scope:

The present document specifies the requirements for Object Discrimination and Characterization Applications (ODC) for power tool devices using UWB technology operating in all or part of 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.

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.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 walls 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.
