Simple situations where testing materials makes sense:
New Material or Supplier
- First time using a new material type
- Changed to a new supplier
- Want to verify claims before big order
Something Seems Off
- Parts don't perform as expected
- Color, feel, or weight seems different
- Price is suspiciously low
- Quality issues appearing
Compliance & Regulations
- Need proof for regulations (RoHS, REACH, etc.)
- Customer asks for material certificates
- Checking recycled content claims
- Food contact or medical use requirements
