Technical requirements for entries in flameproof enclosures operating in potentially explosive atmospheres

Abstract

The evaluation of explosion-proof electrical equipment for certification is particularly important given the risk of explosion and must be minimized. This in order to ensure the safety of life, health of workers, to prevent damage to goods and the environment when they meet the essential security requirements at European level. Directive 2014/34 / EU states that equipment used in explosive atmospheres must be designed to operate without endangering the environment for which it is intended. This paper proposes the study and evaluation of the requirements for flameproof enclosures. In order to verify explosion protection, the representative samples made available by explosion-protected equipment manufacturers are tested under the worst possible conditions that may occur in practice.
