Relevant requirements help companies to  establish a good social image.

3. OHSAS 18000

OHSAS18000 is the full name of Occupational Health and Safety Assessment Series 18000, an international safety and health management system validation standard. The development of OHSAS is mainly to solve the problem of how to choose between the customer base and the security management system verification standards developed by many verification organizations: and replace the well- known BS8800 to become an officially verifiable international standard.

The implementation, implementation and certification of the occupational safety and health management system can ensure that the company can provide an environment for all employees to control occupational safety and health requirements, and ensure that the various interests of employees, enterprises and related parties are met.


4. EU CE Certification

The CE certification mark is a safety certification mark and is regarded as a passport that the  manufacturer opens and enters the European market. Products bearing the "CE certification" mark can be sold in the member states of the European Union without complying with the requirements of each member state, thus realizing the free circulation of goods within the EU member states.

In the EU market, the “CE” mark is a compulsory certification mark. Whether it is a product produced by an enterprise within the EU or a product produced by another country, in order to be  freely circulated in the EU market, the “CE mark” must be affixed to indicate that the product meets the requirements. The basic requirements of the EU Directive on Technology Coordination and  Standardization. This is a mandatory requirement for products in EU law.

PED certified product range:

  • Pressure vessel: refers to a confined space that holds a fluid and carries a certain pressure.
  • Pressure pipe: A general term for pipes that transfer fluid between pressure-bearing systems. The pressure pipe can be either a single pipe or a pipe system consisting of pipes, fittings, expansion joints, hoses and other pressure-bearing components.
  • Safety accessories: Devices used to prevent pressure-bearing equipment from exceeding the permissible limits. Includes: Direct pressure limiting devices - such as safety valves, rupture  discs, yielding levers, controlled safety release systems (CSPRS); restriction devices-pressure switches, temperature control valves, level gauges, and safety-related adjustment controls (  SPMCR)
  • Pressure-bearing accessories: devices with a certain function and a certain pressure space.
  • Complete equipment: A combination of two or more pressure-bearing equipment with an overall function.

5. CU-TR

In order to make the trade between the Union countries easier, and in order to avoid the technical and technical barriers to import and export products within this customs union, the Customs Union legislation issues the mandatory Customs Union TR technical regulations certificate, Customs Union  Technical Regulations certificate: is proof This product is the only proof of the customs union's technical regulations, which apply to: Russia, Belarus, Kazakhstan

6. API Certification

API is the abbreviation of American Petroleum Institute, founded in 1919, according to the characteristics of the industry and the needs of the industry itself. In 1924, the API specification was formulated to provide technical guidance for the production of related products in the petroleum industry. As API specifications developed by API organizations are expanding with the advancement, versatility, security and influence of the US petroleum industry worldwide, API specifications have been widely adopted in countries around the world.

The API standard mainly specifies equipment performance, and sometimes includes design and process specifications. The standards development areas include oil production, refining, measurement, transportation, sales, safety and fire protection, environmental regulations, etc. The information technology standards include EDI for the oil and gas industry. , communications and information  technology applications.

The API enjoys high prestige in the United States and in other countries around the world. It is a petroleum machinery certification body recognized by the US Department of Commerce and the US Trade Commission. Its petrochemical and oil recovery machinery technical standards have been  adopted by many countries. Oil companies in many countries in the Middle East, South America and Asia generally require products with API mark to be eligible for bidding when bidding for petroleum machinery. Therefore, the petroleum machinery equipment with the API mark is not only considered to be of reliable quality but also of advanced level, and the products are accepted and trusted by users when they enter the international market.

7. SIL

SIL (Safety Integrity Level) - Safety Integrity Level.

The SIL technical standard was first promulgated by the International Electro technical Commission (IEC) and implemented by IEC/TC65. The National Standardization Technical Committee of SIL Technology is the “National Process Industry Measurement Control and Automation” Standardization Technical Committee (SAC/TC124), and the Secretariat is the Institute of Mechanical Industry Instrumentation Integrated Technology and Economy.

SIL certification is divided into 4 levels: SIL1, SIL2, SIL3, SIL4, including two levels of product and system, of which SIL4 has the highest requirements.

8. Fire Test Certification

API 607 and API 6FA are fire tests for valves 6D and 6A. Generally, only 6° valves that rotate 90 ° require API 607, while others require API 6FA. PAI is the abbreviation of American Petroleum Institute. 6FA is a fireproof certification for 6A standard valve fire test, and a 607 fire certification for 6D (refers to only 90 degree valve) standard valve fire test certification.

The European explosion-proof directive ATEX (94/9/EC) was enforced from July 1, 2003. This directive applies to both electrical and non-electrical equipment, including various explosion- proof electrical equipment, protection systems, safety equipment, control instruments, and regulating devices.

ATEX explosion-proof directive core requirements:

Protect people's safety and health, and in some cases protect the health and property of livestock, especially to protect workers from the hazards of equipment and systems suitable for potentially explosive environments.

Manufacturers wishing to enter Europe and sell products for explosive atmospheres in Europe must demonstrate that their products comply with the ATEX Directive 2014/34/EU.

There are three prerequisites for applying this directive:
1. The equipment must have its own ignition source;
2. Expected to be used in potentially explosive atmospheres (air mixtures);
3. It is under normal atmospheric conditions.
This directive also applies to the components necessary for safe use and to the safety devices  that are directly beneficial to the safe use of the equipment. These devices can be external to potentially explosive atmospheres.


11. IP protection level test (INGRESS PROTECTION)

The IP protection rating system was drafted by the IEC to classify electrical appliances according to their dust and moisture resistance characteristics. The foreign objects referred to here include tools, human fingers, etc., which are not accessible to the live parts of the appliance to avoid electric shock. The IP protection level is composed of two numbers. The first number indicates the level of dustproofing and prevention of foreign objects entering the appliance. The second number indicates the degree of airtightness of the appliance against moisture and water intrusion. The larger the number, the more the protection level is high.
