnel with operating

ability can open them

3. The temperature in the area where the operator may reach should not exceed 60℃. Otherwise, protective

measures, such as thermal insulation cotton, must be installed

4. Moving parts, such as gear drive and chain drive, must be protected by a closed shield

5. In a relatively closed area, it is necessary to have a test device to test the concentration of combustible

substances, and alarm when the maximum allowable concentration

6. The internal environmental noise of the control room should be no more than 70B, otherwise the sound

insulation effect of the control room should be increased

7. The height of the operation box or the operation screen should conform to the ergonomics principle and be

between 1.2m and 1.5m

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;
ENISO4413: Hydraulic systems - General requirements and safety specifications for hydraulic systems and hydraulic components;
ENISO4414: Pneumatic systems - General requirements and safety specifications for hydraulic systems and hydraulic components
EN1088: Safety of machinery - Interlocking devices mounted on shields - General principles of design and methods of selection;
EN953: Safety of machinery - General requirements for the design and construction of stationary and mobile shields;
En60204-1: Safety of machinery - Mechanical electrical equipment - Part 1: General requirements.

Class C standard :EN201: Plastics and rubber machinery - Safety requirements for injection molding machines
En415-1: Safety of packaging machinery - Part 1: Terminology and classification of packaging machinery and related equipment;
En415-5: Safety of packaging machinery - Part 5: balers;
En474-1: Earth-moving machinery - Basic safety requirements
EN692: Machine tools - Safety of mechanical presses;
EN693: Machine tools - Safety of hydraulic presses;
EN860: Woodworking machinery - Single plane;
EN869: Safety of machinery - Metal die casting machines;
EN1493: Automotive lifter;
EN12417: Machine tools - Safety requirements for machining centres;
EN12717: Safety of machine tools - Drilling press;
