Important notes
  • Make the target source and maintained/initial basis visible in the evidence record.
  • Tolerance comparison is planning support only and does not declare compliance with an Australian standard.

Formulas

  • \(\displaystyle \Delta E = E_{\mathrm{measured}} - E_{\mathrm{target}}\)
  • \(\displaystyle [E_{\min}, E_{\max}] = E_{\mathrm{target}} \times [1-t, 1+t]\)

Compare a measured illuminance value with a maintained or initial planning target and tolerance band.

Measured Lux vs Planning Target Checker is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
