Introduction

There are many considerations when selecting a switch to be used in

hazardous areas. In addition to switch performance, it’s important to

understand the country of use, as well as the approvals each switch

carries. This selection guide will help to define Hazardous Area Approvals

and Markings for both North American and Global applications, as well as

define the approvals MICRO SWITCH Hazardous Area Switches carry.

For assistance with selecting a hazardous area switch, please contact

Honeywell’s product team at +1-815-235-6847, info.sc@honeywell.com,

or your Honeywell distributor.

Global Approval Descriptions

Mark Country Approval Description

North AmericaUL Mark means UL has tested representative samples of the product and determined the product meets the requirements of UL. These requirements are based primarily on published and nationally recognized Standards for Safety.

� North America

The CSA mark demonstrates that a sample of the product has been certified to applicable standards including standards written or administered by the American National Standards Institute (ANSI), Underwriters Laboratories (UL), CSA Group (CSA), NSF International (NSF), and other North American and global organizations.

United States and Canada

The cULus mark certifies the equipment was evaluated to Canadian and US standards by Un-derwriters’ Laboratories. The combination mark indicates compliance with both Canadian and U.S. Requirements. “Listed” means that the product can be operated as sold, in accordance with its inscriptions and operating instructions, without retesting by UL. Products are for use in hazardous locations where explosive atmospheres may be present. Certification covers division and zone area classification systems for the United States and/or Canada.

EuropeThe Ex mark is a statement from an independent Notified Body verifying compliance with the requirements of the European standards that are harmonised with the 94/9/EC Directive (ATEX Directive, named after the French “ATmosphere EXplosible”).

Global

The IEC Ex mark means the equipment complies with the requirements of the International Electrotechnical Commission Explosive. The objective of the IECEx system is to facilitate inter-national trade in equipment and services for use in explosive atmospheres, while maintaining the required level of safety.

EuropeNotified Body. For equipment used in the European Union in accordance with the R&TTE Directive, the CE Mark and the notified body (NB) identification number is used when the NB is involved in the conformity assessment procedure.

EurAsian Conformity

Products certified are labelled with Customs Union Mark of Conformity, called EurAsian Conformity Mark – EAC, before they are placed on the market of the Customs Union member states (Russia, Belarus and Kazakhstan).

Korea

Korea’s “Electrical Communication Basic Law,” requires EMC testing and certification for many electronic products. Korean EMC certifications are issued by National Radio Research Agency (RRA), which is organized under the Korea Communications Commission (KCC). EMC testing includes electromagnetic interference (EMI) and susceptibility (EMS). Certified equipment is labeled with the KC mark and certification number.

China

NEPSI is an international testing laboratory accredited by IECEx Scheme, Shanghai Inspection and Testing Center of Electrical Equipment for use in Explosive Atmospheres for National Work Safety authorized by China State Administration of Work Safety (with qualification of Class A). NEPSI runs strictly in accordance with ISO/IEC 17025 and ISO/IEC 17020.

BrazilBrazil’s IN METRO (Institute of Metrology, Standardisation and Industrial Quality) is the gov-ernment body responsible for the implementation of measurement, safety and quality stan-dards for electrical and electronic products.
