In designing an automatic machine and any other instrument, the reliability of parts, especially the reliability of a motor, plays an important role.
And the use of standardized parts or components makes designing an manufacturing easy and reliable. Therefore, the countries throughout the world have their own established standards and legally put them in effect.

Domestic standards

KC(Korea Certification)

The Electrical Appliances Safety Control Act was amended in March 2009, simplifying 20 legal compulsory certification screening categories into 9 categories, and integrating 13 legal compulsory certification marks into KC (Korea Certification) mark, and thiswas implemented in July 2009. Safety (S), quality (Q), environment (E) and health (H) are marked next to KC mark additionally for each field of certification. It is possible to select between the previous K series standards and KS C IEC series standards for applied standards.

Japanese standards

PSE(Product , Safety, Electrical appliance & marerials)

These marks are required to be attached on an electrical appliance when safety is verified during inspection for short-circuiting and other malfunctions, according to the Act on Product Safety of Electrical Appliances and Materials, implemented in April 2001. Currently, these marks are managed by the Product Safety Office, Consumption Economy Division, Economic and Industrial Policy Bureau which falls under the Ministry of Economy Trade and Industry (METI). In the Act on Product Safety of Electrical Appliances and Materials, electrical appliances are categorized into specific electrical appliances, and other electrical appliances,which differs from specified electrical appliances. These specified electrical appliances are required to undergo conformity assessment by a certificate agency that meets the guidelines of the METI, and the PSE mark is diamond-shaped. Non-compulsory certification applies to other electrical appliances other than specific electrical appliances which includes the motor, and when the conformity has been certified under the necessity, a circular PSE mark is attached.

U.S. standards

UL(Underwriters Laboratories Inc)

Underwriters Laboratories Inc. is a non-profit corporation established by the American Fire Insurance Operators Association in 1894 and it is an inspection agency that has international authority. The UL mark is regulated for 1,400 target items including electronic/electric appliances, components, machines and equipment with the aimof minimizing physical injury of users, loss of lives and properties, and although it is a voluntary standard, not a forced standard,the credibility of UL in the U.S. is well-respected, and consumers show a high level of preference for this standard, so most manufacturers, dealers, and importers require this level of certification. Therefore, it is nearly the same as a mandatory standard. Standards related to the motor are as follows:

- UL - 73 : STANDARD FOR MOTOR - OPERATED APPLIANCES
- UL - 94 : TEST FOR FLAMMABILITY OF PLASTIC MATERALS
- UL - 507 : ELECTRIC FANS
- UL - 519 : IMPEDANCE PROTECTED MOTOR
- UL - 547 : THERMAL PROTECTED MOTOR
- UL - 674 : ELECTRIC MOTOR AND GENERATORS
- UL - 845 : MOTOR CONTROL CENTERS
- UL - 1004 : ELECTRIC MOTOR

Canadian standards

CSA(Canadian Standards Association)

CSA standards are established by the Electronic Industries Association of Canada andthe Canadian Standards Association is a private non-profit inspection agency. Any product, including electric appliances, components, gas and petroleum-based fuel appliances, and safety appliances, except for products certified by the CSA, cannot be used, or sold, in order to protect human lives and properties from fire and other accidents by law. The CSA provides standards for the inspection and requirements for checking the safety of such components. Also, CSA is tested as the Nationally Recognized Testing Laboratory (NRTL) by The United States Occupational Safety and Health Administration (OSHA), so if it is recognized that products conform with American safety standards, products carrying the CSA mark added with NRTL can be sold and used in the U.S.

- C22.2 NO. 77 : MOTOR WITH INHERENT OVERHEATING PROTECTION
- C22.2 NO.100 : MOTOR AND GENERATORS
- C22.2 NO.113 : FAN AND VENTILATORS

European standards

CE(Communaut Europeen)

A manufacturer who wishes to distribute, or sell products in Europe, should declare that such products conform with the relevant EU directives and attach the CE mark to the product earned via conformity assessment, such as model inspection, by the relevant notification agency (authorized agency, notified body). The attachment of a CE mark to a product means that the product, or its manufacturer, meets the essential requirements of EC regulations or directives. In other words, it means that the conformity assessment for such product was carried out by one of the manufacturers, importers, or third parties (certification agency) in order to distribute such a product to the market without any restrictions, and therefore, the CE mark should be attached to a product related to the health, safety and environment of a consumer, and a marked product can be distributed freely within the region of EUI and EFTA countries, without inspection or additional testing. Main EU directives are as shown below.

- Low voltage appliances(LVD) Low Voltage Directive 73/23/EEC
- Electromagnetic compatibility(EMCD) Electromagnetic Compatibility 89/336/EEC
- Machinery(MD) Machinery Directive 98/37/EC

Chinese standards

CCC(China Compulsory Certification)

This system requires products falling under the compulsory certification items among all products produced and distributed in China, all products and components exported to China to receive the safety and quality certification, and a product can be sold in the country only after receiving the CCC mark.
The quality and safety-related certification system in China was operated separatelyby applying a separate certification to products produced in the country, and imported products, but upon the entry into the WTO, the CCC mark certification system was implemented comprehensively starting on May 1, 2002. This is the safety and quality certification system that’s mainly for products including electric and electronic appliances, as well as automotive, and all items exported to China must receive the CCC mark from a Chinese certification agency in order to be exported, and companies that established a local factory in China can sell their products only after obtaining the CCC mark, instead of the previous CCEE mark.

International standards

IECEE/CB-Scheme

As the international certification system for the safety of electrical and electronic appliances, this is a specific mutual recognition system that enablesthe acquisitionof certification from the relevant country, without a duplicate test between 52 member countries, according to the IECEE/CB SCHEME.
IECEE (IEC System for Conformity Testing and Certification of Electrical Equipment) is the system established by merging the IEC and the CEE (European Commission for Conformity Testing of Electrical Equipment) in September 1985, and CEE which is the origin of this system was established in 1946, with the goal of promoting international trade by mutually certifying an electrical appliance tested by a testing agency of a member country in Europe, without testing it again, and IECEE has the advantage of simplifying the certification process of each country, that which is a technical barriers to non-tariff trade, and promotes trade between member countries while reducing the workload of testing agencies in each country. The extension of IECEE/CB-Scheme CB system will increase the exchange of information required for assisting manufacturers throughout the world that intend to obtain the certification, or approval, on each national scale, and the operation unit of the CB system is NCBs, and specified according to such principles. NCBs utilizes a testing lab called CBTL (CB Testing Lab) which is designated according to the rule.
