Scope:

1.1        
This International Standard is applicable to devices for surge protection of telecommunications and signalling networks against indirect and direct effects of lighting or other transient overvoltages.

The purpose of these SPDs is to protect modern electronic equipment connected to telecommunications and signalling networks with nominal system voltages up to 1000 (r.m.s) a.c. and 1500 V d.c.

Project need:

To align Canadian requirements with those of international standards in the surge protective devices connected to telecommunications and signalling networks subject area. This proposed New Standard is being developed at the request of Canadian Mirror Committee to TC 108, certification bodies, and the industry. It will provide the industry with a new standard to meet the requirements of new advancement in technology. This will meet the strategic needs of the following key interests: a) ensuring that the latest innovative/technology/safety features are available for users, b) addressing needs of regulators by providing suitable requirements; and   c) supporting certification bodies.
