Testing
Mesh count, wire diameter, open area, purity and tensile — measured, not catalogued.
| Property | Method | Result | Where |
|---|---|---|---|
| Mesh count | Optical count over a measured length | Per lot | Report |
| Wire diameter | Laser micrometer | ±0.003 mm | Report |
| Open area | Calculated from count and diameter, checked optically | Per lot | Report |
| Purity | Composition analysis | min 99.5% Ni200 / N6, min 99.0% Ni201 | Certificate |
| Tensile | ASTM E8, annealed | 380 – 690 MPa | Certificate |
Standards
Mesh geometry follows ASTM B456 and the ISO weave standards. Where a customer’s own drawing defines the aperture, the drawing governs and the standard is the fallback.
