What is BS EN ISO 80079-27:2016?

BS EN ISO 80079-27:2016 is an international standard that provides guidelines for the selection, installation, inspection, and maintenance of electrical equipment used in potentially explosive atmospheres. This technical article aims to explain the key aspects of this standard in a simplified and easy-to-understand manner.

Scope and Application

The scope of BS EN ISO 80079-27:2016 covers equipment intended for use in environments where flammable gases, vapors, mists, or combustible dusts may be present. It applies to both electrical apparatus and associated equipment such as cables, glands, and sealing fittings used in hazardous locations.

Key Requirements

The standard mandates that all equipment used in explosive atmospheres must undergo rigorous testing, certification, and marking processes. Manufacturers are required to ensure that their products meet specific criteria for temperature rating, ignition protection, electrostatic discharge resistance, and other safety parameters.

Furthermore, BS EN ISO 80079-27:2016 emphasizes proper installation practices to prevent potential ignition sources and mitigate explosion risks. It specifies guidelines for cable entry devices, barrier glands, and sealing techniques, which help maintain the integrity of the hazardous location enclosure.

Maintenance and Inspection

Regular maintenance and inspection are crucial to ensure ongoing compliance with BS EN ISO 80079-27:2016. The standard provides recommendations for routine inspections, including visual checks, functional tests, and assessments of protective measures. Equipment should be inspected by competent personnel at specified intervals, and any defects or non-compliance identified should be rectified promptly.

In conclusion, BS EN ISO 80079-27:2016 is an essential standard that ensures the safety of electrical equipment used in potentially explosive atmospheres. Its guidelines cover various aspects such as equipment selection, installation best practices, maintenance requirements, and inspection procedures. Adhering to this standard helps mitigate the risks associated with flammable gases, vapors, mists, and combustible dusts, ultimately safeguarding workers and preventing accidents.
