Standards & norms
European standards, surface-treatment grades, glass classes and planning references used in PONARC specification work — grouped by topic, linked straight to the deep-dive article or the live calculator.
MAY 2026 REVIEW NOTE
Standards references are routing notes, not blanket approvals
PONARC uses this hub to connect EN 1991, EN 13561, EN 14501, glass, acoustic and surface-treatment references to the right project checks. Final edition, national annex, load case and approval route are confirmed per project before release.
- • Check the destination country and national annex.
- • Confirm wind, snow, glass, fixing and operating assumptions.
- • Treat energy, shading and acoustic references as calculation inputs, not universal guarantees.
