Industry Applications

Medical Devices & Healthcare
We use controlled temperature and humidity chambers to perform environmental preconditioning before transit testing.

Pharmaceuticals & Biotech
We conduct cold chain thermal qualification and distribution simulation for temperature-sensitive drugs and biologics. Our chambers simulate frozen, refrigerated, humid, dry, and hot profiles per ASTM D4332, ASTM D3103, ASTM D7386, ISTA 7D, and ISTA 7E.

Consumer Products & Retail
We test individual packages and pallets for retail distribution centers and direct-to-consumer shipments. Environmental conditioning follows ISTA 3A, ISTA 3E, ISTA-6 (Amazon, Sam's Club, FedEx), ASTM D4169, ASTM D4332, and ASTM D7386.

Food & Beverage
We perform humidity and temperature simulation for packaging integrity and shelf-life validation, plus cold chain qualification for perishables per ISTA 7D, ISTA 7E, ASTM D4169, ISTA 3A, ISTA 3E, and ASTM D4332.

Automotive
We test automotive components, coatings, and packaging for corrosion resistance, thermal cycling, and humidity exposure.

Aerospace
We perform altitude simulation, salt fog corrosion, humidity exposure, thermal cycling, and flammability testing for aerospace components, subsystems, and packaging.

Industrial & Heavy Equipment
We run long-duration environmental exposure testing for seals, protective coatings, and industrial packaging per ASTM D4332, ASTM D4169, and ASTM B117, including salt fog, humidity cycling, and temperature extremes.

Electronics
We test assembled electronics, subcomponents, and packaging under temperature, humidity, thermal shock, and vibration conditions.

Frequently asked questions

What is environmental testing and why is it required?

Environmental testing evaluates how products, materials, and packaging perform when exposed to controlled temperature, humidity, altitude, corrosion, and other conditions that simulate real-world shipping, storage, and use. Regulatory and industry governing bodies often require environmental testing as part of formal packaging and product validation programs. Environmental testing is typically performed before a product or packaging design is approved for distribution and again whenever materials, suppliers, or packaging designs change.

What is conditioning and why does it happen before distribution testing?

Environmental conditioning is the process of exposing a package or product to controlled temperature and humidity profiles for a period of time before mechanical distribution testing is performed. It is required because packaging materials like corrugated board, foam, adhesives, and polymers change their physical properties when exposed to heat, cold, or moisture.

Testing a package that has not been conditioned produces results that may not reflect real-world performance, which can lead to packaging failures in the field and regulatory problems during audits.

Gaynes Labs performs environmental conditioning using controlled temperature and humidity chambers, walk-in environmental chambers, and altitude simulation equipment.
