thermal_conductivity | 0.035 |
specific_heat | 1400 |
density | 40 |
Where: Table 3.46, extruded polystyrene row, p. 3-49
Publishes extruded polystyrene as density 40 kg m-3, thermal conductivity 0.035 W m-1 K-1 and specific heat 1400 J kg-1 K-1.
Where: Pre-migration Spartacus Material row 36248194
Stores the same thermal tuple under MAPSECC Ref 90240069; the root spreadsheet contains the same row, excluding YAML migration as the cause of the attribution.
| Name | supported Guide A names the material extruded polystyrene, exactly matching the retained identity. |
|---|---|
| Target | supported The source table and historical catalogue both describe thermophysical material properties. |
| Values | supported Table 3.46 publishes density 40 kg m-3, conductivity 0.035 W m-1 K-1 and specific heat 1400 J kg-1 K-1 for extruded polystyrene, exactly matching the stored tuple. |
| Source | supported CIBSE Guide A is the direct parameter source. The historical catalogue attributed this row to the MAPSECC dataset, but the MAPSECC author clarified that material values should cite CIBSE and that Hertwig et al. should be cited for the UK typologies instead. issue #833 |
| Place | not applicable The generic material row makes no observation-place claim. |
| Representativeness | not applicable The generic material row makes no site, city or regional evidence-reach claim. |
| Method | supported Literature denotes direct adoption of all three thermophysical values from Guide A. |
| Identity | supported Legacy ID 36248194 identifies the retained catalogue row; correcting its source does not change the stable record path, its values or its material identity. |
This correction changes provenance only: the complete stored tuple is an exact CIBSE Table 3.46 row. A repository-wide usage search finds this material unlinked from any current construction record. The stable record path remains unchanged because paths are database identities, not current citation labels.
