Standard
EN 15804+A2 — EPD modules and declared impacts
Clause 6.3. Requires modules A1–A3 (product), A4–A5 (construction), B1–B7 (use), C1–C4 (end of life) and module D (benefits beyond the system boundary). Comparing timber products is only valid when the declared unit, service life and module set are identical; a cradle-to-gate A1–A3 number alone cannot be compared with a cradle-to-grave figure.
The diagram below shows every direct connection this node has in the graph. Each line is one edge; expand a neighbour group below to read exactly why that connection exists and which standard or dataset it comes from.

How edges in this graph are derivedWI-GRAPH v1.0.0
Species → agent edges come from the WI-SL resistance profile (0–100 ordinal scale derived from EN 350 durability class, extractive chemistry and movement). ≥70 is read as "resists well", 45–69 as "moderately resists", below 45 as "is vulnerable to".
Climate → agent edges fire when a climate's driver value (UV, humidity, salt or freeze-thaw load) is 60 or above, read directly from the climate dataset.
Treatment → agent / standard edges come from the paraphrased standards corpus used across the site (EN 927-1, EN 351-1, EN 350 clause 4, EN 13501-1).
Species → standard edges reuse the exact source list already published for each Global WoodIntel Score sub-score.
