Section 67 of 105
65. Manufacturer Independence and Interchangeability
Stable section ID: S05-CON-014-SECTION-67 · 24 content blocks
System05 Interfaces shall support qualified implementations from independent manufacturers.
Manufacturer independence requires that essential compatibility not depend on:
- Undisclosed proprietary geometry.
- Exclusive software services.
- Manufacturer-only installation tools without justified need.
- Hidden authentication dependencies.
- Unavailable maintenance information.
- Uncontrolled licensing conditions.
- Commercial identity rather than engineering evidence.
Interchangeability shall require more than nominal dimensions. A replacement asset shall satisfy applicable requirements for:
- Form.
- Fit.
- Function.
- Capacity.
- Safety.
- Durability.
- State behavior.
- Environmental performance.
- Maintainability.
- Digital identity.
- Verification and evidence.
Manufacturers may provide proprietary internal improvements or optional capabilities, but these shall not obstruct mandatory Interface behavior or create avoidable vendor lock-in for essential building functions.
Equivalent products may use different materials and manufacturing processes when they remain within the same verified compatibility and performance envelope.
No manufacturer shall be permitted to redefine a shared Interface unilaterally.
