Holiday Testing

What is Holiday Testing? 

Holiday Testing is a non-destructive testing (NDT) method used to detect discontinuities, such as pinholes, voids, and thin spots, in protective coatings applied to metal surfaces. These imperfections, known as "holidays," can compromise the coating's integrity, leading to corrosion, contamination, and premature failure of the underlying material. 

Industries such as oil and gas, marine, and infrastructure rely on Holiday Testing to ensure protective coatings meet quality standards, safeguarding critical assets against environmental degradation. Dexon Technology’s advanced Holiday Testing solutions help operators maintain compliance with industry regulations and enhance the longevity of their infrastructure. 

Common Problems and How Holiday Testing Provides Solutions 

Coating defects can lead to serious structural and operational challenges, including: 

• Corrosion and Material Degradation: Undetected holidays expose the substrate to moisture, chemicals, and environmental factors, accelerating deterioration. 

• Reduced Service Life: Compromised coatings lead to premature failure, increasing maintenance costs and downtime. 

• Quality Control Issues: Inconsistent coating application results in non-compliance with industry regulations and performance expectations. 

Holiday Testing addresses these challenges by: 

• Detecting Coating Defects Early: Identifying pinholes, cracks, and other imperfections before the asset is placed into service. 

• Ensuring Coating Integrity: Verifying that coatings provide the intended level of protection against corrosion and external elements. 

• Enhancing Regulatory Compliance: Meeting industry standards such as NACE, ASTM, and ISO specifications for protective coatings. 

• Preventing Costly Repairs: Early detection of coating flaws minimizes future repair expenses and operational risks. 

By incorporating Holiday Testing into quality control and maintenance programs, Dexon Technology helps clients protect their assets, reduce operational costs, and ensure long-term reliability. 

Methods Used in Dexon’s Holiday Testing Services 

Dexon Technology employs advanced testing techniques to ensure thorough and accurate coating evaluations, including: 

• Low-Voltage Wet Sponge Testing: Ideal for detecting holidays in thin coatings (<500 microns) on conductive substrates using a moistened sponge and electrical current. 

• High-Voltage Spark Testing: Used for thicker coatings, this method applies a high-voltage probe to identify discontinuities through dielectric breakdown. 

• Automated Inspection Solutions: Advanced inspection systems integrate with data logging to ensure comprehensive defect analysis and reporting.
