Manufactured by our TQC Sheen paint testing specialist brand, the Bresle Test Kit (SP7310) is a portable field kit for detecting soluble salt contamination on blast-cleaned steel surfaces prior to coating application. Salt trapped under a coating attracts moisture through its hygroscopic nature – causing corrosion, pitting and coating failure – and cannot be seen by the naked eye. The Bresle Method (ISO 8502-6, ISO 8502-9) is the international standard technique for measuring this contamination in milligrams per square meter.
Used by marine coating surveyors, offshore and pipeline coating inspectors, shipyard coating QC teams, protective coating applicators in oil and gas, and blast-cleaning contractors doing pre-coating surface verification – the Bresle Test Kit supports Corrosion Testing and pre-coating Coating Testing applications where blast-cleaned surfaces may look clean but carry chloride, sulfate or nitrate contamination from air pollution, maritime environment exposure, or contaminated blast media.
Complete kit contents include a digital conductivity meter (IP67-rated for field use, 0.1 to 20,000 mg/m² range with DSP Direct Sample Procedure method), 25 Bresle patches with latex membrane (12.5 cm² test area, 2.5 ml volume), deionized water, calibration and rinse solution, cups and syringes – all inside a rugged carrying case. The same kit supports both pre-coating surface QC and blast-media contamination testing, so incoming abrasive QC and in-process surface verification run from a single tool. Across the Industrial Physics portfolio we make a wide range of Bresle kit related products, including replacement patches, calibration solutions, and deionized water bottles.
Defensible pre-coating salt contamination data to ISO 8502-6 and ISO 8502-9. Complies with ISO 8502-6 (Bresle method extraction) and ISO 8502-9 (conductometric determination) – so pre-coating surface QC stands up under coating manufacturer warranty audit, pipeline project QC reporting, and marine/offshore protective coating specification compliance.
DSP method support, IP67 digital meter, field-ready. Direct Sample Procedure (DSP) method delivers faster and more accurate results than legacy patch-and-syringe workflows. The digital conductivity meter is IP67-rated with 1% accuracy, 0.1 mg/m² resolution, Automatic Temperature Compensation across 0-50°C, and auto-off after 8.5 minutes – built for shipyard, offshore and site inspection conditions.
Complete kit ready to go, blast-media testing capability included. One kit supports two workflows: surface contamination assessment BEFORE coating (via ISO 8502-6/9) AND blast media contamination testing (via ISO 11127-6) – so incoming abrasive QC and in-process surface verification run from a single tool without swapping instruments.
The TQC Sheen Bresle Test Kit is designed to support soluble salt contamination testing to the following international standards:
The same Bresle Test Kit supports blast-media contamination testing alongside pre-coating surface QC. This second workflow is critical because dissolved salts in recycled abrasive media or blast water can re-contaminate the surface being cleaned – defeating the surface preparation effort. Regular blast-media conductivity checks per ISO 11127-6 catch contamination early, before it reaches the substrate. Same instrument, same protocol – no additional purchase needed to add blast-media QC to the workflow.
For ongoing Bresle testing, the primary consumable is TQC Sheen Bresle Patches (LD6515, box of 25). Deionized water is available in 200ml and 500ml bottles for replenishment. Meter calibration uses the TQC Sheen Conductivity 84 µS/cm Calibration Solution. Spare Bresle Test Syringe and Needle and Plastic Cups for Bresle Test Kit are stocked for the wear-and-tear parts of the kit.
For adjacent pre-coating surface preparation workflows, consider the TQC Sheen Pre-treatment Test Kit (PTK) (broader pre-treatment verification) and the TQC Sheen Elite Multifunctional Meter (companion instrument for conductivity, TDS, salinity and temperature).

When you enquire about the TQC Sheen Bresle Test Kit, our TQC Sheen specialists will confirm your typical inspection environment (shipyard, offshore, pipeline, industrial coating site), whether you need blast-media testing alongside surface QC, your reporting convention for conductivity (sodium chloride, mixed salts, or chlorides only), and ongoing consumable requirements (Bresle patches, deionized water) for your inspection volume.
