Equipment & Standards

Why use standards

Following common practices on manufacturing, calibrating and using test equipment, as specified by national and international Standards Organizations allows easier intercomparison of measurement results performed in different laboratories. Abet Technologies’ systems are constructed to allow standards compliant metrology.

The following is a sampling of the standards, current as of the publication date of this catalog. These are the standards we refer to when specifying that our products are standards compliant:

  • ASTM E927-10 Standard Specification for Solar Simulation for Photovoltaic Testing
  • ASTM E948-09 Standard Test Method for Electrical Performance of Photovoltaic Cells Using Reference Cells Under Simulated Sunlight

Solar Simulator standards

The currently applicable standards are quite similar but not identical. The ASTM, IEC and JIS requirements for different solar simulator classifications are as follows:


All Abet Solar Simulators are shipped with a Certificate attesting it has been tested to and meets or exceeds all  applicable class standards.
