What is the difference between an original and a re-certification?
As far as the testing required and number of test samples needed, there essentially is no difference. However a package can only be called a re-certification if it is NOT “different” from a previously tested design type. See CFR 49 178.601(c)(4). By definition, a “different” packaging is one that differs (i.e. is not identical) from a previously produced packaging in structural design, size, material of construction, wall thickness or manner of construction. For exceptions to this rule see 178.601(c)(4)(i-vi).
