Concentrate is not the listed object. OSFM 8140-2395:0001 applies to the complete named assembly, and ESR-5231 is the second of 2 listings (ESR-5231). SFM 12 7A 1 is the test standard on attributes.
Warnings say to match the weather-resistive barrier, lath, base and finish coats, substrates, fasteners, thicknesses, and mixing. Uniwall concentrate by itself is not that assembly.
Lot comparison is how the complete named assembly meets a place. SFM 12 7A 1 on the concentrate bag would still leave the lath, coats, and substrates unmatched.

Specification notes
The OSFM listing applies to the complete named assembly, not Uniwall concentrate by itself. Match the weather-resistive barrier, lath, base and finish coats, substrates, fasteners, thicknesses, mixing, curing, and installer conditions to the current listing and ESR-5231.
ESR-5231 evaluates structural, durability, weather-protection, construction-type, and specified fire-resistance uses. It does not replace the separate OSFM WUI listing or expand that listing.
