3. l radiators If the equipment complies with the requirements in another relevant standard e g EN 50371 covering low power equipment then the requirements of this standard IEC 62311 are considered to be met and the application of this standard to that equipment is not necessary The frequency range covered is 0 Hz to 300 GHz The object of this generic standard is to provide assessment methods and criteria to evaluate such equipment against basic restrictions or reference levels on exposure of the general public related to electric magnetic and electromagnetic fields and induced and contact current 1 2 COMPLIANCE CRITERIA The electronic and electrotechnical apparatus shall comply with the basic restriction as specified in Annex II of Council Recommendation 1999 519 EC The reference levels in the Council Recommendation 1999 519 EC on public exposure to electromagnetic fields are derived from the basic restrictions using worst case assumptions about exposure If the reference levels are met then the basic restrictions will be complied with but if the reference levels are exceeded that does not necessarily mean that the basic restrictions will not be met In some situations it will be necessary to show compliance with the basic restrictions directly but it may also be possible to derive compliance criteria that allow a simple measurement or calculation to demonstrate compliance with the basic restriction Often these compliance criteria ca
