Worth knowing about this source

This chapter sets its equations, chemical reactions and some table symbols in a symbol font, so they come through as characters nobody can type and no search will match. Read an equation in the handbook itself before relying on it; the prose around it is ordinary text.

Why the wording is not on this page

This is a US government work, free to quote and cite. The corpus reads it page by page from the official copy, and a citation names a page of it, so this page says what the document is, which edition it is, and links that copy.

How a question cites it

A citation to this document carries the page number of the file this site read, an exact quote, and the anchor of the page it is on, which counts the pages of the file and not the numbers printed on them. You can check every claim against the copy linked above.
