Why corrosion testing matters for ball chains
JOVIS is an experienced European ball chain and bead chain manufacturer combining high-capacity integrated production with disciplined quality assurance. Our professional team conducts periodic corrosion checks in our in-house test laboratory to evaluate product and coating consistency.
In-house salt spray laboratory and process control
Salt spray (fog) exposure helps reveal coating pores, surface deterioration, red rust on susceptible steel and changes to metallic finishes. Where specified, the test method follows ISO 9227 or ASTM B117; exposure hours, acceptance limits and test frequency are agreed by product and customer. In-house checks can be complemented by accredited third-party laboratory testing when requested.
Roller blinds, dog tags, keychains and outdoor applications
Roller blind and curtain operating chains face frequent hand contact, humidity, condensation and sometimes window-side moisture. Dog tag chains and pet accessories can encounter rain, sweat and outdoor dirt. Keychains, bag chains and decorative accessories face skin oils, handling and abrasion. Lighting pull chains, plumbing and bathroom accessories may experience damp environments. Industrial and display chains require application-specific corrosion control.
Materials, coatings and customer-specific requirements
Nickel-coated steel, stainless steel and brass have different corrosion behaviours. Base material, coating thickness, finish integrity, cut ends, connectors, storage and cleaning affect performance. Periodic sampling, traceable test conditions and agreed acceptance criteria help identify deviations before shipment; testing supports quality control but cannot guarantee a corrosion-free lifetime.

FAQ
Does salt spray testing predict years of outdoor service? No: it is an accelerated, controlled quality-control method, not a direct service-life forecast. Are all ball chains equally resistant? No: resistance depends on alloy, finish and environment. Can JOVIS arrange independent tests? Customer-requested accredited testing can be arranged by agreement.
