CPR traceability for electrical cable — a meter without a class does not go on site.
The Construction Products Regulation requires you to justify the reaction-to-fire class of every meter of cable that arrives on site. iLEAN Tracer ties batch, DoP and Eca/Dca/Cca class to the extruder head, to the drum and to the site delivery note — traceability builds itself on the line. The person signs.
Every meter of cable carries a class — and almost never carries the data with it.
The CPR requires every cable permanently installed in a building to carry CE marking, a DoP and a justified reaction-to-fire class. In most cable plants that trace lives in separate places:
- The DoP and the class — product-type documentation, signed by the technical manager, sitting in a network folder.
- The batch and the drum — the physical drum label, the MES record, the weight and length taken at winding.
- The delivery to site — the sales rep's delivery note, sometimes with the drum cut to length in the warehouse, which breaks the original link.
When the installer needs to justify the 30 meters they ran up a stairwell riser, someone spends an afternoon rebuilding the trace from inferred data. It works 99% of the time. That 1% is a site shut down or an enforcement file — and neither the manufacturer's nor the installer's liability fades with time.
iLEAN does not add a fourth system — it seals the cracks between the three you already have.
The problem with CPR traceability is not a lack of information: it is information living in islands that is not stitched together on the day the installer asks. iLEAN acts as the putty that fills those gaps, without asking you to change your ERP, your MES or your extrusion line.
The extruder marks by the meter. Connect captures the winding and the delivery note. iLEAN Tracer (the traceability agent) stitches batch, DoP and class to the physical meter. The person signs — never the other way round.
The iLEAN pieces applied to CPR cable traceability:
- Edge — vision over the extruder head and the per-meter inkjet marker. It reads the printed part number, validates that the marking is legible and that the formulation coming out matches the production order. If it does not, it holds the winding before the drum is closed. Works with no network.
- Connect — captures the weight and the length wound onto each drum (whether from a modern scale or from an old PLC), the incoming polymer batch (a photo of the supplier's delivery note taken in the app), and the delivery to site from the logistics ERP. Whatever arrives by email, WhatsApp or a phone call from the sales rep enters at second zero.
- iLEAN Tracer (the traceability agent) — keeps the meter-batch-DoP-class record live. When the warehouse cuts a drum to length, the cut inherits the batch automatically. When the installer asks about the 30 meters in a stairwell riser, the dossier comes out in one click, signed by a person.
Rebuilt trace vs. live CPR traceability with iLEAN
| Aspect | Classic CPR traceability | With iLEAN Tracer |
|---|---|---|
| Link between meter produced ↔ batch | Drum label + MES spreadsheet | Head and inkjet readings, live automatic record |
| Drum cut in the warehouse | Loses the link to the original batch | Inherits the batch and the DoP when cut |
| DoP and reaction-to-fire class | PDF in a network folder, far from the physical meter | Tied to the batch, the drum and the site delivery note |
| Delivery to site | Sales rep's delivery note, no technical link | Delivery note linked to batch and class |
| Installer's query | Rebuilt from inferred data, too late | One-click dossier, in seconds |
| Market surveillance inspection | Risk of failing to prove the declared class | Every meter backs its class with signed evidence |
Impact estimate for your plant — to be validated with your numbers.
The block below is an estimate to be validated with the specific data of your plant. We put it forward so the committee has an order of magnitude; we refine it during the diagnostic.
- Mid-sized manufacturer of CPR low-voltage cable, one extrusion + winding line, multiple classes (Eca, Dca, Cca) and part numbers.
- Tracer pilot on one line (head reading + inkjet + winding scale + integration with ERP and MES). First value expected within a few weeks: the first drum whose trace is closed the moment winding ends.
- Indicative payback between 4 and 9 months, depending on how often traces are rebuilt by hand today and the average cost of a site held up.
- Expected reduction in time spent rebuilding traces of ≥ 30%, a defensible floor. The hard lever is a single site held up by an incomplete trace: that alone pays for the pilot.
And the quality manager's reasonable doubt
“What if the AI confuses an Eca class with a Dca?” — hallucination is a problem of free generation, not of anchored tasks. In tasks where the AI merely recontextualizes a piece of data from one system into another (reading the head and cross-referencing it with the DoP and the production order), the best models brought error below 1.5% [1]. And even so, what is critical is never decided alone: iLEAN holds the drum and the person signs. The three safety rings exist precisely for this.

What people ask about CPR cable traceability with AI
What does the CPR require of electrical cable arriving on site?
The Construction Products Regulation (EU) 305/2011 (CPR) requires every electrical cable permanently installed in a building to carry CE marking, a declaration of performance (DoP) and a reaction-to-fire class (Aca, B1ca, B2ca, Cca, Dca, Eca, Fca) verified to EN 50575 and EN 13501-6. On site you have to be able to prove which class went into which meter, by batch and by DoP. The trace is not optional — it is the basis of both the installer's and the manufacturer's liability.
How do you tie batch, DoP and class to every meter produced?
Today, in most cable plants, class and DoP live in the product-type documentation, the batch lives in the MES or on a drum label, and the delivery to site lives in the sales rep's delivery note. If the warehouse cuts a drum to length, the link is lost. iLEAN Tracer stitches it together on the line: the agent reads the extruder head (part number, formulation, polymer batch), the per-meter inkjet marking, and the weight and length wound onto each drum, and keeps a live record tying every meter produced to its DoP and its class. When the sales rep cuts the drum, the cut automatically inherits the batch and the trace.
What if an installer asks for the trace of the 30 meters they ran up a stairwell riser?
It is the classic nightmare: the end customer asks, the sales rep calls the plant manager, someone searches three systems, and either the trace is rebuilt from an inferred data point or the risk is simply accepted. With iLEAN Tracer the question is answered in seconds: the delivery note shipped to that site (captured by Connect from the logistics ERP) is linked to the drum, the drum to the extruder batch, the batch to the polymer batch, and all of it to the signed DoP and the declared Cca/Dca/Eca class. The dossier comes out in one click, with a human signature at the critical moment.
Does it work if part of the cable was made a while ago and part of it now?
Yes. CPR traceability does not require continuous production; it requires the trace to be tied to the physical product. iLEAN Tracer does not need to rewrite history to start delivering value: it starts tracing what you produce from day zero of the pilot, and connects to the DoP and batch data that already exists for the drums in the warehouse. So it does not force you to throw away anything you already have — it is the putty that fills, not the wall you demolish.
How much does a Tracer pilot cost in a CPR cable plant?
The order of magnitude of a Tracer pilot on an extrusion + winding line for CPR cable is close to that of any iLEAN pilot in a plant: an initial investment in capture (extruder head, inkjet, winding scale), integration with your ERP and MES, and training for the quality and sales teams; plus an annual license. A reasonable payback to put in front of the committee is a matter of months — the hard lever is a single site held up by an incomplete trace (days of downtime, a penalty, brand damage with the developer): that alone pays for the pilot.
