Editorial standards

Every published claim.
Primary-source evidence.

Gulfstone does not publish a capability or compliance claim on the strength of a competitor’s brochure, an unverified listing or a supplier’s self-declaration. Every such claim is traced to documentation we control or can obtain directly — and signed off by the person who would have to stand behind it.

Last updated

The evidence hierarchy

Three tiers of source.
One of them can carry a claim.

Every source is classified before it is allowed to support anything. If a claim cannot reach the primary tier, it is qualified with an explicit disclosure or removed — never quietly softened.

Tier 1

Primary sources

Can carry a published claim on their own.

  • Output from our own test lab — flue-gas analysis, gas-boiler furnace performance, spray and moisture testing, and a mute room.
  • The certificate and test report issued for the specific configuration approved, for example an AGA, CSA or CE document.
  • The controlled drawing, BOM and tolerance stack that the production line actually builds to.
  • Plant production and QC records — line capacity, detection-platform output, and the in-line check records behind a QC claim.
  • Executed OEM / ODM and tooling agreements, and container loading manifests with customs documentation.
Tier 2

Supporting sources

Context only — never the proof.

  • Regulator and standards publications that position a requirement, such as the standard a certification is tested against.
  • Trade press and industry reports that cite primary data — we follow the citation back rather than quoting the article.
  • A supplier datasheet, once it is filed alongside the certificate or test report it belongs to.
  • Third-party inspection reports, when they are attached to a specific lot rather than quoted in general.
Tier 3

Unacceptable sources

Prohibited as the basis of any claim.

  • A competitor’s brochure, marketplace listing or pay-to-play directory entry.
  • A supplier self-declaration with no documentation behind it.
  • Uncertified test results, including our own drafts before the accountable engineer has signed them.
  • An AI-generated summary, or any restatement of a source we have not read ourselves.

Where evidence comes from

Four categories of
primary-source verification.

A claim is verified against at least one of these four, and we name the issuing body rather than summarising it.

01

Certifications & compliance

Certification documents and test reports for the specific configuration approved — AGA for Australia and New Zealand, CSA for North America, CE for Europe and the UK — held by the person who owns the file.

02

Engineering & manufacturing

Controlled drawings, bills of material, tolerance stacks and DFM records. A claim about what the line builds is checked against the document the line builds to.

03

Test & performance

In-house lab output: Siemens flue-gas analysis, the gas-boiler furnace performance rig, spray and moisture testing, and the mute room. Capacity figures come from the production records behind them.

04

Trade & logistics

Container loading manifests, packing lists, customs documentation and mixed-container cube plans — the paperwork that shows what actually left the plant on which date.

The process

Five verification gates.
No exceptions. No shortcuts.

Every technical claim moves through the same five gates before it is published, in the same order, whoever wrote it.

Gate 01

Source identification & classification

The claim is stated as narrowly as the evidence allows and tagged to a tier before drafting begins. No rounding up, no “industry-leading”.

Gate 02

Document verification & cross-check

The source is matched to the claim: which report, which certificate, which drawing, which record. A certification is checked against the approved configuration, not the product range in general.

Gate 03

Engineering & compliance review

The engineer who set the tolerance, or the person who holds the certificate file, reads the claim as written and confirms the evidence supports it. This is a sign-off, not a courtesy read.

Gate 04

Language & disclosure review

Where the evidence is directional rather than measured, the claim says so. Where a figure is a typical value, it is labelled typical. Nothing vague is allowed to stand in for something unproven.

Gate 05

Post-publication monitoring & re-verification

When a product, a certificate or a figure changes, every claim that depends on it is revisited and updated or withdrawn — it does not stay up on the strength of having once been true.

Who checks

Not generalist editors.
The engineers who set the spec.

Claims are checked by the people accountable for them, not by a copy team working from summaries. An editor can check that a sentence is well-formed; only the person who set the tolerance can check that it is true.

Direct access to the engineers

A question about a specification goes to the engineer who wrote it, in English, rather than through a sales desk. The answer usually arrives inside a day.

Production floor validation

A claim about the line — capacity, output per shift, what the detection platforms test — is checked against the line, not against a previous marketing page.

The file-holder signs, not a summariser

Certification claims are signed off by whoever holds the certificate and test report, so the name behind the claim is the name on the document.

Re-verification

Verification does not end
at publication.

Content of ours that states a fact carries a re-check date. These are the four kinds that do, and what triggers a revisit.

Product specifications

BTU range, dimensions, cut-outs and packaging data are re-checked whenever a revision lands, so a spec page cannot outlive the drawing it was written from.

Certification & compliance pages

Re-verified against the certificate on file. When a certification lapses or a standard is revised, the dependent claims are updated in the same pass.

Plant & network facts

Floor area, platform count, shift output and partner-factory count are taken from current records, not carried forward from an earlier page.

Technical guides & explainers

Where a guide leans on a standard or a regulator’s requirement, the citation is re-read against the current published text.

The difference

Industry claims.
Verified facts.

The same sentence can be either, depending on what is behind it. This is the distinction we hold ourselves to.

A claim without a source

  • States a capability with no document that can be produced on request.
  • Describes a product range, when only one configuration was ever tested.
  • Rounds up — “up to” language with no ceiling stated.
  • Rests on a certificate that lapsed, or on a standard never actually tested against.

A verified fact

  • Can be answered with “show me” — a report, certificate, drawing or record.
  • Names the specific configuration and the standard it was tested to.
  • States the figure as measured, and labels a typical value as typical.
  • Carries the date it was last checked against the source.

Corrections

When new evidence
changes what we know.

Evidence moves. A certification is superseded, a standard is revised, a component is replaced on the line, a figure turns out to have been read from the wrong revision. When that happens the claim is corrected at the source — not reworded to survive.

We do not quietly remove a page that has been quoted. If a claim was published and is later shown to be wrong, the correction is noted on the page that carried it, so anyone who cited it can see what changed.

If you find an error, tell us the page and the specific point. A well-aimed correction is useful to us, and we say so rather than arguing the point.

Worked example

A certification claim outlives its certificate

  1. A product page states that a model carries an AGA approval for Australia and New Zealand.
  2. Gate 05 flags the certificate as approaching renewal, and the page is added to the re-check list.
  3. The certificate is renewed against the same configuration: the date behind the claim is updated and nothing else changes.
  4. Had the configuration changed — a different burner, a different gas path — the claim would have come down until the new configuration was tested, and the page would say why.

Questions

About fact-checking

Who actually checks a claim at Gulfstone?

The person accountable for it. A tolerance is checked by the engineer who set it, a certification by whoever holds the certificate file, a capacity figure against the production record. The sign-off is not delegated to a copy team, because a copy team cannot verify a specification.

How often is published content re-verified?

Content that states a fact carries a re-check date. Anything tied to a product revision or a certification is revisited when that revision or certificate changes, and the plant and network figures are taken from current records rather than carried forward.

What happens if an error is found after publication?

It is corrected at the source rather than reworded. Where the claim was published, the correction is noted on the page that carried it, so anyone who quoted it can see what changed. Report a suspected error to Olivia.huang@gulfstonegroup.com with the page and the point.

Will you accept third-party inspection or audit?

Yes. A third-party audit of the plant is already on file, and inspection by SGS, TÜV or your own agent is welcome. Certificates, test reports and declarations ship inside the container with an order.

What do you do with a claim you cannot evidence?

It is qualified with an explicit disclosure, softened to what the evidence supports, or removed. A claim we cannot trace does not go on the page as written — the test is whether we could answer “show me” if a buyer asked.
