Optics


The activity of the optics laboratory mainly focuses on three sectors:




 
The laboratory appears in the list of Notified Laboratories for CE marking regarding the following product standards:
  • EN 12368 “Traffic control equipment. Signal heads”
  • EN 12352 “Traffic control equipment.  Warning and safety light devices”.
  • EN 12966-1 “ Road vertical signs.  Variable message traffic signs. Part 1: Product standard.”
 
  •  EN 12899 “ Permanent road vertical signs “
In addition, the laboratory can carry out other testing:  photometric characterisation, goniophotometric and colorimetric vertical signs.
(EN 12899), Horizontal road marking materials (EN 1436), fari Headlights (IALA E 200 Recommendations)  and lamps and luminaires for road lighting (EN 13032).
 
Characterisation of building materials:
The laboratory carries out testing according to EN 410 for the determination of lighting characteristics and according to EN 673 for the calculation of thermal transmittance of glass for buildings for EC marking (e.g. glazing for insulation, glass layers).
 
Furthermore, the following tests to characterise the behaviour of materials exposed to solar and thermal radiation:
  • Solar and light characteristics of various materials (e.g. alveolar sheets, corrugated sheets, solar shields, film) according to EN 410 o ISO 9050
  • Light transmission of “Prefabricated accessories for roofing.  Individual roof lights for plastics” (testing for EC marking according to EN 1873).
  • Thermal and visual comfort of i nternal and external blinds according to EN 14501.
  • HAZE measure ( hazing ) according to the ASTM D 1003 regulation on transparent materials, for example glass; 
  • Determination of the protection factor UPF to UV rays according to the AS/NZS 4399/199;
  • Colour and colour difference of coloured surfaces (e.g. paints) according to UNI 8941.
  • Paints for tanks (evaluation of requirements of European Directive 94/63 regarding the control of airborne organic compost emissions derived from petrol deposits and their distribution from petrol stationgarage terminals.
  • Solar reflection index (SRI) (for LEED certification) of outside flooring materials and flat coverings) 
  • Determination of Ug, SHGC, SC and VT coefficients according to NFRC (ASHRAE 90.01-2007) regulations;
  • Hemispheric emission measurement according to ASTM C 1371.
  • Normal emission measurement of specular samples (e.g. coating on glazing) according to EN 12898.
  • Thermal transmittance of insulating windows with theoretical method according to UNI EN 673 regulation, based upon emissivity measure and the Argon gas concentration.
 
On-site testing:
  • Verification of road lighting equipment (UNI 11248).
  • Measurement of the light factor during daylight hours.
  • Lighting engineering surveys for verification of illumination levels in the workplace.
