27、netic compatibility and Radio spectrum Matters (ERM). Equipment covered by the present document operates in accordance with amended ECC Decision of 30 March 2007 on specific Material Sensing devices using Ultra-Wideband (UWB); technology (ECC/DEC/(07)01), amended 26 June 2009 (ECC/DEC/(07)01 5). For
28、 non EU countries the present document may be used for regulatory (Type Approval) purposes. The present document is part 1 of a multi-part deliverable covering Ultra WideBand (UWB) Discrimination and Characterization Applications for power tool devices operating in the frequency band from 2,2 GHz to
29、 8,5 GHz; as identified below: Part 1: “Technical characteristics and test methods“; Part 2: “Harmonized EN covering the essential requirements of article 3.2 of the R b) equipment fitted with an integral antenna; c) Two main categories: 1) Category A: user protection in bentchtop tools/table saws (
30、quasi fixed sawing equipment). 2) Category B: breakthrough protection in drilling devices. The present document does not apply to: UWB communication devices; and Ground penetrating radar devices; and through-wall radar imaging devices; building material devices; as defined in ITU-R Recommendation SM
31、.1754 i.1 and EN 302 435-1 i.6. The present document specifies the equipment which is designed to not radiate into the free space. It is designed to function only when positioned such that it radiates directly into: a) free space (for category A equipment); or b) to the absorptive material such as w
32、alls and other building materials which absorb emissions for category B. The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable. 2 References References are either specific (ident
