Evolv Technology has been asked to change claims its technology has been tested by the government
An AI weapons-scanning company has backtracked on claims its technology has been tested by the UK government.
Evolv told BBC News it had altered its claims about UK testing to "Better reflect the process taken".
The company had said that its AI weapons scanner had been tested by the UK Government's National Protective Security Authority.
On 20 February the company put out a press release, including a claim that the NPSA was one of a number of testers who had "Concluded that the Evolv Express solution was highly effective at detecting firearms and many other types of weapons".
Metrix NDT managing director Nick Fox told BBC News that Evolv's system had indeed been tested against NPSA specifications.
Evolv told the BBC that in addition to those results, Evolv makes available to any serious prospective customer full third-party testing reports for detection performance.
Evolv has previously said its technology detects the "Signatures" of concealed weapons.
In 2022, following a Freedom of Information request by the security-analysis company Internet Protocol Video Market, BBC News revealed that testing by a US facility had found Evolv's technology could not consistently detect knives and certain types of bombs.
Evolv had initially referred to the designation of its technology under the US Department of Homeland Security Safety Act as an example of recent "Third party testing".
Questions remain as to what Evolv has previously told customers its technology is capable of and the testing it has gone through.
