Long-lasting aesthetic integrity is essential for active lifestyles. This feature ensures that jewelry and accessories resist the corrosive effects of perspiration, providing a benchmark for high-performance functionality.
The Science of Sweat Resistance
In the jewelry industry, sweatproof performance is the measure of a material's "corrosion resistance" against synthetic body fluids. Human sweat contains a complex mixture of water, lipids, and salts (sodium chloride), which can act as an electrolyte to trigger "galvanic corrosion" or tarnishing. For high-performance jewelry, this resistance is achieved by using noble metals (like gold or platinum), marine-grade stainless steel, or advanced Physical Vapor Deposition (PVD) coatings. PVD coating involves bonding a thin, incredibly hard layer of decorative metal to the base material in a vacuum, creating a surface that is chemically inert and won't flake, green, or dull even after intense physical activity.
Validation through the High Performance Mark
By meeting selected technical benchmarks, your jewelry products become eligible for the Intertek High Performance (HP) Mark’s Sweatproof. For the Sweatproof claim, we test to ISO 12870 section 4.7. Samples are conditioned in a perspiration solution at 55°C for 24 hours. The samples must display no sign of degradation or surface damage to meet our requirement.
This mark serves as a ‘proof of performance’ by validating that your product meets the HP Mark standards. You can display the mark on product tags, brochures, packaging, websites, and in both online and offline stores across multiple channels, confidently signal to consumers that the performance claims of your products are verified.
