Standard
YB/T 6493-2026 is the Chinese industry standard for graphene flexible electric heating film. It was published on 2026-04-16 and takes effect on 2026-11-01. XGRAPHENE (operated by XIHE) is one of the drafting units. Drafting participation is not a product certificate.

The standard sets out how graphene flexible heating film is described, measured and compared. It covers the areas below. Public summaries are what we can restate here; the full text is published by the standard body.
Clause 3.8 defines electric-to-thermal-radiation conversion efficiency — the share of electrical input that leaves the surface as thermal radiation. This is the quantity our 68% figure is reported against.
XGRAPHENE (operated by XIHE) is one of the drafting units of YB/T 6493-2026. The first-named drafter is Fu Wenxing. Taking part in drafting means contributing engineering input to how the category is defined and measured. It does not mean we set the standard alone, and it does not make our products automatically better than anyone else's.
No product on this site holds a certificate to YB/T 6493-2026, and we do not claim that any product meets it. If you need evidence for a specific part, ask for the test report and the conditions it was measured under.
Five questions worth asking any supplier who mentions a standard:
Our film-level figures come from report (2022)WT-HW-00529, issued by the National Infrared & Industrial Electrothermal Products Quality Inspection & Testing Center (Wuhan), using methods JG/T 286-2010 and GB/T 7287-2008.
| Figure | Value | Basis |
|---|---|---|
| Normal total emissivity | ≥ 0.88 | Film sample, report (2022)WT-HW-00529 |
| Electric-to-radiant conversion efficiency | 68% (double-sided) | Film sample, report (2022)WT-HW-00529 |
Two points of honesty about that report. It dates from 2022, before the standard existed, so it was not produced under YB/T 6493-2026. And it was measured on a film sample, not on a panel, module or finished product. Both facts are part of the claim, not a footnote to it.
It is the Chinese industry standard for graphene flexible electric heating film. It was published on 2026-04-16 and takes effect on 2026-11-01. It sets out shared definitions and test logic for the category.
No. A standard creates a comparison framework. It does not make two films equivalent, and it does not replace product-level testing or integration review.
It means XGRAPHENE (operated by XIHE) took part in writing the definitions and test logic. It is not a product certificate, and it does not mean any product is approved to the standard.
No. Report (2022)WT-HW-00529 predates the standard and was produced using JG/T 286-2010 and GB/T 7287-2008. We state the method with every figure so the basis is clear.
Tell us the application and we will send the film data with its report number, method and sample basis.
