It covers a vast range of safety standards, including UL 60079 series, which align with global IEC standards for electrical equipment in explosive atmospheres. The National Electrical Code (NEC) in the United States also frequently references UL-certified products.
Certification Process
The ATEX certification process involves rigorous testing and documentation. Manufacturers must conduct a conformity assessment, submit a technical dossier to a notified body, and affix the CE marking along with the ATEX designation before products can be placed on the EU market.
In contrast, the UL certification process involves testing by a Nationally Recognized Testing Laboratory (NRTL), such as UL itself, to ensure compliance with specified standards. Products that pass the evaluation receive a UL mark, signifying adherence to safety requirements for hazardous locations.
Classification and Identification
ATEX uses a classification system that divides equipment into groups and categories based on risk levels and environmental factors. For example, Group I equipment is for mining applications, and Group II covers all other industries. Categories determine the degree of protection, with Category 1 being suitable for the most hazardous areas.
UL, while also classifying into groups and divisions, uses a different approach. It defines hazards in terms of Classes (such as Class I for gases, Class II for dust, and Class III for fibers), Divisions (indicating the likelihood of explosive atmospheres being present), and Groups (classifying specific materials). This system helps in specifying the protection required for different substances and environments.
Marking Differences
Each certification scheme has distinct marking requirements. ATEX markings include the Ex symbol, equipment group and category, and temperature class. For example, a typical ATEX marking might read II 1G Ex ia IIC T4 Ga, which provides detailed information about its applicable area and safety levels.
UL markings generally include the UL logo, specific class, division, and group codes. An example UL marking might be Class I, Division 1, Groups A, B, C, D, T4, indicating its suitable environments and hazard classes.
By understanding these critical differences in ATEX and UL certification schemes, companies and individuals operating in hazardous environments can make informed decisions on the appropriate equipment and safety standards needed for their specific applications.
