BQCIS

Assessing Coating Performance and Corrosion Resistance

Salt spray testing is a widely recognized accelerated corrosion method used to evaluate protective coatings and metallic substrates. At BQCIS, we operate calibrated salt fog chambers performing continuous and cyclic corrosion exposures under international standards such as ASTM B117, ISO 9227, IEC 60068-2-11, and OEM-specific test methods.

Our laboratory simulates long-term environmental exposure including salt fog, humidity, and drying cycles to reveal coating performance, paint adhesion, blistering, rust formation, and corrosion propagation. Results guide manufacturers in quality assurance, product validation, and material selection.

Whether for automotive, aerospace, construction, or marine components, BQCIS provides repeatable and traceable test data that meet the most demanding durability requirements.

Key Activities in Salt Spray & Corrosion Testing

Salt Fog Chamber Exposure

Execution of neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-accelerated acetic acid salt spray (CASS) tests.

Cyclic Corrosion Testing (CCT)

Alternating wet/dry, humidity, and salt fog cycles replicating real-world atmospheric conditions.

Surface Preparation & Masking

Specimen cleaning, panel cutting, scribing, and controlled masking to meet standard sample prep requirements.

Visual & Microscopic Evaluation

Assessment of rust grade, blistering, delamination, and corrosion creep using ISO 4628 and ASTM D610/D714 methods.

Mass Loss Measurement

Quantification of metal weight loss to evaluate corrosion rates and coating protection efficiency.

Adhesion & Coating Integrity

Cross-hatch, pull-off, and bend tests to assess coating adhesion before and after corrosion exposure.

Failure Mapping & Reporting

Detailed failure documentation, macro/micro photography, and compliance certificates with traceability.

Comparative Benchmarking

Side-by-side testing of material batches or supplier products to validate consistency and performance.

Certification Support

Providing accredited test reports to support product qualification for marine, automotive, and industrial standards.

Success Story

Corrosion Resistance Validation for Automotive Components

The Challenge:

An automotive OEM required verification of zinc-nickel coated fasteners to ensure 720-hour corrosion protection under NSS and CCT conditions.

Our Solution:

BQCIS performed cyclic corrosion exposure (VDA 233-102) combined with adhesion and scribe creep testing, providing digital photo records and ISO 9227-compliant data logs.

The Result:

All fasteners exceeded 1000-hour resistance with no red rust formation. OEM granted final supplier approval and process qualification.
