Jewellery testing is not just about checking shine and durability; it’s about ensuring products meet strict global standards to withstand real-world conditions. Sweat, sulphur gases, UV light, humidity, salt spray, and water immersion all challenge jewellery materials. Recently, a client approached LIB for a multi-environment test chamber capable of simulating these conditions within a compact setup. Here’s how LIB translates these complex needs into practical, standards-based solutions.
Jewellery often faces daily exposure to harsh conditions. To maintain quality and brand reputation, testing must follow recognized benchmarks. The client listed several key standards, each addressing a unique stress factor:
· ISO 105-E04 – Synthetic Perspiration / Sweat Test ensures jewellery resists tarnish and corrosion in contact with sweat. This involves artificial sweat solutions, 30–45 °C temperatures, and high humidity (≥90% RH) with spray or immersion.
· ASTM B809 – Sulphide / Tarnishing Test evaluates tarnishing resistance by exposing jewellery to low concentrations (0.1–10 ppm) of corrosive gases like H₂S or SO₂.
· ISO 4892-2 – UV Exposure & Weathering simulates sunlight and moisture, using UV-A/UV-B lamps, 25–70 °C temperature, and condensation cycles to measure fading and surface changes.
· ASTM B117 / ISO 9227 – Salt Spray & Cyclic Corrosion subjects jewellery to salt fog and wet/dry cycles to check corrosion resistance in coastal or humid environments.
· Humidity & Temperature Aging maintains samples at 20–70 °C and 40–100% RH to evaluate long-term stability.
· Immersion & Cyclic Exposure in Different TDS Waters checks how jewellery performs in water of varying mineral content, both static and in cycles.
Each standard adds a layer of assurance, proving that jewellery can maintain beauty and structural integrity in real-world use.
A single chamber performing all these tests is technically challenging. Different gases, solutions, and temperatures require careful separation to avoid contamination. LIB’s strategy is to combine compatible environments and create dedicated modules for specialized tests:
Temperature, Humidity, and UV Weathering can work together. LIB’s Temperature & Humidity Chambers and UV Weathering Testers handle ISO 4892-2 and similar requirements in one programmable system.

Sulphide and SO₂ Corrosion demand corrosion-proof builds. LIB’s H₂S Corrosion Chambers and SO₂ Test Chambers meet ASTM B809 while protecting samples and operators.

Salt Spray & Cyclic Corrosion need isolation. LIB’s Salt Spray Chambers
· are proven for ASTM B117 and ISO 9227.
· Immersion Testing can be added as a bench-top module, controlled via the same interface for seamless operation.

This modular design keeps systems compact, flexible, and standard-compliant, giving labs the freedom to test comprehensively without unnecessary complexity.LIB not only provides a full range of standardized chambers but also has extensive customization experience to meet unique client needs.
LIB focuses on ease of use and reliability:
- Fully Programmable Controls with touchscreen interface and USB/Ethernet data export.
- Durable Materials like stainless steel or ceramic liners resistant to corrosion and UV.
- Safety Systems for over-temperature cut-off and gas exhaust.
- Global Service including calibration and support in India and worldwide.
Q1: Can LIB combine all tests in one chamber?
Not entirely. Some tests, like salt spray and sulphide exposure, require isolation, but LIB integrates compatible conditions (UV, temperature, humidity) in one unit and adds modules for others.
Q2: Are LIB products compliant with standards?
Yes. Equipment is designed to meet ISO 105-E04, ASTM B809, ISO 4892-2, ASTM B117, ISO 9227, and more.
Q3: What about warranty and support?
LIB provides a 3-year warranty and lifetime service support, including calibration and training.
Q4: Can LIB supply and service in XX?
Absolutely. LIB offers delivery, installation, and after-sales service.
