This law defines a 'building component' as any part or system meant for use in a building, such as structural, electrical, mechanical, plumbing, and fire protection systems, which impact health and safety. However, it specifically excludes appliances like heaters, stoves, refrigerators, or air conditioners that have been certified by an approved testing agency.
