Does Automist's electronic nozzle meet BS 8663-1?

BS 8663-1:2019 is a standard designed to validate the robustness of traditional automatic or open (no moving parts) water mist nozzles. Electronic nozzles are neither fully open, nor automatic, nor pre-action nozzles, so the test protocols are not fully compatible with this nozzle type. Plumis have summarised all the first-party (internal) and third-party (external) testing done on its system. The test program was either carried out using BS 8663-1 test protocols or equivalent international certification protocols. Deviations are documented and justified in this document

BS 8458 states in its introduction that ‘the testing and approval of watermist system components for residential and domestic applications is a developing area’. As per FM 5560-2017, page 16: 

“Due to the current state of water mist system technology, a comprehensive absolute standard for the testing of water mist components is not possible. Since each water mist system is unique in its operation and design, the component testing of the water mist system shall be performed on a case-by-case basis.”

We have had to venture to the US and engage with UL to develop component testing for an electronic nozzle, as there was no certification available in the UK and BS 8663 does not cover electronically controlled watermist nozzles.
