Chemical Resistance Testing For Cleanroom Flooring

cleanroom flooring

Typically used for scientific research or in laboratory environments, a cleanroom is a highly controlled environment. From pollutants to chemicals, static to microbes, every last detail matters in achieving optimal results. Because of the level of regulation, elements like cleanroom flooring also need to meet specific requirements. One of those requirements relates to the amount of chemical resistance the flooring provides.

While there are methods of testing available, there is often confusion around the tests for several reasons. In this article, we’re looking at some of the factors you should understand when considering chemical resistance for your cleanroom flooring.



The ASTM F925 is a standard testing method for common chemicals. This test provides a method for determining the resistance of flooring materials to surface deterioration when it’s exposed to those chemicals. However, this test method is reliable only for the specific chemicals listed.


SEFA Testing

On the other hand, SEFA has created a much more rigorous list of chemicals. This list is not only broader but more aggressive in the chemicals tested. However, it’s important to remember that passing this test is not the goal. Instead, SEFA testing shows that a particular product has been tested, what it is suitable for, and what it is not. Rated on good, better, and best levels, the results are fairly simple to translate.

Beyond the good, better, and best, consumers will also find ratings on effectiveness. Although the SEFA list is comprehensive, it is not 100% inclusive. For example, several labs contain other materials that aren’t included on the list. If this situation applies to you, it’s best to conduct your own testing against chemical resistance.


Individual Testing

While testing results are an excellent source of reference, sometimes, it’s best to testing on your own. At SelecTech, we’re happy to send cleanroom flooring samples that enable you to undergo this process. The benefit is a hands-on experiment, under your full control to obtain accurate results for the chemicals used within your facility.

When testing, there is no right or wrong method. Applying the chemical in question to the sample flooring will provide you with the answer you’re looking for. However, this may mean allowing the chemical to penetrate the flooring for five minutes or five days – the period of time is up to you.
