Overview
The SETA 11405-0 Copper/Silver Strip Corrosion Test Bath is a precision-engineered thermal immersion system designed for standardized evaluation of petroleum product corrosivity toward copper and silver test strips. It operates on the principle of controlled, uniform heating of test specimens immersed in conditioned oil or water bath media, enabling reproducible exposure conditions required by internationally recognized corrosion test methods. The instrument maintains temperature stability within ±0.1 °C across its full operating range (ambient +5 °C to 150 °C), ensuring strict adherence to thermal protocol requirements specified in ASTM, ISO, IP, and national standards. Its robust stainless-steel construction, PID-controlled heating system, and calibrated digital temperature display support long-term operational reliability in QC laboratories conducting routine fuel and lubricant quality assurance.
Key Features
- Precise temperature control with ±0.1 °C accuracy over a wide range (ambient +5 °C to 150 °C), verified traceably to NPL/UKAS-accredited references
- Modular test rack configuration supporting up to nine independent test positions—enabling parallel assessment of multiple samples or replicate strips per test
- Dual-bath compatibility: optimized for both oil-based (e.g., mineral oil) and aqueous media, with dedicated temperature calibration profiles for each medium type
- 1500 W high-efficiency heating element with overtemperature cut-off and thermal fuse protection meeting IEC 61010-1 safety requirements
- Front-panel digital controller with real-time temperature readout, setpoint memory, and ramp/soak programming capability for multi-step test protocols
- Corrosion-resistant chamber housing and removable test racks facilitate cleaning, validation, and compliance with GLP documentation practices
Sample Compatibility & Compliance
The SETA 11405-0 accommodates standard ASTM/ISO copper strip (ASTM D130, ISO 2160) and silver strip (ASTM D4048, IP 611) specimens, as well as custom-length strips up to 75 mm × 12.5 mm × 1.5 mm. Its design conforms fully to mechanical and thermal specifications outlined in all referenced standards—including bath depth, immersion depth tolerance (±1 mm), and agitation requirements (where applicable). The unit supports audit-ready operation under ISO/IEC 17025-accredited testing environments and integrates seamlessly into laboratories maintaining FDA 21 CFR Part 11–compliant data integrity frameworks when paired with validated external logging systems.
Software & Data Management
While the 11405-0 operates as a standalone benchtop instrument, its analog output (0–10 V or 4–20 mA optional) enables connection to laboratory data acquisition systems (e.g., LabVIEW, DeltaV, or custom SCADA platforms) for automated temperature logging and alarm triggering. Users may implement electronic record retention using time-stamped CSV exports from compatible DAQ hardware, satisfying ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) for regulatory submissions. Firmware updates are performed via secure USB interface, with version history and calibration certificate metadata stored internally for traceability.
Applications
- Corrosivity screening of gasoline, diesel, jet fuel, biodiesel blends, and base oils per ASTM D130 and ISO 2160
- Evaluation of sulfur-containing compounds and organic acids in refinery streams using silver strip methodology (ASTM D4048, IP 611)
- Stability testing of fuel additives and antioxidant packages under accelerated thermal stress
- Third-party verification of compliance with EN 590, ASTM D975, and ASTM D1655 specifications
- Supporting root-cause analysis in field failures involving copper/brass component degradation in fuel systems
FAQ
What standards does the SETA 11405-0 directly support?
It is engineered and factory-validated for full conformance with ASTM D130, ASTM D4048, ISO 2160, IP 112, IP 154, IP 611, GB/T 5096, and SH/T 0023—covering both copper and silver strip corrosion test procedures.
Can the bath be used with water instead of oil?
Yes—the system supports both oil and water as bath media; however, temperature calibration curves and maximum operating limits differ between media types and must be selected accordingly per method requirements.
Is the unit suitable for GMP-regulated environments?
When operated with documented calibration, preventive maintenance logs, and integrated with compliant data capture systems, the 11405-0 meets foundational requirements for use in GMP-compliant QC laboratories performing release testing of petroleum products.
How is temperature uniformity verified across multiple test positions?
Uniformity is confirmed during factory acceptance testing using nine-point NIST-traceable probe mapping at 50 °C, 100 °C, and 150 °C; a certificate of uniformity is supplied with each unit.
Does the instrument include test strips or sample holders?
No—copper and silver test strips, polishing kits, and glass test tubes are supplied separately as consumables; standardized rack inserts for 9-position configuration are included.
