Overview
The TQC Surface Preparation Test Kit is a field-deployable, integrated solution engineered for quantitative and qualitative assessment of surface contamination prior to protective coating application—particularly on carbon steel substrates in marine, infrastructure, and industrial maintenance environments. Designed in accordance with ISO 8502-6 (soluble salt testing), ISO 8502-9 (dust rating), and SSPC-SP 13/NACE No. 6 standards, this kit enables inspectors and coating applicators to verify compliance with surface cleanliness requirements before primer or topcoat application. The system operates on established physical and electrochemical principles: conductivity-based measurement of chloride, sulfate, and nitrate ions extracted from surfaces using Bresle patches; visual particle counting and classification per ISO 8502-3; and optical magnification-assisted evaluation of residual contaminants and substrate profile integrity.
Key Features
- Modular, ruggedized carry case constructed from impact-resistant polypropylene with custom-cut foam inserts—designed for repeated field transport and on-site deployment without equipment misplacement or damage.
- Integrated Bresle test module compliant with ISO 8502-6: includes calibrated Bresle pouches, precision syringes (10 mL), conductivity meter with temperature compensation, and certified calibration standards traceable to NIST.
- Dust test kit conforming to ISO 8502-3 and ISO 8502-9: contains graded adhesive tapes, standardized comparison charts (ISO 8502-9 Dust Rating Scale), and a portable LED-lit viewing stand for consistent illumination during particle assessment.
- Portable 10×–40× zoom stereo microscope with adjustable LED ring light, enabling real-time inspection of surface profile, mill scale remnants, rust morphology, and embedded particulates post-blast or pre-wash.
- All instruments calibrated and supplied with individual calibration certificates; traceability documentation provided for audit readiness under ISO/IEC 17025-accredited quality systems.
Sample Compatibility & Compliance
The kit is validated for use on blast-cleaned, water-rinsed, and solvent-wiped ferrous substrates—including structural steel, pipelines, ship hulls, and storage tanks. It supports extraction media compatibility with deionized water (for Bresle testing) and is compatible with standard ISO 8502-compliant test solutions. All components meet RoHS Directive 2011/65/EU requirements. The conductivity meter complies with IEC 61000-4-3 (EMC immunity) and IP65 ingress protection rating for field durability. Documentation supports GLP-aligned recordkeeping and is structured to facilitate integration into client-specific QA/QC workflows aligned with ISO 9001, ISO 14001, and OHSAS 18001 frameworks.
Software & Data Management
While the core kit operates as a manual, instrument-based system, optional digital reporting modules are available via TQC’s CloudLink™ platform (sold separately). This web-based interface enables users to log test location (GPS-tagged), operator ID, substrate type, environmental conditions (RH, ambient temperature), and raw measurement data—including conductivity values converted to NaCl-equivalent (mg/m²) per ISO 8502-6 Annex B. Audit trails are time-stamped and user-locked; export formats include PDF reports compliant with ASTM D3359 and SSPC VIS 1–4 documentation standards. Full Part 11 compliance—including electronic signatures, audit trail review, and role-based access control—is available when deployed on validated enterprise servers.
Applications
- Pre-coating verification on offshore platforms and FPSOs where soluble salt contamination directly correlates with premature coating failure and underfilm corrosion.
- Third-party inspection during refinery turnaround projects requiring adherence to API RP 571 and NACE SP0188 guidelines.
- QA/QC monitoring in bridge rehabilitation programs governed by AASHTO M280 and EN ISO 12944-4.
- In-house training labs for NACE Level 1/2 and SSPC C3-certified personnel seeking hands-on competency development in surface preparation validation.
- Root cause analysis of coating adhesion failures through retrospective dust and salt residue correlation with blistering or cathodic disbondment patterns.
FAQ
Does the kit include calibration certificates for all instruments?
Yes—each conductivity meter, syringe, and reference standard is supplied with an individual calibration certificate indicating date, method, uncertainty, and traceability to national metrology institutes.
Can the Bresle test be performed on curved or welded surfaces?
Yes—the flexible Bresle pouch design and low-profile sealing gel allow reliable application on radiused surfaces, weld caps, and flange edges per ISO 8502-6 Clause 6.2.
Is training provided with purchase?
TQC offers optional on-site or virtual instructor-led training accredited by NACE International, covering ISO 8502 interpretation, measurement uncertainty estimation, and report generation per client QA protocols.
What consumables require periodic replenishment?
Bresle pouches, adhesive dust tapes, calibration standards, and replacement microscope bulbs are consumables with typical shelf life and usage intervals documented in the included Operator Manual.
Is the kit suitable for use in explosive atmospheres (ATEX zones)?
No—none of the included electronic instruments are ATEX-certified; however, non-powered components (tapes, pouches, microscope) may be used in Zone 2 areas under strict site safety supervision and lockout procedures.
