CE marking
Existing in its present form since 1985, the CE marking indicates that the manufacturer or importer claims compliance with the relevant EU legislation applicable to a product, regardless of the place of manufacture. By affixing the CE marking on a product, a manufacturer effectively declares, at its sole responsibility, conformity with all of the legal requirements to achieve CE marking which allows free movement and sale of the product throughout the European Economic Area.

For example, most electrical products must comply with the Low Voltage Directive and the EMC Directive; toys must comply with the Toy Safety Directive. The marking does not indicate EEA manufacture or that the EU or another authority has approved a product as safe or conformant.[4] The EU requirements may include safety, health, and environmental protection, and, if stipulated in any EU product legislation, assessment by a Notified Body or manufacture according to a certified production quality system. The CE marking also indicates that the product complies with directives in relation to "Electro Magnetic Compatibility"[5] - meaning the device will work as intended, without interfering with the use or function of any other device.

Not all products need CE marking to be traded in the EEA; only product categories subject to relevant directives or regulations are required (and allowed) to bear CE marking. Most CE-marked products can be placed on the market subject only to an internal production control by the manufacturer (Module A; see Self-certification, below), with no independent check of the conformity of the product with EU legislation; ANEC has cautioned that, amongst other things, CE marking cannot be considered a "safety mark" for consumers.[6][need quotation to verify]

CE marking involves self-certification. Retailers sometimes refer to products as "CE approved", but the mark does not actually signify approval. Certain categories of products require type-testing by an independent body to ensure conformity with relevant technical standards, but CE marking in itself does not certify that this has been done.

Countries requiring the CE marking
CE marking is a certification mark that indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA).
CE marking is mandatory for certain product groups within the European Economic Area (EEA; the 28-member states of the EU plus EFTA countries Iceland, Norway and Liechtenstein) plus Switzerland and Turkey. The manufacturer of products made within the EEA and the importer of goods made in other countries must ensure that CE-marked goods conform to standards.

As of 2013, CE marking was not required by countries of the Central European Free Trade Agreement (CEFTA), but members Republic of Macedonia, Serbia, and Montenegro had applied for membership of the European Union and were adopting many of its standards within their legislation (as did most Central European former member countries of CEFTA that joined the EU, before joining).

The manufacturer of a product affixes the CE marking to it but has to take certain obligatory steps before the product can bear CE marking. The manufacturer must carry out a conformity assessment, set up a technical file and sign a Declaration stipulated by the leading legislation for the product. The documentation has to be made available to authorities on
 
CB certification
 The IECEE-CB system is the most successful multilateral certification system for IEC International Electrotechnical Commission.
The International Electrotechnical Commission (IEC) is an international standards organization that prepares and publishes International Standards for all electrical, electronic and related technologies – collectively known as "electrotechnology". IEC standards cover a vast range of technologies from power generation, transmission and distribution to home appliances and office equipment, semiconductors, fiber optics, batteries, solar energy, nanotechnology and marine energy as well as many others. The IEC also manages three global conformity assessment systems that certify whether equipment, system or components conform to its International Standards.
Currently, 82 countries are members while another 82 participate in the Affiliate Country Programmed, which is not a form of membership but is designed to help industrializing countries get involved with the IEC.
 
Gulf Countries GCC
The GCC Standardization Organization (GSO) is a standards organization for the member states of the Gulf Cooperation Council and Yemen. It was established under the authority of the Gulf Cooperation Council. Its full official name is "the Standardization Organization of the Cooperation Council for the Arab States of the Gulf". The GSO's Technical Council mandated the creation of a regional Metrology Organization to be called "GULFME".

As at 2010, the GSO has mandated some 2,700 standards. Implementation of these standards is the responsibility of individual member countries of the GCC Saudi Arabia SASO certification

SASO is the abbreviation of Saudi Arabian Standards Organization. SASO is responsible for setting national standards for all daily necessities and products. Standards also include measurement systems, labels, etc. In fact, many of the SASO standards are based on the safety standards of international organizations such as the relevant International Electrotechnical Commission (IEC). Like many other countries, Saudi Arabia has added some unique items to the standards based on its own national and industrial voltages, geography and climatic environment, and ethnic and religious customs. SASO standard is required for products imported and produced in Saudi Arabia.
Russia and other countries CU
On July 1, 2010, Russia, Belarus, and Kazakhstan established the Customs Union system to eliminate or reduce trade barriers and promote trade cooperation. At the same time, it began to unify the technical and regulatory requirements of the Customs Union’s import and export products. The certificate is applicable to the entire territory of Russia, Belarus and Kazakhstan.
From February 15, 2013, products imported into the three countries (Russian, Kazakhstan, and White) under the jurisdiction of the Customs Union (CU) must apply for and obtain a CU-TR certificate. Certifications, including Russia's GOST-R certificate, Belarusian GOST-B certificate, Kazakhstan's GOST-K certificate are replaced by CU-TR certificate.
The Cu stomps Union CU-TR certificate applies to:
Mechanical equipment, low-voltage electrical equipment, gas equipment, elevators, explosion-proof products, toys, personal protective equipment, light industrial products, video, cosmetics, agriculture and forestry machinery, ships, railway locomotives and products, motor vehicles and their parts and so on.
United States UL
UL is a global safety consulting and certification company headquartered in Northbrook, Illinois. It maintains offices in 46 countries. Established in 1894 as the Underwriters' Electrical Bureau (a bureau of the National Board of Fire Underwriters), it was known throughout the 20th century as Underwriters Laboratories and participated in the safety analysis of many of that century's innovative technologies.

UL is one of several companies approved to perform safety testing by the U.S. federal agency Occupational Safety and Health Administration (OSHA). OSHA maintains a list of approved testing laboratories, which are known as Nationally Recognized Testing Laboratories.[4]Listed in UL: Devices or devices used for complete replacement of products and qualified personnel on site. Such as: IT equipment, AV equipment, refrigerators, vacuum cleaners and other electrical equipment.

   UL Recognized: Recognized as a safety certification for components and materials. Such as: switches, power supplies, printed boards, transformers, wires, plugs, plastic materials.
   UL classification: A safety certification program that evaluates the performance of products used in commercial or industrial environments. Such as: building materials, various fire-fighting equipment and navigation equipment, chemicals.
   UL multiple listings: When a UL applicant obtains the listed, approved or tiered services listed above, its products must be produced on behalf of another company to meet the needs of sales, multiple listings can be applied, multiple approvals or multiple listings. Grading service. "AL" listed, approved or graded service. If the UL applicant does not wish to obtain listing, accreditation or grading services in the name of his own company, he may apply for listing, recognition or grading in the name of another firm (usually a retailer or wholesaler), ie "AL" Name, recognition or rating service. It differs from multiple listings, multiple accreditation, or multiple rating services in that its applicant is not a celebrity.

German VDE certification
VDE is the German Electrical Engineers Association, which was founded in 1893. One of the crucial functions of the association is the formulation of the German national industrial standard (DIN standard). The VDE Testing & Certification Institute is part of the Institute of Electrical Engineers, located in Offenbach, Germany, and was founded in 1920. As one of the most authoritative and professional testing and certification organizations in the world, VDE inspects and certifies electrical products according to DIN VDE standards or European EN standards, or IEC International Electrotechnical Commission standards. The VDE mark is the most authoritative certification mark in the field of electronics and electronics and is a symbol of quality. VDE has completed more than 18,000 certification projects each year for nearly 2,000 German companies and nearly 3,000 foreign customers. To date, 200,000 electrical products in nearly 50 countries worldwide have been awarded the VDE mark.
