Certification Testing

Certification Testing consists of two phases:

  • Alpha Testing: Laboratory testing to ensure the DAD meets all specifications and successfully communicates with and collects data from BAR simulators and/or in-use vehicles.
  • Beta Testing: Testing at participating California Smog Check stations to collect data from in-use vehicles.
