What are the six requirements a plaintiff must establish to impose strict product liability?

The six requirements a plaintiff must establish to impose strict product liability are:
• The product must be in a defective condition when the defendant sells it.
• The defendant must normally be engaged in the business of selling that product.
• The product must be unreasonably dangerous to the user or consumer because of its defective condition (in most states).
• The plaintiff must incur physical harm to self or property by use or consumption of the product.
• The defective condition must be the proximate cause of the injury or damage.
• The goods must not have been substantially changed from the time the product was sold to the time the injury was sustained.
