NP1 — The reference specification for
monetary-grade nickel wire
NP1 is a precisely-specified grade of nickel wire used as the technical reference for monetary-grade nickel custody arrangements. This page is the canonical source for the NP1 definition: purity, geometry, and the independent validation methods that constitute conformance.

NP1 is a precisely-specified grade of nickel wire: 99.99% purity, 0.025 mm diameter, validated via ICP-MS, ASACERT, and NSL Analytical methods. NP1 specification is the technical reference for monetary-grade nickel custody arrangements.

Independent validation methods
Conformance to the NP1 specification is established via three independent methods, applied in combination. No single test is sufficient on its own; the trio constitutes the technical reference standard.
| Method | Measures | Independent of |
|---|---|---|
| ICP-MS Inductively Coupled Plasma Mass Spectrometry | Elemental purity to ppb resolution. Confirms 99.99% nickel-by-mass and impurity envelope (Cu, Co, Fe, S, C, etc.). | Mechanical/dimensional methods. |
| ASACERT Independent material certification (Manchester, UK) | Material identity, dimensional tolerance, lot-level conformance documentation. | Lab-only chemical assays. |
| NSL Analytical Wet-chemistry & spectrographic confirmation | Cross-laboratory confirmation of purity and trace-element profile via independent assay protocols. | Single-instrument bias. |
Each lot covered by the NP1 specification carries documentation under all three methods. Assay outputs and certification packets are held in the evidence locker; integrity is verified by SHA-256 digest in the manifest.
Independent verification
The NP1 specification is maintained as a technical reference, not a marketing claim. Every parameter on this page is verifiable against primary-source documentation:
- Elemental purity is established by ICP-MS reports issued by the testing laboratory and held in the evidence locker.
- Dimensional and material conformance is independently certified by ASACERT (Manchester, UK).
- Cross-laboratory confirmation is provided by NSL Analytical, using independent wet-chemistry and spectrographic protocols.
- Document integrity is enforced by SHA-256 digests recorded in the public manifest at
/api/evidence-manifest.json.
No claim on this page rests on internal assertion alone. Each is anchored to an independently issued document, recorded with a verifiable cryptographic digest, and held in custody under documented chain-of-custody procedures.
