Smoke & Toxicity Testing

SwRI performs the ISO 5659 test to determine industry compliance to fire risk and hazard criteria of accumulated products of combustion (smoke density, off-gassing and toxicity elements).


We offer smoke and toxicity tests in accordance with a variety of standard procedures. Standard tests and customized tests are available to help our clients meet their needs.

For questions about this testing, please contact Karen Carpenter at +1 210 522 3718.

Experimental support is provided to the Listing, Labeling and Follow-Up Inspection Services Section in the form of testing services for quality assurance of products and materials. Qualification and verification testing is provided in support of third party quality assurance programs.
