This is what a buyer checks before they shortlist electrical and electronics suppliers.
What does a buyer check before ordering cable?
They check the conductor size and material, the insulation and sheath, and the voltage rating against a named standard. Then fire performance, which has become the governing requirement in building work and is where cheaper cable usually differs.
An electrical contractor is buying cable that will be inspected and must satisfy a building's fire specification.

First, what the product is
The fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Conductor material and cross-section
Copper and aluminium at a stated size.
- 2
Number of cores and configuration
Determines the application.
- 3
Insulation and sheath material
Governs temperature rating and fire behaviour.
- 4
Voltage rating
The specification the installation is designed to.
- 5
Standard the cable is manufactured to
Determines acceptance and testing.
- 6
Fire performance classification
Now the governing requirement in most building work.
- 7
Current carrying capacity
The figure the installation design uses.
Then the paperwork
Naming the documents you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Type test certificateAsked at: specification and approval | Conformity with the cable standard the product claims | Publish it |
| Routine test certificateAsked at: every delivery | Electrical tests performed on the delivered drum | Per shipment |
| Fire performance test reportAsked at: building projects — often decisive | Reaction to fire or circuit integrity under a named standard | Publish it |
| Conductor resistance test reportAsked at: acceptance | That the conductor meets the specified resistance | Per shipment |
| Third-party certificationAsked at: regulated markets | Independent product certification where the market requires it | Publish it |
| Substance compliance declarationAsked at: procurement | Compliance for the destination market | Publish it |
| Drum length and marking specificationAsked at: ordering | Standard lengths, marking and packing | Publish it |
The shortlist moment
A buyer lines up a few suppliers and keeps the ones whose proof is easy to check. The rest get a closed tab, not an email.
The buyer asks: What does a buyer check before ordering cable?
A few suppliers get compared side by side:
A supplier with Type test certificate on the page
Conformity with the cable standard the product claims
A supplier with Fire performance test report on the page
Reaction to fire or circuit integrity under a named standard
A supplier with Third-party certification on the page
Independent product certification where the market requires it

Questions suppliers ask
Why has fire classification become the first question?
Because building fire specifications now name cable classifications explicitly, and installations are inspected against them. A cable that cannot be matched to a classification cannot be installed in those buildings, which makes it the first filter rather than a technical footnote.
Should current carrying capacity tables be published?
Yes. They are what an installation designer uses, and having them available makes your cable easy to design in. Manufacturers who publish them get specified at the design stage rather than quoted at the purchasing stage, which is a much better position.
How do we compete against substandard cable on price?
By making the differences checkable: conductor resistance, insulation thickness, the test standard and third-party certification. Undersized conductors are the most common form of substandard cable, and a supplier who explains how to verify it wins the buyers who have been caught.
Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list.
