Test data library
Specifiers, procurement teams and increasingly their software read published material data directly. Data locked inside a PDF is invisible to all of them. Everything here is published as structured, machine-readable data with the method and the uncertainty attached — because a number without its mounting condition is not a result, it is a rumour.
Publication and confidentiality
Nothing is published here without the client's written permission. Where permission is given for the data but not the identity, results are published anonymised by product category and construction, never by brand.
