On 4 October 2022, the Ministry of Innovation, Science and Economic Development Canada (ISED) released RSS 102 supplement SPR-002, Issue 2.

This document is a supplementary procedure to evaluate the compliance of devices operating at frequencies of 3 kHz to 10 MHz with RSS-102, replacing SPR-002, Issue 1, with a transition period from now until October 4, 2023.

The certification required to use SPR-002,Issue 2, or SPR-002,Issue 1 will be accepted during the transition period (you cannot mix the old and new versions, only one of the two can be used). After October 4, 2023, only applications for certification of equipment using SPR-002,Issue 2, will be accepted and equipment manufactured, imported, distributed, leased, offered for sale or sold in Canada will be subject to this release.

Contents Changed

Change 1

This document is for Type 1 Wireless Power Transmission (WPT) industrial, scientific and medical (ISM) devices.

Change 2

Reference documents included in IEC/IEEE 62704-1 and 62704-4 are used as part of the basis for computational evaluation methods.

Change 3

Relaxation factors for limb exposure in the assessment were revised according to the reference level:

In the case of floor and walking devices, the foot relaxation coefficient can be applied from 0cm to 10cm. Leg relaxants can be applied from 10cm to 85cm. The relaxation coefficient should not be used beyond 85 cm.

For ground equipment that is obstructed by objects (i.e., the general public cannot walk on the equipment during operation), the leg relaxation coefficient can be applied to heights up to 85 cm. The relaxation coefficient should not be used beyond 85 cm.

Change 4

According to the RF exposure limit, the reference level and basic limit are added for the assessment. The reference level and basic limit include the assessment based on measurement and calculation. The assessment process is as follows:

Canadian Wireless Power Transmission Standard content changes

Change 5

Reference level measurement based detection requires that the detector should be approved by the laboratory for probe sensitivity, probe level corresponding, probe linear range and linear error calibration.

Change 6

An annex has been added that provides specific and detailed requirements for wireless power transmission implementation, focusing on portable devices and electric vehicle charging.

To ensure the safety of radio products on the Canadian market, local regulations require a licence to be licensed as ISED to be sold on the Canadian market.

The certification covers products such as telecommunications equipment, radio and television equipment, information technology equipment, radio equipment and so on. If you have any other questions, to learn more about the content of detection and certification, please consult the LCS Commissioner!
