IEC 62305:2024 Risk Assessment Software
Lumex is cloud lightning risk assessment software for IEC 62305: a real Part 2 risk engine that computes your lightning risk against the tolerable limit, plus the frequency of damage to internal systems, from the standard's own coefficients, traceable to every input, and turns the result into a branded, audit-ready report. It is purpose-built risk assessment software for the current 2024 third edition, in the browser, for your whole team.
Lumex is software for the IEC 62305 lightning risk assessment. It runs the full IEC 62305-2 risk method in the browser: you model the structure, its surroundings and the services connected to it, and the engine resolves your lightning risk against the tolerable limit, plus the frequency of damage to internal systems, building it from all nine risk components straight from the standard's coefficients.
It is built on the published current 2024 third edition, adopted nationally across most of the world, so the method behind every number is the one an auditor or authority cites today. New to the standard itself? Start with what IEC 62305 is, then read on for what the software does.
A real IEC 62305 engine, not an estimator
Lumex computes the assessment in full and shows its working, then turns it into the document you file.
The full risk computation
Collection areas, dangerous-event rates, damage probabilities and loss factors, computed from the IEC 62305-2 coefficients and rolled into all nine risk components, with your lightning risk judged against the tolerable limit and the frequency of damage to internal systems assessed alongside it. See how a risk is calculated.
Traceable to every input
Each result carries the full coefficient trace behind it, so the number your engineer signs can be defended clause by clause, never an opaque black box. More on traceable risk assessment.
Branded, audit-ready reports
One assessment produces a PDF with the structure model, methodology, per-zone results and a sign-off block, carrying your firm's branding. See what makes an audit-ready report.
Inspection and the whole team
A periodic LPS inspection record per IEC 62305-3, plus team workspaces where a project holds many sites, each with its own zones, report and revision history.
Why not a spreadsheet or a desktop tool
A spreadsheet hides its assumptions and drifts out of step with the standard. A desktop tool ties the work to one machine and one licence. Software in the browser removes both, and ends the assessment in a report you can file, not a raw grid of numbers.
| What the assessment needs | Spreadsheet or desktop tool | Lumex |
|---|---|---|
| The current 2024 third edition | Drifts out of step with the standard | The 2024 edition is built in |
| The working behind every number | Assumptions buried in cell formulas | A full coefficient trace, there to check |
| A record of who changed what | No revision history or audit trail | Every change recorded, end to end |
| The whole team on the same projects | One machine, one person's licence | Shared projects with role-based access |
| A deliverable you can file | A raw grid of numbers | A branded, auditor-ready report |
| Nothing to install | Tied to one desktop | In the browser, on any machine |
Who runs IEC 62305 assessments in Lumex
The software is built around how an IEC 62305 assessment actually gets done, in-house or for clients.
Electrical consultants
