Korean Industrial Standards
KS (Korean Industrial Standards) was established as national standards through investigation and deliberation by the Industrial Standards Deliberation Committee in accordance with the Industrial Standardization Act promulgated on September 30, 1961. KS stipulates the technical terms, symbols, dimensions, types, shapes, tests, analyses, inspection methods, designs, materials, production, packaging methods, etc. Standards related to the electrical sector are indicated as KSC. The specifications related to the motor are as follows.
  • KSC-4201: Method for estimating the characteristics of a 3-phase induction motor
  • KSC-4202: Low-voltage 3-phase induction motor for general purposes
  • KSC-4203: High-voltage 3-phase induction motor for general purposes
  • KSC-4204: Single-phase induction motor for general purposes
  • KSC-4205: Starting class of the induction motor
Japanese Industrial Standards
JIS (Japanese Industrial Standards) is the national standard established through deliberation by the Japanese Industrial Standards Committee (JISC), which is organized based on the Standardization Act and composed of authorities from all over the country. The secretariat of the JISC includes the Standards Bureau of the National Institute of Industrial Science and Technology under the Japanese Ministry of International Trade & Industry.
  • JISC - 4004: General Rules For Rotating Electrical Machines

China Compulsory Certification
CCC is a certification system related to quality and safety that has been implemented in China since August 2003. Before joining the WTO, China had implemented a policy of applying different quality and safety certification systems to imported products and products for domestic consumption. However, this policy drew flak for favoring only its own citizens, so the Chinese government improved its certification system after joining the WTO. The Chinese government integrated the CCEE (Conformity Certification of Electrical Equipment) applied to domestically produced products and the CCIB (China Commodity Inspection Bureau) certification granted to imported products into a single certification system—CCC—starting May 1, 2002. After a grace period, the CCC certification system was fully implemented in August 2003. Companies producing or exporting the relevant items in China must obtain the CCC mark. If a manufacturer fails to obtain certification, the product will not be cleared through customs and a fine of up to 4.8 million won can be imposed.
RoHS (The Restriction of the use of certain Hazardous Substances in electrical and electronic equipment)
This is a regulation restricting the use of specific hazardous substances when manufacturing electrical and electronic products. As an environmental regulation implemented by the European Union, it restricts the use of six specific hazardous substances in electrical and electronic products: lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), PBBs (polybrominated phenyls), and PBDEs (polybrominated diphenyl ethers).
Underwriters Laboratories Inc
Established in 1894 by the American Fire Insurance Association, this non-profit foundation is a globally authoritative testing organization that tests, researches, inspects, and certifies the safety of machinery, equipment, and materials to protect people and property from fire and other accidents. The scope of certification is limited to general-purpose products such as electronic applications, electrical applications, and electronic components. In most states in the US, however, products cannot be sold without UL certification. Even if sales are permitted, consumers purchase UL-certified products on their own because of regulations stating that American fire insurers are not responsible for fires caused by products without UL certification. Therefore, most products sold in the US have UL certification. These days, it is also recognized as a certification and testing agency by the Standards Council of Canada (SCC) in Canada, so it is recognized by all provinces in Canada. If the Canadian safety standards are also applied when applying for UL certification, the product can be sold in both US and Canada with c-UL attached if the test results are recognized as satisfactory.
  • UL - 50: ENCLOSURES FOR ELECTRICAL EQUIPMENT
  • UL - 73: STANDARD FOR MOTOR - OPERATED APPLIANCES
  • UL - 94: TEST FOR FLAMMABILITY OF PLASTIC MATERIALS
  • UL - 507: ELECTRIC FANS
  • UL - 519: IMPEDANCE PROTECTED MOTOR
  • UL - 547: THERMAL PROTECTED MOTOR
  • UL - 674: ELECTRIC MOTORS AND GENERATORS
  • UL - 845: MOTOR CONTROL CENTERS
  • UL - 1004: ELECTRIC MOTOR
  • UL - 1446: SYSTEM OF INSULATING MATERIALS - GENERAL
  • UL - 1692: POLYMERIC MATERIALS - COIL FORMS
Canadian Standards Association
CSA Standards is a law established by the Canadian Electrical Manufacturers Association. In order to protect people and property from fire and other accidents, electrical equipment, electrical parts, gas, petroleum fuel equipment, and safety devices other than those certified by CSA are prohibited from being used or sold. CSA Standards stipulate inspections and requirements to check the safety of these products. In addition, since CSA has been certified by the Occupational Safety and Health Administration (OSHA) as a Nationally Recognized Testing Laboratory (NRTL), if it is recognized as satisfying US safety standards, the NRTL mark can be added to the CSA mark, and the certified product can be sold and used in the US.
  • C22.2 NO. 77 : MOTORS WITH INHERENT OVERHEATING PROTECTION
  • C22.2 NO.100 : MOTORS AND GENERATORS
  • C22.2 NO.113 : FAN AND VENTILATORS
CE Marking
This is a product safety mark that must be attached to products distributed within the European Union (EU). This mark can be attached to products that comply with the safety regulations of the European Community Council Directive. The CE mark aims to unify safety regulations by country and to facilitate the smooth distribution of products with guaranteed safety. It issues directives that adjust and unify safety regulations by product sectors such as machinery, medical devices, toys, and pressure vessels. For example, industrial robots are required to comply with the machinery-related directives by January 1995, electromagnetic compatibility (EMC)-related directives by January 1996, and low voltage-related directives by 1997 in that order.
EN STANDARD
Within the EU, the work of unifying industrial and safety standards among each country is being led by the European Committee for Standardization (CEN) and the European Committee for Electrotechnical Standardization (CENELEC). The unified standards are called harmonized European standards and are preceded by EN in the standard number. When exporting to the EU region, EN standards are the basic requirements for design and manufacturing. If the applicable EN standards have not yet been established, however, IEC and VDE standards are applied; if they are inspected by private certification agencies such as TÜV Rheinland and VDE and are recognized as compliant with the standards, each safety mark can be displayed on the product.
DIN (Deutsches Institut für Normung)
The DIN standard is a standard established by the German Standards Committee, and many of its provisions are applied as they are to the standards for Korea's E-class motors.
ISO-9000 standard
An international standard established based on BS 5750 and ANSI Z,1,15 of the UK. It is a system that evaluates the overall quality system of suppliers providing products or services to consumers based on the ISO-9000 standard established by the International Organization for Standardization (ISO) in 1987 and certifies quality assurance capabilities internationally.
International Electrotechnical Commision Publications
IEC’s international recommended standards cover not only areas directly related to motors (insulation, series of mounting dimensions, shaft series, etc.) but also general and broad fields (electricity, machinery, etc.). In other words, it is stipulated that the standards should be used appropriately when actually operated, and the current JIS standards and KS standards for motors are also stipulated based on IEC standard dimensions.
