Application intelligence / Collection 1.0
Government & municipal
NSF/ANSI 60, “or equal,” 23 percent, a qualified product: a public buyer writes chemistry into a solicitation that bidders, auditors and a reviewing authority will hold them to. Each of those words names a rule, a listing, a basis or a named product. None of them is enforceable until the document says which.
From application to a better specification
Writing a chemical bid specification a public buyer can enforce
A bid is judged against the words of the solicitation. Name the rule and its edition, the certification of the offered product, the characteristics an equal must meet and the delivery documents, or none of them can be held to.

The ammonia side of chloramination is a purchase with three possible forms, at least two percentage bases and a vapour pressure. None of that sets a ratio, and this guide supplies none.

Flake, liquor and a qualified manufactured product are three different things called calcium chloride. A winter-maintenance specification decides which one it means, and writes the delivery into the bid.

Build a requirements brief
Keep requirements, evidence and open questions together. Entries stay in this page’s memory until you leave or reload; this worksheet does not submit them. Download a text copy for your own review. Do not enter confidential or controlled technical information.
Connect the requirement to the material
Once your team has defined the application requirements, review the exact product’s available documents. Ask about packaging, lot evidence and unresolved sourcing questions; an industry listing is not an application approval.
