Overview
The Karrie KA-001 Copper Corrosion Standard Color Scale Board is a precision reference tool engineered for visual assessment of copper strip corrosion in petroleum and liquefied petroleum gas (LPG) samples, in strict accordance with internationally recognized test standards—including GB/T 5096 (China), ASTM D130 (USA), and IP 154 (UK). This color scale board replicates the full spectrum of copper surface degradation—from slight tarnish to severe pitting and discoloration—using high-fidelity chromatic reproduction techniques. Unlike photographic or digitally printed references, the KA-001 employs stable pigment formulation and calibrated spectral matching to ensure long-term consistency under controlled storage conditions. Its primary function is to serve as a traceable visual comparator during post-immersion evaluation, where test copper strips are rinsed, dried, and matched against the standardized color gradients under defined lighting and viewing geometries. The board’s metrological integrity is maintained through rigorous adherence to the physical reference methodology specified in ASTM D130 Annex A1, which mandates periodic verification against newly acquired, light-protected master standards.
Key Features
- Manufactured to replicate the original ASTM D130/IP 154 copper corrosion rating scale, covering Class 1a (slight tarnish) through Class 4 (severe corrosion)
- Embedded in rigid, UV-stabilized acrylic substrate to prevent warping, scratching, and environmental degradation
- Each color patch is individually calibrated using spectrophotometric validation against NIST-traceable reference materials
- Reverse-side labeling includes multilingual instructions (English/Chinese) for proper handling, inspection, and replacement criteria
- Supplied with protective opaque sleeve and desiccant pouch to minimize photochemical aging during storage
- Designed for use in ambient laboratory environments compliant with ASTM D130 Section 7.2: illumination requirements (diffuse daylight or equivalent CIE Standard Illuminant D65, 100–200 lux)
Sample Compatibility & Compliance
The KA-001 is validated exclusively for use with copper strips prepared per ASTM D130 Section 5 (electrolytic copper, 99.9% minimum purity, 12.7 mm × 19.1 mm × 1.5 mm) after immersion in petroleum distillates, jet fuels, diesel, gasoline, lubricating oils, and LPG fractions. It supports compliance workflows required under ISO/IEC 17025-accredited testing laboratories and aligns with quality control protocols referenced in API RP 500, ASTM D323, and SH/T 0232. While the board itself is not an analytical instrument, its correct application is mandatory for reporting results in regulatory submissions to CNPC, Sinopec, PetroChina, and international refining partners. Users must document board lot number, calibration date, and last verification date in their LIMS or paper-based QC records to satisfy GLP audit requirements.
Software & Data Management
As a passive optical reference standard, the KA-001 does not incorporate embedded electronics or software interfaces. However, it integrates seamlessly into digital laboratory workflows via structured documentation protocols: users may assign unique asset IDs in CMMS or LIMS platforms (e.g., LabWare, STARLIMS), log verification events against ISO/IEC 17025 Clause 6.4.10, and attach timestamped photographic evidence of side-by-side comparisons using calibrated imaging systems (e.g., DS-Ri2 microscope camera with ICC-profiled white balance). For FDA-regulated facilities, the board’s usage history—including storage logs, replacement triggers, and observer signatures—must be retained for minimum periods stipulated under 21 CFR Part 11 for manual recordkeeping systems.
Applications
- Quality assurance of hydrocarbon fuels prior to pipeline injection or marine bunkering
- Monitoring additive package stability in lubricant formulations during accelerated oxidation testing
- Verification of sulfur compound removal efficiency in hydrotreating units
- Third-party conformity assessment for EN 590, ASTM D975, and GB 17930 fuel specifications
- Training and inter-laboratory proficiency testing for ASTM D130 methodology accreditation
FAQ
How often should the KA-001 color scale board be replaced?
Replace the board immediately upon detection of any visible fading—particularly in the Class 1a and 1b patches—or when the acrylic substrate exhibits >3 discernible scratches ≥0.5 mm in length within the viewing area.
Can the KA-001 be used under artificial LED lighting?
Yes—provided the light source meets CIE illuminant D65 spectral power distribution (SPD) and maintains uniformity across the viewing field (±5% irradiance variance); avoid cool-white LEDs with CCT >6500 K and poor R9 rendering.
Is this board certified by an accredited body?
The KA-001 is supplied with a Certificate of Conformance referencing ASTM D130 and GB/T 5096; formal ISO/IEC 17025 calibration certification is available upon request for batch-specific spectrophotometric validation.
What is the recommended storage temperature range?
Store between 15 °C and 25 °C at relative humidity ≤60%, in the provided light-tight sleeve; avoid exposure to ozone-generating equipment or solvent vapors.
Does Karrie provide technical support for ASTM D130 method implementation?
Yes—application engineers offer remote method validation assistance, including copper strip preparation troubleshooting, lighting setup verification, and internal audit checklist development.
