Check the delivery against your written quotation before you sign for it: the description, size, cores, sheath print, supplied length, packaging and paperwork.
Most delivery problems are mismatches, not bad copper: the wrong core count, a 45 m coil where 90 m was quoted, a strand code where a mm² size was agreed. Those you can catch at the gate in ten minutes. What you cannot catch by eye is conductor quality; that needs a resistance measurement or a test report, and the checklist below says which is which.
You can only check a delivery against something written down. Keep the final quotation or order open on your phone, with one line per cable showing the items below. If a line is missing, ask the supplier to confirm it in writing before dispatch, not after the cable is on site.
| Item on the quotation | Example of a complete entry | Why it matters at delivery |
|---|---|---|
| Cable type and conductor | Copper, flexible (class 5) or stranded (class 2) | Flexible and standard cable look alike on a coil |
| Nominal size | 2.5 mm², or 7/.029 with the nominal mm² stated | A strand code alone does not fix the nominal size |
| Number of cores | 3 core | The most common delivery mismatch |
| Insulation and sheath | PVC/PVC, voltage rating 450/750 V | Should match the sheath print |
| Supplied length per package | 90 m per coil, 4 coils | A coil is packaging, not a fixed length |
| Quantity and unit | 360 m total | Lets you total what was delivered |
| Delivery address and date | Site address in Lahore, agreed day | Who receives and signs |
If you have not ordered yet, the quotation checklist lists what to ask for, and price per metre, foot or coil shows how to put two quotations on the same unit.
Work through these with the delivery still on the vehicle or just unloaded. Note anything that does not match on the delivery note before signing.
| Check | How | What a mismatch looks like |
|---|---|---|
| 1. Count the packages | Count coils or drums against the order lines | Fewer coils, or two lines delivered as one |
| 2. Read the label or tag | Compare product description, size and cores with the quotation | A label for 2 core on a 3 core order |
| 3. Read the sheath print | Unroll a metre and read what is printed along the cable | Print that disagrees with the label, or no print at all |
| 4. Count the cores | Look at the cut end: count insulated cores and note the colours | Wrong core count, or no earth core where one was ordered |
| 5. Check the conductor build | Flexible has many fine strands; standard has a few thicker ones | Solid or coarse strands where flexible was ordered |
| 6. Look for damage | Crushed or cut sheath, kinks, flattened coils, wet packaging | Any cut through the sheath, or water inside the packaging |
| 7. Check the paperwork | Delivery note or invoice lists the same lines and quantities | Paperwork describes a different size or length |
| 8. Note the length to verify | Record which coils you will measure (see below) | — |
A coil is packaging, not a standard length, so check the length your quotation states rather than assuming one. There are two practical ways:
Unroll one coil on a clean floor in measured lengths (a marked 5 m or 10 m run works) and count. If one coil is short, ask before checking the rest.
Some cables are printed with running metre marks. Subtract the reading at the inner end from the reading at the outer end. Not every cable carries these marks.
Convert carefully if the quotation is in feet or yards: 1 ft = 0.3048 m and 1 yd = 0.9144 m exactly, so 300 ft is 91.44 m and 100 yd is 91.44 m. Compare length with length, never a coil count with a metre count.
Matching a delivery to the order is worth doing, but none of the gate checks proves what the conductor is made of or that the cable meets a standard.
| Check | What it can show | What it cannot show |
|---|---|---|
| Colour and shine of the copper | That the conductor looks like copper | Purity; copper-clad or alloy conductors can look similar on a fresh cut |
| Strand count | The conductor build (flexible or stranded) | The cross-section is large enough; thinner strands give the same count |
| Weighing the coil | A gross difference from the weight your supplier states | Conductor area on its own: insulation, sheath and packaging are in the weight too |
| Sheath print | What the maker declares | That the declaration has been independently tested |
| QR code on the box | That the code leads to the maker's own record for a batch | The length of this coil, the conductor quality, or that a code was not copied onto other packaging |
Pilone boxes carry a QR code that opens a product record showing the cable size, batch number, manufacturing year and conductor. Compare what the record shows with the box and the sheath print. It helps you spot packaging that does not belong to the batch it claims; it is not a test of the cable inside.
The meaningful check on a conductor is its resistance. IEC 60228 sets a maximum resistance per kilometre at 20 °C for each nominal size and conductor class, and a conductor that measures above it is not that nominal size, whatever the label says. For example, the limit for a 2.5 mm² class 2 conductor is 7.41 Ω/km, so one core of a 90 m coil may measure no more than about 0.67 Ω at 20 °C.
Values that small are near the floor of an ordinary multimeter, whose own leads and contacts add a similar amount, and copper reads higher when it is warm. A reading worth acting on needs a low-resistance (four-wire) measurement and a temperature correction. The full table of limits, a worked example and what Pilone can and cannot measure are on cable testing: what can and cannot be checked. Whether the metal is copper at all is a separate check, described on how to check the conductor yourself.
