Pirform Release 2025.3: Ring Circuits & SPD Reporting

This release brings improvements and fixes to Pirform. The highlights include:

  • Pirform's cable sizing intelligence now includes the on-site guidance for ring final circuits.
  • Improvements to SPD reporting.
  • Easier adding of images to observations.
  • Numerous other improvements and fixes.

Return of the ring

We have brought back the previous method of handling ring final circuits to Pirform's intelligence, which follows the guidance set out in the IET's On-Site Guide.

In versions from 2025.3 onwards you can tell Pirform that the circuit is a ring final circuit simply by entering the word "ring" in the circuit designation. Pirform intelligence will use the relevant guidance to determine whether the circuit is correctly sized.

Dragging observation images

You can now easily add images to the selected observation by dragging and dropping them from your computer. Simples!

Improved SPD reporting

We have improved the way that SPD (surge protective device) information is entered and reported in Pirform. You can now report SPD status as CONFIRMED, FAIL, or NOT APPLICABLE (N/A).

Use keyboard shortcuts to speed up data entry

You can use Pirform's keyboard shorcuts to speed up data entry. More details in our documentation here.

SPD status values in Pirform

When reporting the SPD is not applicable, you now only have to enter that once:

Reporting N/A for SPD

But it will still be reported in both the board details and test results in the certificate PDF:

Reporting N/A for SPD in the PDF in board details

Reporting N/A for SPD in the PDF in test results

Lastly, when reporting a failure for the SPD, Pirform has intelligence that automatically adds an observation to report the failure, coding it as a C3:

Reporting FAIL for SPD

Observation showing FAIL for SPD

Improvements to form sizing

We have improved the way Pirform detects the screen size when it opens, particularly when on smaller screens.

Circuit counts in PDF

The circuit counts in the PDF now ignore spare circuits.

Other changes and fixes

Other changes and fixes available in this version include:

  • Change: now populates the Zdb value when creating a new MW from an existing circuit.
  • Change: improved handling of manually entered max Zs values.
  • Change: improved image handling by preventing 'in use elsewhere' exceptions.
  • Change: new lookup controls used for multi-column values (e.g. BS (EN) values).

  • Change: more improvements to Pirform automatic repair feature.

  • Fix: now recreates missing instruments when loading company files. Fix: intelligence observations codings were not always applied.

  • Fix: max Zs calculations for 61009 systems in TT installations now reference the RCD residual current.
  • Fix: error when creating a new cert without an engineer.
  • Fix: automatic repair now repairs circuit RCD BS values.
  • Fix: auto-repair corrects schedule items and observations marked as intelligence managed that have no associated intelligence.
  • Fix: automatic repairs are now carried out when importing from a specific file.
  • Fix: was not saving some certificate settings, such as excluding NA schedule items from the printed PDF.
  • Fix: engineer control was not correctly positioned when first shown.
  • Fix: was not respecting start-maximised setting.
