What is BS EN ISO 80079-27:2016?

In the field of hazardous areas and explosive atmospheres, safety standards play a crucial role in ensuring the protection of both personnel and equipment. One such standard that has gained prominence is BS EN ISO 80079-27:2016. In this article, we will delve into this technical standard to understand its significance and implications.

The Scope

BS EN ISO 80079-27:2016 focuses specifically on the design, selection, and construction requirements for electrical equipment used in explosive atmospheres. This standard aims to minimize the risk of ignition sources that could lead to an explosion in these hazardous areas.

Explosion Protection Concepts

This standard introduces several explosion protection concepts that are critical for preventing explosions in hazardous areas. These concepts include encapsulation, increased safety, intrinsic safety, and pressurization. Each concept has its own set of requirements and specifications, ensuring the equipment meets the necessary level of safety.

Equipment Groups and Categories

BS EN ISO 80079-27:2016 classifies electrical equipment based on their potential to create an ignition source and their level of protection against such hazards. The standard defines three Equipment Groups (Group I, Group II, and Group III) and three Categories (Categories M1, M2, and M3).

Group I comprises mines susceptible to firedamp, while Group II includes all other hazardous areas except mines. Group III encompasses explosive atmospheres occurring due to the presence of ignitable fibers or flammable flyings.

The Categories specify the equipment's suitability for use in specific environments. Category M1 represents equipment with a high level of protection for hazardous areas where continuous ignition sources are present. Category M2 offers a lower level of protection, and Category M3 is suitable for areas where the conditions are less severe.

Marking and Certification

BS EN ISO 80079-27:2016 also outlines the marking requirements for electrical equipment used in explosive atmospheres. Such equipment should bear the International Electrotechnical Commission's (IEC) Ex logo along with a unique identification code, indicating compliance with the relevant standards and regulations.

Certification plays a vital role in ensuring the equipment's conformity to BS EN ISO 80079-27:2016. Certified equipment assures safety and reliability, as it has undergone rigorous testing by an independent third-party certification body.

The Importance of Compliance

Compliance with BS EN ISO 80079-27:2016 is crucial for industries operating in hazardous areas. Stringent adherence to this standard ensures the safety of personnel, prevents accidents, and reduces the risk of explosions, which can lead to catastrophic consequences.

Additionally, compliance with this standard helps organizations to meet legal obligations and regulatory requirements. It provides a framework for the design, selection, and construction of electrical equipment, enhancing safety procedures and practices.

In conclusion, BS EN ISO 80079-27:2016 is a pivotal technical standard for electrical equipment used in explosive atmospheres. Its comprehensive approach towards explosion protection concepts, equipment classification, and marking requirements contribute significantly to mitigating risks in hazardous areas.

By complying with this standard, industries can ensure the safety of their personnel and infrastructure while demonstrating their commitment to operating in a responsible and compliant manner.
