Indirect mechanical stress that develops in structures or piping due to thermal expansion, settlement, or equipment movement. Unlike primary stress, it isn't caused by direct applied loads. Subcontractors must account for it during installation and inspection to avoid material fatigue and warranty disputes.

Products created by processing or transforming raw materials supplied under a contract, such as fabricated components or treated fluids. Subcontractors must clarify ownership rights over derivative goods before work begins. Contracts often assign these rights to the prime contractor or client by default.
