The Commonwealth Scientific and Industrial Research Organisation runs the Fire Technology Laboratory at North Ryde in Sydney, NATA-accredited (165, site 3625) for reaction to fire, fire resistance and bushfire testing to the AS 1530 series — walls, floors, doors, dampers, shutters, ducts, columns, roofs, ceilings, penetration seals, windows and glazing. It also operates ActivFire, the listing scheme for active fire products that Australian specifications name directly. On any measure it is the country’s most significant fire laboratory, and it is here because the directory’s bar is whether accredited testing is sold on the open market rather than who owns the laboratory: CSIRO is a Commonwealth statutory agency. One thing to check before relying on it: the North Ryde site has been under a closure question, and CSIRO has agreed a temporary lease extension keeping the Fire Testing Laboratory running to the end of the 2026–27 financial year. Confirm current capacity before planning a test programme around it.
