Conducting an Evaluation

Step 1: Completing the Protocol Information Conformance Statement

  • The EVSE vendor or manufacturer will need to complete the IEC 62443-4-2 Protocol Information Conformance Statement (PICS).
  • They will input the specific parameters of the EV charger, such as model number, firmware version, and manufacturer details.
  • They will fill in their responses to FR1-FR7 sheet in the Excel document.
  • This document will be shared with the authorized testing laboratory.

Step 2: Creating a New 62443-4-2 Test

  • Navigate to the ‘Certification Tests’ tab.
  • Select the ‘Create Certification Test’
  • Select IEC 62443-4-2 from the list of available standards.
  • Fill in the other information.
  • Click ‘OK’ to proceed.

Step 3: Running the Evaluation

  • Go to Certification Tests -> Tests -> Test Name in the Menu Bar.
  • The tool presents the option to run a series of tests to check compliance with IEC 62443-4-2. After each test is completed, it will indicate the location to save evidence of compliance.
  • Clicking on the Green triangle will run the tests.
  • Use the filters in the upper right to view specific categories such as 'Warning', 'Info', or 'Debug'.
  • Once complete, the tool will display a summary of the findings in an expandable form. Clicking the green R will open the results as an Excel sheet.

Viewing and Interpreting Results

Step 4: Reviewing the Results

  • Upon completion of the evaluation, navigate to the LabTest Results in Local APPDATA directory.
  • Review the high-level summary in the C:\Users\‘username’ \AppData\Local\LabTest\Results directory.
  • Review data in the subdirectories and add the associated evidence to these folders.
