ISO 17025 (testing & calibration laboratories)

The demand curve

Notices demanding it per 10,000 published, by year — rate-normalised so corpus growth never masquerades as demand. Complete years only.

The pale bars are 2025 onward. The Procurement Act went live on 24 February 2025 and changed how notices are written, so the step across that date is partly a change in convention and not only a change in demand. We have not measured how much of it is which, so please do not read this as a trend.
