UJI 13-1423. Strict products liability; component part.

“Products liability” applies to the supplier of [a component part] [material intended for further processing] which causes injury if, when added to or incorporated into the finished product, the [component part] [material] is substantially unchanged or is in a condition in which it could have been reasonably expected to be used. For substantial change in the [component part] [material] to relieve a supplier of liability, the change itself must be a cause of the harm done.
