Introduction Introduction For many decades, NORD DRIVESYSTEMS has supplied drive units for use in potentially explosive environments. Since 2003 this range has also included specially designed gear units which comply with EU Ex directives (ATEX). Over the past years a great deal of work has been invested in order to comply with other international regulations such as IEC Ex, EAC Ex, CCC Ex, UKEX as well as the specifications for the North American market. With a new generation of motors NORD is responding to the stricter efficiency requirements in Europe and China. These motors for dust explosion...

Specific national regulations DRIVESYSTEMS Scope of Application Basis European Union „ATEX“ For many decades, the EU has been using the ATEX technical standards to ensure the safe operation of machinery and equipment. With its Ex specifications for mechanical devices regarding the former Directive 94/9/EG the EU acted as a pioneer at that time. EU member states + others such as Norway and Switzerland Technical standards based on IEC standards (IEC - International Electrotechnical Commission) Directive 2014/34/EU relates to mechanical and electrical devices for use in explosion hazard areas. (In...

Specific national regulations IEC Ex Introduction IEC Ex approval can be helpful for the approval of explosion protected electrical equipment according to national standards. Technical standards based on IEC standards (International Electrotechnical Commission) IEC Ex 01 IEC Scheme for the Certification to Standards for Electrical Equipment for „Explosive Atmospheres (IEC Ex Scheme) - Basic Rules“ und IEC Ex 02 IEC Scheme for the Certification to Standards for Electrical Equipment for „Explosive Atmospheres (IEC Ex Scheme) - Rules of Procedure“ IEC 60079-0 - Part 0: Explosive atmospheres Equipment...

Specific national regulations DRIVESYSTEMS CertifiedNORD-Products EAC Ex EAC (abbreviation for EurAsian Conformity) is a label which states that a product complies with the specifications of the Eurasian Economic Union regarding technical specification, labelling and documentation. EAC Ex indicated conformity with the standard TR CU 012/2011 1) „On safety of equipment intended for use in Explosive atmospheres". This contains technical specifications which are largely based on the IEC Ex as well as standards which are used in the EU. Due to expiring certificates, the delivery of EAC Ex-compliant...

Specific national regulationsCanada CEC Introduction Scope of Application Basic National Electrical Code ► With the 2015 version of the Canadian Electrical Code (CEC) the IEC concept based on Zones was adopted: ^ A5, IEC Ex - Repairs and extensions of existing systems may continue to be carried out in accordance with the requirements of the division system. ^ C3 A8, HazLoc Canadian Electrical Code ► Article 18-000, Annex J (see also NEC 500)

Specific national regulations Class I - Gas groups A, B, C and D ► Gases, vapours or aerosols Areas in which hazardous concentrations of flammable gases or vapours - Can be present under normal operating conditions, - Can frequently occur during repair and maintenance work, - Can occur throughout malfunctions concerning operation. During which, errors occurring in electrical equipment may result in a source of ignition. - Areas in which hazardous concentration of flammable gases or vapours are kept in closed containers or systems and can only be released under fault conditions. Class II - Dust...

Comparison of IEC and US explosion protection Zone 20 is an area in which ignitable concentrations or combustible gases aerosols or liquids - Probably occur during normal operating conditions - Regularly occur as a result of maintenance or repair work or due to frequent faults. is an area in which ignitable concentrations of combustible gases, aerosols or liquids - Probably do not occur during normal operating conditions - Normally occur in closed containers and which can only be released in case of accidents, faults or abnormal operation.

Specific national regulationsNote Despite of the same syntax, the US temperature classes differ from those which are used by IEC: Energy efficient Motors For motors, the following specifications apply with regard to energy efficiency classes: ► USA Regulation: Epact 2007 EISA (NEMA MG-1) ► Canada Regulation: CSA C390 (NEMA MG-1) ► Official body involved:

■ Specific national BB regulations CCC Ex Certified NORD products Scope of Application Basic Energy efficiency Since 1.10.2020, all motors in China which are suitable for use in potentially explosive applications are subject to CCC Ex certification. This applies to motors that are imported to China as well as to motors that are put into operation in China. The regulation applies to both gas and dust explosion protection and all Zones. CNCA-C23-01:2024 - Compulsory Certification Rules - explosion protected electrical equipment (also called ,CCC Ex‘). NORD CCC Ex motors have been certified for...
