We manufacture stainless-steel jewelry and packaging to recognized international test standards. Documentation for each order is prepared on request — we do not publish generic pass/fail numbers, because results vary by alloy, finish, and batch. Below is how we verify compliance.
Salt Spray (Corrosion) Resistance — ASTM B117
We evaluate corrosion resistance using the ASTM B117 neutral salt-spray method, the industry standard for accelerated corrosion testing. 316L stainless steel and PVD-coated finishes are tested to the duration your destination market or buyer specification requires. Per-order test reports are provided on request.
Nickel Release — EN 1811 / EN 12472 (EU REACH)
For items in direct and prolonged skin contact, we assess nickel release under EN 1811 (and EN 12472 for coated articles, which simulates wear). The EU REACH limit is 0.2 µg/cm²/week. 316L stainless steel is intrinsically low in free nickel at the surface; we verify release per batch against the applicable threshold on request.
PVD Coating Thickness
PVD (Physical Vapor Deposition) coating thickness is measured by XRF spectroscopy or cross-section microscopy. We specify a target micron range per finish and verify coating build on request; the report states the measured value for your ordered finish.
How We Document Compliance
- Every compliance document is tied to a specific order, alloy, and finish — not a generic claim.
- Reports are issued on request to match your market (EU/US) and buyer requirement.
- We do not list standalone “test certificates” on the public site; request them with your RFQ so the numbers match your actual product.
Frequently Asked Questions
Do you provide test reports with orders?
Yes. Compliance documentation is prepared on request and tied to your specific alloy, finish, and batch — not a generic, site-wide claim.
What standards do you test to?
ASTM B117 (salt spray / corrosion), EN 1811 and EN 12472 (nickel release, EU REACH 0.2 µg/cm²/week), and PVD coating thickness via XRF or cross-section microscopy.
Can you meet EU / US compliance for skin-contact jewelry?
Yes. We verify nickel release per batch against the applicable REACH threshold and document the result on request for your market.
Do you publish generic pass/fail numbers?
No. Results vary by alloy, finish, and batch, so we issue per-order documentation rather than generic numbers that would not reflect your actual product.
