IEEE 1528-2013 Latest Edition
Industry Canada's RSS-102 – RF exposure compliance for radio communication equipment (all frequency bands) includes references to the international standard IEEE 1528. Section 3 of Version 4 of RSS - 102 states:
SAR evaluation shall be conducted in accordance with the latest version of IEEE 1528 and/or IEC 62209.
On September 6, 2013, IEEE 1528-2013 authorized the IEEE Recommended Practice for Peak Spatial Average Specific Absorption (SAR) of wireless communication equipment used near the human head: the measurement technology was published by IEEE Standards Organization.
( http://www.techstreet.com/ieee/products/vendor_id/4418 )
Industry Canada will allow a transition period to adopt the latest IEEE standards.
Before December 1, 2013, Industry Canada will evaluate the SAR compliance of equipment used near the head according to IEEE 1528-2003, IEC 62209-1 Ed. 1 or IEEE 1528-2013. After December 1, 2013, only IEEE 1528-2013 standards will be used for SAR compliance assessment of devices used near the head.
Note: During the transition period, when performing SAR compliance assessment on equipment used near the head, Industry Canada will not accept the use of different standards (such as IEEE 1528-2003 system calibration and IEEE 1528-2013 SAR measurement protocol). Testing will only be conducted according to one standard, not a combination of multiple standards.
2) Power exemption limit
When determining whether a routine evaluation is required, refer to the power exemption limits for routine evaluation specified in Section 2.5 of Version 4 of RSS-102.
However, the department will also accept the power exemption limit based on the draft version 5 of RSS-102. After the release of the fifth version of RSS - 102, only the power exemption limit in that version will be used.
2.5.1 Exemptions from routine assessment - SAR assessment
If the separation distance between the user and/or bystander and the antenna and/or radiation unit of the equipment is less than or equal to 20 cm, SAR assessment will be required, except for the applied output power (including the power tolerance of the equipment) when the equipment operates at or below the separation distance specified in Table I.
Table 1: SAR Assessment - Exemptions for routine assessment based on frequency and interval distance 1

450 | 52 mW | 70 mW | 88 mW | 106 mW | 123 mW |

Spacing distance is 30mm | The spacing is 35mm | The spacing is 40mm | The spacing is 45mm | Spacing distance ≥ 50mm | |
≤300 | 223 mW | 254 mW | 284 mW | 315 mW | 345 mW |
450 | 141 mW | 159 mW | 177 mW | 195 mW | 213 mW |
835 | 80 mW | 92 mW | 105 mW | 117 mW | 130 mW |
1900 | 99 mW | 153 mW | 225 mW | 316 mW | 431 mW |
2450 | 83 mW | 123 mW | 173 mW | 235 mW | 309 mW |
3500 | 86 mW | 124 mW | 170 mW | 225 mW | 290 mW |
5800 | 56 mW | 71 mW | 85 mW | 97 mW | 106 mW |
The output power level shall be the greater of the maximum conducted output power or equivalent omnidirectional radiated power (e.i.r.p.) averaged over time based on the source. For a controlled device, the limit of 1g tissue fluid SAR is 8W/kg, and the exemption limit for routine evaluation in Table 1 should be multiplied by a factor of 5. For equipment suitable for 10 g limb wear, the exemption limit for routine evaluation should be multiplied by a factor of 2.5. If the operating frequency of the equipment is between the two frequencies in Table 1, the exemption limit shall be calculated by linear interpolation at the corresponding interval distance. For tests with an interval of less than 5 mm, refer to the exemption limit with an interval of 5 mm to determine whether a routine evaluation is required.
For medical implant equipment, the exemption limit for routine evaluation is set at 1mW. The output power of medical implant equipment is determined as the larger value of conduction power or effective omnidirectional radiation power to determine whether the equipment is exempt from SAR evaluation.
The exemption limit in Table 1 is based on the measurement and simulation of the half wave dipole antenna at a distance of 5 mm to 25 mm from the plane phantom, and the SAR value in 1g tissue fluid is about 0.4 W/kg. The exemption limit of low frequency (300MHz to 835MHz) comes from linear fitting. The exemption limit for high frequencies (above 1900 MHz) comes from a third-order polynomial fitting.
