Frequently Asked Questions
How do you inspect hardware accessories before shipment?
Inspection can include material review, size and dimension check, surface finish inspection, function check, logo appearance review and packing check based on confirmed requirements.
Can salt spray testing be arranged?
Yes. Neutral salt spray testing (ASTM B117 / ISO 9227 NSS) is arranged on request. As a reference, the finishes we run typically reach: Nickel 24–48 h, Gold 24–48 h, Gunmetal 48–72 h, Matte Black 72–96 h, Antique Brass 24–48 h, Antique Silver 24–48 h, Brushed Finish 48–96 h (sealed), Painted Finish 72–120 h, Enamel 48–72 h, PVD 120–240 h, Anodized 168–240 h (sealed). Actual hours depend on the base material, coating thickness, part geometry and the failure criterion you specify (first white corrosion, red rust, or a percentage of affected area), so the result for a specific order is confirmed by test report. Per-finish figures, including lead time and minimums, are listed at https://www.eco-hardware.com/materials-finishes/finishes/.
Can tensile testing be arranged for buckles, hooks or rings?
Tensile testing can be discussed for suitable buckles, hooks, rings or attachment structures after application, material, size and test scope are confirmed.
Can nickel-free requirements be reviewed?
Nickel-free requirements can be reviewed when the buyer confirms target market, material, finish and testing scope before sampling.
