Humidity and water resistance testing involves subjecting materials and components with or without coatings to water vapor or liquid water at various temperatures, thus simulating structure and equipment operating under different climatic conditions ranging from dry arctic climate to warm and humid tropical and subtropical climate. Hydration is one of the most basic forms of corrosion in addition to oxidation. Hydration generally leads to reduction in mechanical and chemical integrity of structure and equipment. Many materials suffer from this. Some simple examples of materials that suffer from humidity and water are concrete, polymers, polymer composites, organic coatings on metals, etc.
Capability – At TTL, we have humidity chambers to test small sample to full size components. We run tests routinely for polymer and composite manufacturers, as well as coatings developers.
Some relevant standards:
Corrosion resistance testing assess the impact of corrosive atmospheres on components, coatings, etc. Atmospheres are in general classified in to reductive, neutral, and oxidative atmosphere. Normal air which contains oxygen can be considered oxidative. Thus, some materials like iron will continue to rust and become oxidized if exposed to normal air for long period of… Continue Reading
Product testing generally refers to testing finished products before being shipped to customer or consumer. It differs from material testing in that an additional aspect of product geometry, product surface, etc., their influence on the product performance is tested. Some well-known examples of product testing are automotive crash testing to assess crash worthiness of the… Continue Reading
Touchstone is committed to providing its customers with quality, reliable test results. That is why we have undertaken the rigorous steps needed to meet and secure the most stringent of test lab accreditations including ISO/IEC 17025, NADCAP 7101 (Materials Test Lab) and NADCAP 7122-I (Non-Metallics Materials Testing).
