1 Scope

This section provides the basic principles of environmental aspects into product fuses (hereinafter referred to as products).

This section applies to new or improved product design.

This section applies to fuse full-time staff including fuses used (blade contacts circuit breakers, fuses bolted cylindrical cap fuse Breaker), fuses for use by unskilled persons (screw type fuses, fuse tube), protection of semiconductor devices such as fuses.

The purpose of this section is to the product design stage to control its impact on the environment.
