FAQs (UV Test Chamber Condensation Cycle Testing)

Q1: How does UV exposure affect adhesive bond strength?
A: UV radiation degrades polymer chains, causing brittleness and bond failure; this equipment quantifies such effects under controlled conditions.

Q2: Can it test UV-curable adhesives?
A: Yescustom profiles simulate curing and post-cure UV exposure for hybrid adhesives.

Q3: What is the typical test duration?
A: Tests range from 48500 hours, depending on adhesive type and irradiance settings.

Q4: How to maintain load cell accuracy?
A: Calibrate quarterly using NIST-traceable weights; avoid overloading beyond 80% capacity.

Q5: Does it comply with BIS standards?
A: Yespre-set profiles align with IS 16046 for industrial adhesives.
