Safety Standard

	KS Mark (Korean Industrial Standards) KS means Korean Industrial Standards, established as National Standards through examination and deliberation of Industrial Standard Deliberation Committee, based on Industrial Standardization Law announced in Sep. 30, 1961. This defines technical terms, codes, dimension, type, shape, test, analysis, inspection method, design, materials, production and packing method etc. and the standard related to electrical section shall be marked as KSC. The standard for motor is as follows Method of characteristic calculation for 3 phase induction motor Low pressure 3 phase induction motor for general purpose High pressure 3 phase induction motor for general purpose Single phase induction motor for general purpose Starting class of induction motor
	JIS (Japanese Industrial Standards) JIS is Japanese Industrial Standards, established as National Standards by deliberation of Japanese Industrial Standard Committee which was organized by all experts based on Standardized Law. General Principle of Revolving Electric Machine High pressure (3000V) 3 phase induction motor Single phase induction motor for general purpose Starting class of induction motor Method of characteristic calculation for 3 phase induction motor Low pressure 3 phase cage type induction motor for general purpose Low pressure 3 phase induction machine Principle of general explosion-proof structure of electrical machine General explosion-proof structure of electric power machine
	CCC (China Compulsory Certification) CCC is the certification system for quality safety, executed from August 2003 in China. Before joining the WTO, China has implemented the binary policy that the certification system related to quality and safety is applied separately for the domestic products and the imported products. However, according to the comments that it is giving preference to the people of China, China integrated CCEE (China Certification for the Safety of Domestic Products) and CCIB (China Certification for the Safety of Imported Products) as one certification system of CCC for the improvement of certification system since May 1, 2002 and later put CCC certification system into force since August 2003 after having a grace period. The manufacturers who produce the corresponding product in China or who export to China are required to obtain CCC mark and if failed to obtain a certificate, the products are not allowed for customs as well as charged maximum 4.8 million KRW for penalty.
	RoHS (The Restriction of the use of certain Hazardous Substances in electrical and electronic equipment) This is a regulation for the restriction for the use of certain Hazardous Substances in manufacturing electrical and electronic equipment and an environmental regulation set in force by EU. 6 certain hazardous substances include lead (Pb), Cadmium (Cd), mercury (Hg), Chrome (Cr6+), PBBs(Polybrominated phenyls), and PBDEs(Polybrominated diphenyl ethers).
	UL (Underwriters Laboratories Inc) This is non-profit foundation established by the Union of USA Fire Underwriters Laboratories in 1894 and the world authoritative inspection institute who works for test research and certification for the safety of machine, instrument or materials in order to protect the life of personnel and properties from fire or other accidents. The range of certification is limited to the general purpose such as electronic application machine, motor application machine, electronic parts etc but in most states of USA, the products are not allowed to sell without UL certification and even if the sales are allowed, if the fire breaks out due to the product without UL certificate, USA Fire Underwriter Laboratories shall not be responsible for that. Thus, as the consumers purchase only the products with UL certificates, the products having obtained UL certificate are distributed in USA. In addition, recently, UL was acknowledged as certification institution or test institution by SCC (Standard Council of Canada) and authorized from all states of Canada. When requesting a UL, if you request a SCC together and receive the test result ‘PASS’, you can attach c-UL to distribute in USA and CANADA at the same time. 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
	CSA (Canadian Standards Association) This standard was established by Electric Association of Canada and for electric equipment, electric parts, GAS, petroleum fuel equipment, safety instruments etc, it is not allowed to sell except for the products with CSA mark in order to protect the life of personnel and properties from fire or other accidents. Thus CSA defines the standard as requirements of inspection to verify the safety of these parts. In addition, as CSA is acknowledged as NRTL (Nationally Recognized Test Laboratories) by OSHA (Occupation Safety Health Association) of USA, if it is recognized as suitable for safety standard of USA, it is allowed to sell and use in USA by attaching the NRTL added mark to CSA mark. 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 the product safety mark obligated for the products which are distributed in EU and this mark is allowed only for the products suitable for the safety principles directed by EC Directive. The purpose of CE mark is to unify the safety principles per country and distribute the safety assured products smoothly, and by adjusting and unifying the safety principles for machine, medical instruments, toys, pressurized container etc per product, the unified principles are delivered as orders. For example, for industrial robot, the obligation to meet the orders related to machine until January 1995, the orders related to EMC (Electromagnetic Conformity) until January 1996 and the orders related to low voltage until 1997 shall be generated.
	EN STANDARD In the area of EU, the efforts to unify the industrial standard and safety standard of each country are being in process and CEN (European Committee for Standardization) and CENELEC (European Committee for Electrotechnical Standardization) are leading its role. The unified standard is called ‘HARMONIZED STANDARD’ and EN is attached in the front digit of standard number. In case of exporting to EU area, EN standard is based on the design and manufacturing but in case not yet established by EN standard, IEC and VDE are applied and when tested by civil certification institution such as TÜV Rheinland. If passed, each safety mark can be used for the products by inspecting from certificate authorities such as VDE and get approved.
	DIN (Deutsches Institut für Normung) DIN is the standard established by German Standardization Committee and for E Class motors of Korea, this standard is applied.
	ISO-9000 This is an international standard based on BS 5750 and ANSI Z 1,15 of UK and a system that ISO (International Standardization Organization) evaluates general quality system of supplier who provides the product or service to consumers and acknowledges the quality assurance capability based on ISO-9000 established in 1987.
	IEC (International Electrotechnical Commision Publications) IEC covers the part related to motor directly such as insulation, system of attached dimension, shaft system etc as well as general and wide range of electric and mechanic. That is, this is designed to be used properly with the standard in actual operation and currently JIS or KS of motor is also defined based on IEC dimension.
