| Decision | NCC foil | nickel foil | Acceptance basis | Your input or result |
|---|---|---|---|---|
| Foil layers | Thin copper core with specified nickel surface layers | Thin nickel foil of specified grade and condition | Measure total gauge and each layer separately. | |
| Handling | Layer integrity and exposed cut edges matter during slitting and forming | Nickel foil temper, burr and handling damage matter | Agree flatness, pinhole and edge inspection for the narrow gauge. | |
| Electrical and joints | Evaluate sheet resistance and contact to the nickel surface | Evaluate sheet resistance and contact to nickel foil | Use the same current path, joint stack and test temperature. | |
| Qualification | Confirm foil construction and intended exposure by drawing-specific tests | Confirm nickel grade and intended exposure by drawing-specific tests | Round-wire B355 does not establish foil compliance or a universal temperature limit. |
