I think you are referring to UKFAT 2013 Annex B: Short Range Devices; = Section 15 Inductive Devices

 

Licence exempt means you can operate under  specified conditions = without an individual licence.

 

For the frequency range 60.25-90 kHz UK Licence exempt regulations = have been transposed from European = Commission (EC) Decision 2011/829/EU:

 

http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=3DC= ELEX:32011D0829:EN:NOT

 

The exemption orders (implementing the EC Decision) are in UK = Statutory Instruments (SIs):

 

The Wireless Telegraphy (Exemption) Regulations ( with various = amendments)

 

You can download them here:

 

http://www.legislation.gov.uk/uksi= ?title=3DThe%20Wireless%20Telegraphy%20%28Exemption%29%20Regulations<= o:p>

 

The SI dealing with induction (and frequency range 60.25-90 kHz) is: =  2010 No. 2512

 

For licence exempt operation in the frequency range 60.25 – 90 = kHz with 72 dBuA at 10m  

 

SI 2010 refers to apparatus complying with UK Interface Requirement = IR2030 which requires kit to meet  ETSI European Norm = EN300330

 

You can download UK Interface Requirements = from:

 

http://stakeholders.ofcom.org.uk/spectrum/technical/interface= -requirements/

 

It’s on the second web page

 

IR2030 June 2013 as a PDF

Inductive applications are on page 40

 

ETSI Standards are free of charge you can download EN300330 = from:
