As per CPC-2-0-03, compliance with SC6 may be demonstrated by providing one or any combination of the following:
- theoretical calculations
- measurements results
- proof that corrective measures were implemented where needed
Note that for broadcasting undertaking, the specific requirements outlined in section 8 of BPR-1 shall be verified when evaluating SC6.
When calculations are used to show compliance, a description of the mathematical prediction models used must be included in the RF exposure report. In the case of computational evaluations, a description of the software used should also be provided. Figure(s) (displaying north bearing and a scale in the legend to indicate distances) clearly identifying SC6 compliance contours should be provided. Near and far field considerations and a description of how field reflections are being considered must be addressed in the report. See section 5.3.1 for details.
When calculations, using worst case assumptions (methodology outlined in TN-261 or other comparable methods), show that RF exposure levels exceed the uncontrolled environment limits of SC6 in any area accessible to the general public, measurements, or the implementation of permanent mitigation measures restricting public access (see CPC-2-0-20 for details), shall be detailed in the report in order to demonstrate compliance.
When field measurements are used to demonstrate compliance, information such as dates when measurements were taken, weather conditions, and whether transmitters were operating at maximum power at the time of measurement should be noted in the RF exposure report. In addition, the measurement methodology used (i.e. time averaging versus spatial averaging) should be described (see section 5.3.2 for details). When measurements are used to assess compliance of new installations or existing installations being modified, these should be taken immediately after the station is turned on for testing.
A description of each piece of equipment used for measurement, as well as the manufacturer's published uncertainty for the equipment and calibration information of each measurement device (e.g. the accuracy of measurements in dB), should be included. The measurement equipment uncertainty must be added to each measurement point. When the measured value plus the manufacturer’s specified instrument uncertainty factor exceeds the SC6 limits for uncontrolled environments, the site will be considered as non-compliant. In such cases, ISED must be informed immediately and close follow-up is required. Permanent corrective measures shall be implemented for the site to comply with the SC6 requirements. The maximum normalized percentage (%) of the Safety Code 6 limit for uncontrolled environments, as well as their location, should be clearly identified in the report. See section 5.3.2 for details.
The RF exposure report shall conclude with a clear statement related to the SC6 compliance of the site (see annex A for an example).
