The Research Institute of Building Materials (NIISM) was found as an independent economic organization on 01.01.1963. The main scientific departments are identified by construction industry branch subsections and are directed for developing of the relevant tasks. The mutual commitment among them gives an opportunity for solution of fundamental for the construction products industry problems.
In 1994 it was transformed according to the Commerce Law into NIISM Ltd with principal Ministry of Regional Development and Public Works.
Since 2002 on the base of Authorization ¹ ROSSP 04/12.11.2002 of the Ministry of Regional Development and Public works, NIISM has started to perform activities as a Body for construction products and FPC systems conformity assessment, Body for construction products testing in accordance with Ordinance on the material requirements towards constructions and evaluation of the construction products conformity (NSISOSSP). Authorization ¹ ROSSP 05/12.11.2002 of the Ministry of Regional Development and Public Works entitles NIISM to issue Bulgarian Technical Approvals .
Since 2007 NIISM holds new Authorizations for construction products conformity assessment in accordance with NSISOSSP-2006 and Construction Products Directive 89/106/E40 of Council of Europe respectively:
CPR 01 – NB 1950/30.02.2014 – forconstruction products and FPC systems conformity assessment under harmonized standards (part II of NSISOSSP) with identification number1950 of European Comission;
ROSSP - 03/17.09.2007 for construction products conformity assessment under part III of NSISOSSP (of products produced in compliance with BDS and non-harmonised EN).
ROSSP - 02/26.05. 2008 for BTA issue. NIISM has right to issue BTA for products produced in Bulgaria, for which there aren’t standards BDS and BDS EN.
In 2012 NIISM went through notification under the Construction Products Regulation (EU) No 305/2011 (CPR).
NIISM has been notified to European Comission under CPR (EU) No 305/2011 of EU Parliament and of European Council for determination of the harmonised conditions for marketing of construction products, covering all construction products from the Notifications.
