"The present document specifies the requirements for Object Discrimination and Characterization Applications for power tool devices operating in the frequency band from 2@2 GHz to 8@5 GHz; Additionally it specifies reduced emissions in the ranges from 0@96 GHz to 2@2 GHz and 8@5 GHz to 10@6 GHz. Equipment covered by the present document operates in accordance with amended ECC Decision ECC/DEC(07)01 on specific Material Sensing devices using Ultra-Wideband (UWB) technology [amended 26 June 2009] [i.5]. The present document applies to: a) UWB object discrimination and characterisation equipment for imaging and object detection applications; b) equipment fitted with an integral antenna; c) Two main categories: 1) Category A: user protection in bentchtop tools / table saws (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.1754 [i.3] 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 the absorptive material such as walls and other building materials which absorb emissions. 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. The present document is intended to cover the provisions of article 3.2 of Directive 1999/5/EC [i.2] (RTTE Directive)@ which states that ""... radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radiocommunications and orbital resources so as to avoid harmful interference""."
