SAMPLES NEEDED
Two 12"x12" pieces of each surface type
TYPICAL TURNAROUND
2-4 day turnaround
You probably need this if
You manufacture or fabricate lab countertops or sinks and need SEFA 3 test results
You’re launching a new surface material or color
What the test involves
01
Chemical exposure
Surface samples are exposed for 24 hours to 49 reagents, including acids, bases, solvents and salts. Volatile chemicals are held against the surface under an inverted container, and the rest are applied as drops under a watch glass
02
Cleaning and rating
Each spot is cleaned and rated from 0 (no effect) to 3 (an objectionable change in appearance)
03
Reporting
Results are documented on the SEFA 3 test submittal form
Common questions
What is SEFA 3?
It’s the laboratory work surfaces standard published by the Scientific Equipment and Furniture Association. It sets the performance criteria for lab countertops and sinks, with chemical and stain resistance as the central test.
What does it take to pass SEFA 3?
Each of the 49 chemical spots is rated from 0 to 3. A laboratory grade work surface can have no more than four ratings of 3.
Does SEFA 3 testing have to be done by an approved lab?
Yes. The standard requires testing to be performed and documented by a SEFA-approved third-party lab. Gaynes Labs is on SEFA’s approved list for SEFA 3, 7, 8 and 10.
Not certain SEFA 3 is the right test?
