Overview
The HAIDA INTERNATIONAL Leather Colorfastness Tester is a purpose-built instrumental system designed to evaluate the resistance of leather and leather-like materials to color change or dye migration under controlled exposure to light, heat, humidity, and mechanical abrasion. Engineered for precision and repeatability in quality control laboratories, this tester operates on standardized accelerated aging principles—primarily simulating xenon arc or UV radiation exposure (per ISO 105-B02, ISO 105-B04, ASTM D2244, and GB/T 8427)—to quantify chromatic shift (ΔE*ab), fading severity, and staining potential against adjacent materials. Its robust architecture supports both continuous irradiance monitoring and programmable exposure cycles, enabling correlation between laboratory test duration and real-world service life under varying climatic conditions.
Key Features
- Modular optical chamber with calibrated xenon arc lamp source (optional UV fluorescent lamp configuration available), compliant with CIE No. 85 spectral power distribution requirements for daylight simulation
- Integrated temperature and relative humidity control (range: 20–60°C; RH 30–75%, ±2% accuracy) to replicate diverse environmental stress profiles
- Standardized sample holder accommodating multiple leather specimens (up to 5 × 10 cm per slot) with consistent clamping pressure and exposure geometry
- Digital timer with multi-stage programming capability (up to 999 hours cumulative exposure), supporting intermittent dark/light cycles and ramped intensity profiles
- Compliant with ISO/IEC 17025 traceability framework; all irradiance sensors calibrated annually against NIST-traceable reference standards
- Stainless-steel interior housing with corrosion-resistant finish, CE-marked electrical safety compliance, and integrated ventilation with ozone exhaust management
Sample Compatibility & Compliance
The tester accommodates full-grain, corrected-grain, suede, nubuck, synthetic leathers, and coated textile substrates used in footwear, upholstery, automotive interiors, and luggage applications. It supports standard test configurations including AATCC TM16, ISO 105-B02 (xenon arc), ISO 105-B04 (xenon arc with water spray), and GB/T 8427–2013. All operational parameters—including irradiance output (W/m² @ 340 nm), black panel temperature (BPT), and chamber humidity—are continuously logged and verifiable for GLP/GMP audit readiness. The system meets functional requirements for ISO 9001:2015-certified laboratories and aligns with regulatory expectations for pre-market material qualification under EU REACH Annex XVII and US CPSC guidelines for consumer product safety.
Software & Data Management
The HAIDA Leather Colorfastness Tester operates via embedded firmware with optional PC-based control interface (HAIDA TestSuite v3.2). Data acquisition includes real-time irradiance, chamber climate, elapsed exposure time, and user-defined pass/fail thresholds. Export formats include CSV and XML for integration into LIMS environments. Audit trail functionality records operator ID, parameter changes, calibration events, and test initiation/termination timestamps—fully compliant with FDA 21 CFR Part 11 requirements when configured with electronic signature modules. Raw spectral data can be imported into third-party color analysis platforms (e.g., X-Rite Color iQC, Datacolor MATCHTEXTILE) for ΔL*, Δa*, Δb*, and CMC(2:1) calculations.
Applications
- Quality assurance of dyed and pigmented leathers prior to mass production release
- Comparative evaluation of dye stability across tanning methods (chrome, vegetable, aldehyde)
- Validation of protective coatings and finishing agents against photolytic degradation
- Supporting technical documentation for ISO 14001 environmental management systems through material lifecycle impact assessment
- Root cause analysis of field failures related to color migration in bonded assemblies or multi-material laminates
- Pre-compliance testing for certification bodies including SGS, BV, and TÜV Rheinland
FAQ
What standards does this instrument support out-of-the-box?
It natively supports ISO 105-B02, ISO 105-B04, ASTM D2244, AATCC TM16-2021, and GB/T 8427–2013. Optional firmware updates extend coverage to EN ISO 105-X12 and JIS L 0841 upon request.
Is calibration documentation provided with shipment?
Yes—each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China) and includes a 12-month calibration verification schedule.
Can the system be integrated into an existing lab network?
Yes—Ethernet and RS-232 interfaces support remote monitoring, centralized data aggregation, and automated report generation via OPC UA or Modbus TCP protocols.
Does the instrument meet requirements for accredited testing laboratories?
Yes—it satisfies ISO/IEC 17025:2017 clause 6.4 (equipment) and clause 7.7 (test method validation) when operated within specified environmental tolerances and maintained per HAIDA’s scheduled service protocol.
