ISO 14001:2004 for the following activities

csq-ecoArditi products are compliant with the ruling European Standards (EN) and international Standards (where existing). Such conformity is certified by CE certification (where applicable), that is compulsory according to the law, as well as by non compulsory quality marks issued by the most prestigious International Certification Authorities like, for example, the followings: ENEC, IMQ, VDE, BSI, LCIE, UL, SEMKO, etc.

The lampholder falls within the category of electric products and as such must comply with the legal provisions and the technical standards that aim mainly at guaranteeing safety during normal use of such products. All the electrical material (except plug outlets for household use) with a rated voltage from 50V to 1000V a.c. and from 75V to 1500V d.c. is subject to EEC Low-Voltage Directive 73/23 amended by EEC directive 93/68 of the European Community Council and implemented, respectively, by the Italian legislation with law no. 791 of 1977 and with D.L. no. 626 of 25 Nov. 1996 amended by D.L. no. 277 of 31 July 1997.

The Low-Voltage Directive requires the manufacturer to put electrical material on the market that is built in conformity to professional rules regarding safety. EEC directive 93/68, whose objective is to overcome the obstacles to free circulation of products in EU countries, introduced the following new parts concerning the application of the Low-Voltage Directive: the manufacturer or his agent in the EU must affix the CE mark on the product or, when not possible, on the packing, on the use warnings, on the warranty certificate; the manufacturer must prepare the technical documentation to be used to evaluate whether the product conforms to requirements of the directive; the manufacturer or his agent in the EU must draft a conformity declaration to be kept together with the technical documentation; the manufacturer must have a fabrication process control system;


Therefore, the CE mark, which is mandatory, has mainly a legal value. In fact, it is designed to reassure the public authorities of the community countries that the legal obligations have been satisfied.
A product whose quality exceeds the minimum requested by community laws is identified by a voluntary quality mark granted by an external institution such as the Italian Quality Mark Institute (IMQ) that has been operating in Italy since 1951. A quality mark certifies that the product conforms to national and international standards. The main reference norms for the production of lighting fixture components are:

– EN 60238 for Edison screw lampholders (E14, E27, E40);
– EN 61184 for bayonet cap lampholders (B15, B22);
– EN 60838 for lampholders for halogen and discharge light sources;
– EN 60400 for lampholders for fluorescent light sources;
– EN 50075 for, two-pole 2.5A 250 V plugs.

In June 1992, an agreement was reached (LUM agreement) that called for a unified market for lighting fixtures starting in 1993. The new mark, called ENEC, European Norms Electrical Certification, certifies that a product conforms to the harmonised European standards (the EN standards). The ENEC mark is currently recognised as equivalent to the national mark by the certification organisations: AENOR (Spain), CEBEC (Belgium), IMQ (Italy), CERTIF (Portugal), KEMA (The Netherlands), NSAI (Ireland), SNCH (Luxembourg), LCIE (France), ELOT (Greece), VDE (Germany), OVE (Austria), BSI (United Kingdom), SEV (Switzerland), SEMKO (Sweden), DEMKO (Denmark), FIMKO (Finland ), NEMKO (Norway), MEEI (Hungary), BEAB and ASTA (England), EZU (Czech Republic), SIQ (Slovenia), TUV-Rheinland, TUV-PS.
The number next to the ENEC mark identifies the certification institution that issues the ENEC mark. For the IMQ the number is 03.
The procedure to obtain the ENEC mark involves approval of the manufacturer, who must have a quality system that conforms to the EN ISO 9002 standards, product approval and production monitoring.
