  • requirement for submission of a technical file detailing construction of device
  • revised requirements for smaller devices (defined as “concealable devices”) which are suitable for use by specialist officers
  • specified methods for chemical analysis, which will be conducted as part of the CAST assessments by a CAST‐approved independent test facility
  • limited assessments for inert devices and general exposure (familiarisation training) devices
  • batch testing and quality assurance process through manufacturer quality testing
