That hazy film on the inside of a car windscreen? It comes from volatile compounds evaporating out of interior plastics, foams, and trims — and OEMs set strict limits on it. Choosing the right lab to measure it matters. If you’re looking for the top fogging resistance testing service in chennai, this guide shows what to look for and how Kiyo R&D Lab delivers accurate, standard-based fogging results you can put in front of any automotive customer.
From dashboards and door trims to foams, adhesives, and textiles, our expert team delivers reliable fogging data, supporting analysis, and clear, audit-ready reports you can rely on.
Fogging is the condensable film that forms when volatile substances evaporate from interior materials and settle on cooler surfaces like glass. Fogging resistance testing heats a sample in a controlled vessel, collects what evaporates on a cold plate or foil, and measures it — either as loss of gloss (reflectometric) or as condensed weight (gravimetric). The top fogging resistance testing service in chennai gives you numbers that match OEM limits exactly, so your parts pass first time.
For automotive suppliers, it’s a mandatory acceptance test. For material developers, it guides low-emission formulations. For QC, it confirms each batch still meets spec — all backed by recognised methods.
Not every lab reports fogging the way your OEM expects. To pick the top fogging resistance testing service in chennai, weigh these six factors before you send samples.
