Lightweight aggregate concrete block is listed as conductivity 0.20, density 600 and specific heat 1000. No row states conductivity 0.19 with the stored radiative pair 0.37/0.92.

Assessment findings

Namesupported
The historical catalogue row supplies the Concrete Block (Lightweight) configuration label.
Targetsupported
The row stores optical and thermal material properties.
Valuessupported
The exact tuple is supported as a retained historical configuration row, not as a verbatim CIBSE lightweight-block condition; Guide A's nearest named row uses conductivity 0.20, not 0.19.
Sourcesupported
Unreferenced is correct because no CIBSE row states the complete tuple. source_legacy_ref 90240071 retains the migrated registry link without exporting it as the parameter publication.
issue #261
Placenot applicable
The generic material row makes no observation-place claim.
Representativenessnot applicable
The record makes no site, city, or regional evidence-reach claim.
Methodsupported
Assumed records retention without claiming that 0.19 is a deliberate rounding or transformation.
Identitysupported
Legacy ID 36248162 identifies the distinct retained material-registry row; no narrower physical block condition is inferred.

Scientific note

The tuple is retained exactly as a historical configuration artifact. Similarity to the 0.20 CIBSE row does not authorize rounding or replacement. Source unreferenced, method assumed, and source_legacy_ref 90240071 make the distinction explicit without changing any value or choosing a new material identity.
