Extraction notes & caveats

A1/A2/A3 reported individually plus an A1-A3 aggregate. A4 and A5 ARE declared here (Cradle to gate with options, A4-A5, C1-C4, D). B1-B7 are ND (not declared). C1-C4 and D declared. All core EN 15804+A2 GWP modules (A1-A3, A4, A5, C1-C4, D) are on a single results page (p.8); GWP-GHG on p.11. GWP-total A1-A3 prints 310 while GWP-fossil A1-A3 prints 309 despite identical printed A1/A2/A3 splits (270/36.1/3.65 sum to 309.75) — source rounding. A dual EN 15804+A1 / CML GWP table also appears on p.10 (not captured; dataset standardises on +A2). GWP-total = GWP-fossil + GWP-biogenic + GWP-luluc holds per module within source rounding. Strength 50 MPa derived from strength class N50 and product description 'characteristic strength of 50MPa'.
