Q. How do I take a sample?

A. Proper sampling of foam is very important, see the article Tips on Proper Sampling for more information. We also have a video on how to prepare your samples to send to us for testing.

Q. What is Proportioning Testing?

A. Verifying that a firefighting foam system accurately proportions foam and water is critical to the system’s effectiveness in the event of a fire. Our Proportioning Testing article explains why you should consider proportioning testing.  A proportioning sample requires a sample of concentrate as well as the proportioned sample. You may send sample of system water.

Q. How often are we required to test our foam?

 A. NFPA 11 2016 Edition Section 12.6. states At least annually an inspection shall be made of foam concentrates and their tanks or storage for evidence of excessive sludging or deterioration. Samples of concentrates shall be sent to the manufacturer or qualified laboratory for quality condition testing. For more NFPA information, visit

Q. How much sample (ml or ounces) is required for testing?

A. We require at least 8 ounces or 250 ml for NFPA testing. For IMO/USCG testing, we offer 500 ml kits (see IMO/USCG below).

Q. Should I also test the bladder water?

A. The National Fire Protection Association Standard 25, Inspection, Testing and Maintenance of Water-Based Fire Protection Systems recommends foam bladder tanks systems be inspected at least annually.  Click on the following link to read more about Bladder Water Testing.

Q. Should I take a top and a bottom sample?

A. If the sample being taken is a foam concentrate sample, keep in mind that these tanks contain a large volume of foam that may not be uniform throughout. The tank should be sampled from two different areas, the top and the bottom for example, to help ensure that the foam is acceptable throughout. Click on the following link to read Tips on Proper Sampling.

Q. What type of tests are performed on a standard foam concentrate?

A. Go to the Foam Testing Explanation article for information on performance and physical tests performed on foam at Dyne.

Q. What is the best way to package and return the full sample bottles in the kit box?

A. View the video: Preparing Your Foam Samples for Dyne. Please fill the sample bottles to the fill line. Be sure to tighten the caps securely as they can loosen in transit. Tape the caps shut (electrical tape works great). Place the full bottles in the plastic bag and seal the bag. Make sure to include the return form outside of the plastic bag and remember to include a PO or credit card (do not send a check). If you tape the outside of the box shut, that helps too.

Remember to return the kits using the enclosed UPS return label or via the U.S. postal service. If you use the UPS label, be sure to keep the tracking number in order to be able to follow the package to Dyne. UPS Ground generally takes 3-5 days within the U.S.

Q. What do I do if my foam sample fails? Can I talk to someone at Dyne?

A. Call Dyne at 800-632-2304 to discuss your test results with a chemist. We also have a video and published an article on Why Firefighting Foam Fails.

Q. I have some bottles, what can I fill out and return with my samples?

A. Click here to download the foam sample return form.

Q. Who can I contact for maintenance on the tank or new foam?

A. View our list of foam manufacturers.

Q. What temperature range should the foam be stored?

A. For the purposes of test uniformity, a liquid concentrate is to be categorized according to the minimum storage temperature at which it may be inducted or proportioned in acceptable concentrations. Minimum storage temperatures are to be minus 20°F (minus 28.9°C), 0°F (minus 17.8°C), 20°F (minus 6.7°C), or 35°F (1.7°C).

UL Statement: Liquid concentrates may be stored in the original shipping containers or in pressure-proportioning tanks. Liquid concentrates are not intended to be stored at temperatures lower than those for which they have been certified or above 120°F. They should be stored in locations free of excessive moisture to avoid external corrosion of containers and other equipment. For more specific information, reference the foam manufacturer.

Q. I see IMO/USCG on the return form. What is IMO/USCG testing?

A. Filling out the paperwork for a sample of firefighting foam to send into Dyne for testing can be confusing if you are unfamiliar with some of the language or testing methods used in the firefighting foam business. IMO and NFPA have similar standards for firefighting foam testing except IMO stipulates a slightly more rigorous analysis. IMO stands for International Maritime Organization and USCG is the United States Coast Guard. Factors to consider when making this decision are detailed in the article NFPA or IMO Foam Testing – Which is Right for You.

Q. How many bottles are in each IMO/USCG foam test kit?

A. We offer a 1-500 ml bottle kit as well as a 2-500 ml bottle kit for IMO/USCG testing. Please order the kit that best suits your needs to save on shipping costs.

Q. Have sprinklers ever been recalled?

A. The largest recall occurred back in 2001 and it involved a large number of sprinklers utilizing o-ring seals. Many of the manufacturers of these recalled sprinklers offered a free replacement but only for a specific time period which has since expired. If a recalled sprinkler is sent to Dyne for testing, the sprinkler will be put through the testing process and will receive a response time result.

It is the responsibility of the property owner or designated representative to correct deficiencies or impairments according to NFPA 25 4.1.5. This includes identifying and replacing or remedying any recalled products. Dyne Technologies does not identify recalled products or ensure required action is taken.
