Methodology
Where these numbers come from.
Short version: standards and warranty documents over brochures, and we tell you when the answer depends on your jurisdiction instead of pretending a web page settles it.
What we lean on
Three kinds of question, three kinds of source.
Where a claim only exists in supplier material, we say so on the page rather than dressing it up as something checked.
Safety and code
The standards themselves — NFPA 855, UL 9540 and UL 9540A — plus the adopted building and fire codes in the jurisdiction being discussed. Where a certification is claimed, the certifying body's own listing database rather than a logo on a datasheet.
Performance and degradation
The warranty document, because it is the only performance statement a supplier is contractually bound to. Marketing figures and warranty figures often disagree. We quote the warranty.
End of life
Processor permits and registrations, transport classification under the applicable dangerous goods rules, and downstream documentation. A recycling claim with no named downstream is not a claim.
Two things worth knowing
Code moves, and so do we.
Code adoption and product certification both change, and a page that was right eighteen months ago can be wrong today. Anything time-sensitive carries the date it was checked. Where a jurisdiction or a certification is the deciding factor, confirm it locally.
We will get things wrong. When we do we correct the page and say what changed. If you can point at a primary source that contradicts something here, that is the fastest way to change it — including if you are the supplier being discussed. Published by Xenco Labs Inc..
