RM5706 SO9885 Electromagnetic Compatibility (EMC) Standard

Tender description

Before being used by the police, all breath alcohol equipment must be type approved by the Secretary of State for the Home Office. This requires it to pass a series of tests mandated by guides to type approval for each piece of equipment (evidential testers or screeners). This includes some environmental testing, including radio frequency interference. Starting in 2016, UK emergency services is likely to begin migration from the current TETRA (Terrestrial Trunked Radio) system, to a proposed 4G LTE (4th Generation Long-Term Evolution) based system, referred to as the ESN (Emergency Services Network). This will result in a very different electromagnetic landscape that will look vastly different from when the current standards were drafted. Current EMC requirements are outlined in three separate Home Office Standards (Spec 5, FSS and Speedmeter Handbook) and CAST requires that these must be consolidated in a single updated EMC standard. The current standards can be found at annexes 1-5.
