Test specimen design
 
 
It is usually a waste of time to adopt  a piecemeal approach of testing a product because "I need a certificate for the job at XYZ".  XYZ is probably the last time that particular design detail will occur!
The better approach is to test a specimen which is designed to cover as many applications for the product (including the job at XYZ), and more importantly is designed to pass the appropriate test.
