Rezumat: Noile instrumente pentru evaluarea echipamentelor neelectrice Ex constau dintr-o serie de proceduri specifice de evaluarea si de proceduri conexe de incercare. Seria procedurilor mentionate sunt elaborate in baza standardelor europene armonizate, adoptate in Romania si care include seria de standarde SR EN 13463 referitoare la „Echipamente neelectrice destinate utilizarii in atmosfere potential explozive”. Seria procedurilor mentionate sunt elaborate si implementate in cadrul organismului de certificare produse din cadrul INSEMEX-OEC, notificat la Bruxelles pentru Directiva ATEx. De asemenea procedurile de incercare sunt elaborate si implementate in cadrul laboratorului de incercari in atmosfere explozive LIEx. Noile instrumente pentru evaluarea echipamentelor neelectrice pot fi aplicate si in cazul echipamentelor miniere din grupa I, categoriile M1 si M2. Pana la aceasta data, INSEMEx Petrosani ca institut pentru securitate miniera si protectie antiexploziva a dezvoltat noi facilitati de incercare si evaluare pentru urmatoarele tipuri de protectie : - protectie prin carcase cu restrictie la curgere (fr); - protectie prin carcasa antideflagranta (d) ; - protectie prin securitate constructiva (c) .

Cuvinte cheie: echipamente neelectrice, evaluare, certificare, explozie, atmosfere explozive.

Abstract: The new instruments for assessment of non-electrical explosion protected equipment comprise a series of specific assessment procedures and the associated test procedures. The series of the above mentioned procedures had been carried out based upon the harmonized European standards adopted in Romania, that include the SR EN 13463 standard series regarding “Non electrical equipment for use in potentially explosive atmospheres”. The series of assessment procedures had been carried out and implemented within the product certification body in INSEMEX-OEC, notified at Brussels for the ATEX Directive. Also, the testing procedures had been elaborated and implemented within the Laboratory for Tests in Explosive Atmospheres – LIEx. The new instruments for assessment of non-electrical equipment may be applied to the mining equipment classified in Group I, Categories M1 and M2. Up to the present, INSEMEX Petrosani as an institute for safety in mines and explosion protection has developed new testing and assessment facilities for the following types of protection: - Protection by flow-restricting enclosure (fr); - Protection by flame-proof enclosure (d); -Protection by constructional safety (c).

Keywords: non-electrical equipment, assessment, certification, explosion, explosive atmosphere.
