idjárásteszt

Idjárásteszt is a Hungarian term describing testing procedures that simulate weather conditions to assess the performance, reliability, and durability of products, components, or systems. The term is formed from időjárás, meaning weather, and teszt, meaning test. In practice, idjárásteszt encompasses a range of environmental tests that expose samples to controlled combinations of temperature, humidity, wind, rain, UV radiation, and other atmospheric factors in order to predict real‑world behavior.

Applications include consumer electronics subjected to temperature cycling and humidity, automotive and aerospace components tested for climate and moisture resistance, outdoor equipment and building materials evaluated for weathering and corrosion, and software or simulation tools that model or respond to weather data. Tests are typically conducted in climatic chambers, rain simulators, wind tunnels, UV cabinets, or salt spray rigs, often with accelerated profiles to simulate long-term exposure within a shorter period. Protocols may follow international standards for environmental testing, which prescribe test conditions, durations, measurement methods, and acceptance criteria.

Results of idjárásteszt inform design changes, material selection, protective coatings, product warranties, and marketing claims. While useful, such tests are simplifications of complex field conditions and may not capture all variations of real weather; they are usually complemented by field testing and lifecycle analyses.
