Specifications travel with a product. States do not.

A specification is a property the manufacturer established

A capacity, a material, a neck finish, a wall thickness, a case pack. It is true of every unit produced to that specification and it can be published once.

A state is a property of one particular object right now

Whether this drum is rusted. Whether this container leaks. It is true of one unit at one moment and it cannot be published at all.

Which is why a catalog can answer the first and never the second

Everything recorded on this shelf is a specification. Nothing on it is a state, and no page here infers one, including about containers that have been sitting in a warehouse.

The distinction explains a gap this library has reported five times

Five properties now independently report that no container record carries a lot number, a batch, a production date or a certification reference. Those are all identity rather than specification.

And identity is what connects a specification to a state

Without it there is no way to say which production run a particular jar came from, which is the first step in saying anything about its condition.

For a shelf of small dry storage jars that gap costs nothing

Nobody is asking a bits jar to carry a chain of custody. The point is that the shelf cannot support a claim that depends on one, so the pages do not make such claims.

The spine is the clearest illustration available of why it matters

Paragraph (b) asks a question about a container that only an inspection of that container answers. No amount of catalog data substitutes for somebody looking.

Which also means the rule needs no certification machinery

Compare the composite wood standard, where compliance is invisible and the answer is five tests, a regression, an inspection and a third-party certifier. Here the answer is to look at the drum.

Two rules, two kinds of property, two completely different structures

An invisible continuous emission rate produces a documentary regime. A visible physical condition produces a two line requirement. The shape of the rule follows the shape of the fact.

And that is the useful general lesson from this property

Before asking what a record should contain, it is worth asking what kind of property is being recorded. A specification can be stored. A state has to be checked.

40 CFR 279.22(a) and (b). Paragraph (a): "Used oil generators shall not store used oil in units other than tanks, containers, or units subject to regulation under parts 264 or 265 of this chapter." Paragraph (b): "Condition of units. Containers and aboveground tanks used to store used oil at generator facilities must be: (1) In good condition (no severe rusting, apparent structural defects or deterioration); and (2) Not leaking (no visible leaks)." The section also notes that used oil generators are subject to Spill Prevention, Control and Countermeasures under 40 CFR part 112, and to the Underground Storage Tank standards of 40 CFR part 280 for used oil stored in underground tanks "whether or not the used oil exhibits any characteristics of hazardous waste". law.cornell.edu

The Davis Pack Supply catalog, measured 19 October 2026. Ten specification labels appear across this group’s 238 containers, with the number of rows carrying each and the number of distinct values it takes: Capacity, 238 rows and 29 values; Color, 238 and 9; Material, 238 and 3; Temperature range, 238 and 3; Case pack, 237 and 82; Height, 224 and 146; Neck finish, 222 and 21; Recyclable, 117 rows and one single value; Width, 14 rows and 11 values; Liner, one row and one value. On this shelf the three temperature range values map one to one onto the three materials: 117 PET rows read minus 40 to 120 F, 71 polypropylene rows read 0 to 240 F and 50 glass rows read minus 100 to 300 F. Across the whole catalog of 2,150 products the field takes nine distinct values, so it is not a material restatement everywhere, only here.

Written from 40 CFR 279.22 and from the catalog as it stood on 19 October 2026. That section governs how a used oil generator stores used oil; it does not govern fuses, clips, clamps, bulbs, retainers, caps or valve stems, and it does not reach any container on this shelf. Nothing here says any container may be used to store used oil or any other fluid, and nothing here is guidance about handling or disposing of used oil. No container on this shelf is described as being in any particular condition, because the catalog records a specification and not a state. This shelf is a subset of the store-small-dry shelf and the sewing notions property enumerates that shelf.
