Eight categories are refused, each with a reason; the two most expensive refusals are product reviews and affiliate links, and both are kept deliberately.
Not detailed: what this set will not draw
rev Aissue 04rev Adrawn by The Transom Set (a named set, not a person)
The list, with a reason per line
| Not drawn | Reason |
|---|---|
| Product reviews and rankings | a review needs comparative testing this set does not run, and without it the sheet is an opinion with a link in it |
| Affiliate or sponsored content | the set has no revenue relationship with any manufacturer, and introducing one would change which sheets exist |
| Project galleries | judged by photograph rather than by measurement, which is the opposite of what this set does |
| Warranty, liability and claims advice | no responsible party here can answer a question about somebody's exposure |
| Price, lead time and supply chain | not properties of an assembly, and they change weekly |
| Whole-building energy modelling | a different calculation with a different owner and different inputs |
| Specification writing for a project | the set describes what an assembly measures; it does not write anybody's specification |
| Anything without an extra inch | a sheet that repeats the first page of results has no reason to exist |
The two refusals that cost the most
Refusing product reviews removes the highest-traffic content in this subject area, and refusing affiliate links removes the obvious way to pay for the set. Both refusals are kept because the alternative is a set whose sheets exist to move a purchase rather than to answer a measurement question, and readers can tell the difference, which is exactly why the measurement sheets would stop being believed.
What happens when a topic is borderline
If a topic needs a test this set cannot run, it is refused. If it needs a test this set can run but has not run, it is deferred and listed as an open question. If it needs a test this set has run on one assembly, it is published as a revision with the specimen, the condition and the result stated, and it is marked as a figure that can move.
A refusal list is also a scope guard. Without one, a set drifts toward whatever gets traffic, and the drift is invisible until the site is a different site.
Documents this sheet is drawn from
- 1The Facts about the Component Modeling Approach (CMA) - NFRC Informational Packsupports the certification route that a product comparison would have to match
- 2FGIA Technical Resources (standards and codes related to building design)supports the industry technical resources the set's scope is bounded by
- 3NFRC Technical Documents (technical standards index)supports the technical document index that defines what a test method has to state
Each line points at one specific document, with its own title as the link text. No line is a home page and no line is a search result.
