ISSUE 04 · REV C The Transom Set

This set is drawn with machine assistance and verified by script and by document; it names no human author because there is none, and it invents no credentials.

What this set is

A working set of drawings about window and facade assemblies: what the standards print, what a test returns, and where the two disagree. It is drawn with machine assistance and checked against the documents it cites. It is not a laboratory, a testing house, or a person with a reputation to protect. The responsible party is the set, and that is what every sheet says.

No sheet claims a laboratory, a site visit, or a named author. There is no byline because there is no person to name, and inventing one would be the single worst thing this set could do.

The four tests every sheet has to pass

  1. Swap test: replace the set's nouns with another domain's nouns. If the sentences still work, the sheet is generic and gets rewritten.
  2. Strip test: remove every adjective and adverb. Nouns, dimensions, standard numbers and test results must remain.
  3. Take-away test: hand the edge table, the pressure ladder or the worked example to someone who works on windows. It must be usable with no surrounding prose.
  4. Refute test: the sheet must contain at least one sentence a practitioner could disagree with. A sheet of correct generalities fails.

How mark-ups are handled

A mark-up is a change to a figure, a unit or a claim, plus a line saying what changed and on what basis. The sheet's revision letter moves and its issue date moves; its address does not. Rewording a definition to look fresher is not a mark-up and is not done here.

Documents this sheet is drawn from

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.
