The NSPE stresses the importance of licensing and makes several points about the seal being important.
Only a licensed engineer may prepare, sign and seal, and submit engineering plans and drawings to a public authority for approval, or seal engineering work for public and private clients.
Only a licensed engineer, for instance, may prepare, sign, seal and submit engineering plans and drawings to an public authority for approval, or to seal engineering work for public and private clients.
Only PEs can sign and seal engineering drawings;
However, I'm having trouble understanding specifically when a seal is required and who or what enforces necessary use of the seal. Is there a general approach for this across any given discipline or project?
I could imagine these sources of "rules" for using a seal.
- Insurance requirements
- Other contractual obligations
If the question is too broad and needs to be narrowed, here's an example...
I worked on an FDA regulated Class III medical device. I read the relevant titles/sections of the CFR and do not recall any mention of using the PE seal. I do not recall any of our hardware design documents or outputs being sealed. I worked on the device control software and I know that none of our software designs, design controls, or outputs were sealed.
