ISQ has its own Laboratory of Electric Cables (accredited laboratory) for assessment of compliance with legal requirements, standards and specifications.

About this service:

ISQ has its own Laboratory of Electric Cables (accredited laboratory) for assessment of compliance with legal requirements, standards and specifications. ISQ conducts projects of cable testing for certification by third part. This process may involve a product certification body.   ISQ has agreements with the Certification Body CERTIF (Association for the Certification) for swifter certification process which issue the licenses based in the ISQ test reports. ISQ cable laboratory is accepted to operate as laboratory in the HAR Scheme and CB Scheme with CERTIF as Certification Body. Cables with improved characteristics Testing to monitoring and support to manufacturers in the validation of electric cables with improved characteristics, through the performance of the following tests listed below: Burning behaviour testing Testing to determine halogens, corrosiveness of emitted gases Saponification testing Testing to determine carbon black Testing resistance to ozone Ageing tests when before different type of agents (temperature, solar radiation, UV radiation, chemical agents) Thermal stability of constituent materials Toxicity índex Electric power cables Assessment of compliance with the functional characteristics, safety and durability, thereby meeting storage, transportation, installation and use requirements, as set down in standards or contractual documents. Tests of electric energy cables of low voltage up to and including 450 V / 750 V- sets of standards: EN 50525; IEC 60227; IEC 60245 Testing of power cables – series of IEC 60502 standards Testing cables for motor vehicles – ISO 6722; ISO 14572 Cables for electric installations in ships according to IEC 60092-xxx series standards Railway rolling stock power and control cables according to EN 50264, EN 50382 and EN 50355 series Examples of tests Long duration testing of medium voltage cables (two years) Testing resistance under bad weather conditions (solar radiation, UV, thermal shock, rain, etc.) Testing fire behaviour Testing to determine halogens and corrosiveness of emitted gases Saponification testing Testing to determination carbon black Testing resistance to ozone Electrical testing (shockwave 1.2/50ms, industrial frequency voltage, ohmic resistance) Ageing tests when before to different type of agents (temperature, solar radiation, UV radiation, chemical agents) Testing resistance of several types of mechanical actions (flection, shock, bending, stretching, insulation piercing) Thermal stability of constituent materials Testing the quality of cluster settings of cable terminals Water absorption Testing to determine dimensions (thickness, diameters, etc.) Telecommunications and data communications cables Assess compliance of telecommunication and data communication cables with the regulatory standards in force. Testing coaxial cables – series of EN 50117 standard Testing data communication cables
