What it is
An 18-page standard on showing that an investigative method is fit for purpose: capturing functional and non-functional requirements, describing the method, and producing evidence that the implementation satisfies those requirements. It explicitly addresses how vendor and third-party testing can be folded into your own assurance argument.
Who it is for, and when
This is the standard to reach for when someone challenges your method rather than your handling. Read it before you write a validation plan for a tool or workflow, and read it again if you are relying on a vendor's testing instead of your own. It pairs directly with the UK Forensic Science Regulator's FSR-G-218. It is paywalled: iso.org listed it at CHF 100 in September 2026, and readers should check iso.org for a newer revision before relying on this edition.
What it does not cover
It is guidance on the shape of a validation argument, not a validation protocol — there are no test datasets, no pass/fail criteria and no worked examples. At 18 pages it will not substitute for a discipline-specific validation methodology.

NIST's long-running programme that builds tool specifications, test assertions, test procedures and test data for categories of forensic function — disk imaging, hardware and software write blocking, deleted file recovery, file carving, string searching, media preparation, mobile device and cloud data extraction, Windows registry and SQLite tools — and publishes the resulting test reports with DHS Science and Technology.
A CFTT offshoot that packages NIST's test methodology so labs can run it themselves and optionally share results: distributed as bootable Linux ISOs and a portable Windows web-server build, with report templates. Current suites cover disk imaging, forensic media preparation, hardware write blocking, string searching, SQLite recovery, mobile device acquisition and cloud data extraction, with companion datasets in CFReDS.
