I think "Boilerplates" here does not mean a physical plate... It refer to a document that would be used for a sample or 雛形 such as 普通取引約款, a kind of a package that you may often see in HTML5, etc. I think English "Boilerplates" is similar to template, but contains more systematic functions or rules. (but maybe depends on each situation and usage)