For purchasing teams, we provide the SKU (SP7310), dispatch confirmation within 2 days from stock, and quotation turnaround for the complete kit plus standing consumable orders. Volume pricing on Bresle patches and deionized water available for high-frequency inspection operations.
Every TQC Sheen Bresle Test Kit is supplied with a 1 year parts and labour warranty as standard – our Industrial Physics group commitment across all brands. Because the Bresle Test Kit is a consumable-driven field instrument, ongoing support focuses on replenishment of Bresle Patches (single-use, box of 25), deionized water (in 200ml or 500ml bottles), and periodic recalibration of the digital conductivity meter using TQC Sheen Conductivity 84 µS/cm Calibration Solution. To arrange service, calibration verification or spares, contact our support team.
Beyond the warranty period, the Industrial Physics global service network provides advice on Bresle protocol interpretation across ISO 8502-6 and 8502-9, DSP method training and cross-verification, and integrating the Bresle Test Kit into a documented QMS workflow across coating projects, drydocks and pipeline construction sites.

The Bresle Method is the international standard technique for measuring soluble salt contamination on blast-cleaned steel surfaces before coating application, described in ISO 8502-6 and ISO 8502-9. A self-adhesive latex patch is applied to the surface, filled with deionized water via a syringe, worked through the patch to dissolve any surface salts, then extracted and measured for conductivity. The TQC Sheen Bresle Test Kit (SP7310) provides everything needed to run the test – digital conductivity meter, 25 Bresle patches, 6 x 25ml beakers, 200ml distilled water, 20ml syringe with needle, calibration and rinse solution, and a magnetic Bresle test spot marker. The meter reads the combined conductivity of dissolved chlorides, sulphates and nitrates.
The kit complies with ISO 8502-6 (extraction of soluble contaminants for analysis – the Bresle method), ISO 8502-9 (field method for the conductometric determination of water-soluble salts), and ISO 11127-6 (methods for testing of non-metallic blast-cleaning abrasives – water-soluble contaminants). Together these cover both the surface contamination assessment before coating and the contamination check on blast media in use – so the same kit supports incoming abrasive QC, in-process blast-media checks and pre-coating surface verification.
The digital conductivity meter supplied with the Bresle Test Kit covers 0.1 to 20,000 mg/m² using the DSP (Direct Sample Procedure) method, with 0.1 mg/m² resolution and 1% full-scale accuracy. Operating temperature range is 0 to 50°C with a normalization temperature of 25°C. The meter is IP67-rated for field use. Each Bresle patch has a test area of 12.5 cm² (1,250 mm²) with a 2.5 ml nominal volume. Consult the appropriate standard (ISO 8502-6 or -9) for correct test execution and result interpretation – the meter reports conductivity which is then converted to salt concentration based on the reporting convention you use (measured as sodium chloride, mixed salts, or chlorides only).
Three practical points make or break Bresle results: use only the supplied deionized water (or TQC Sheen replacement 200ml or 500ml bottles) – tap or distilled water skews readings; work the syringe through the patch enough times to fully dissolve surface salts (typical practice is at least 4 fill-and-extract cycles); and record whether you are reporting conductivity as sodium chloride, mixed salts, or chlorides only, since the calculation factors differ. Our knowledge base article on the Bresle method Direct Sample Procedure (DSP) covers newer techniques the SP7310 kit supports.
The three consumables that get used up in routine Bresle testing are the Bresle Patches (LD6515, box of 25 – each patch is single-use), the deionized water (200ml or 500ml replacement bottles), and periodically the calibration solution for the conductivity meter. Order frequency depends on your test volume – a QC team running 10-20 tests per week typically reorders patches monthly and deionized water bi-monthly. Contact our support team for volume pricing or to bundle a starter consumables pack with the kit.
