Custom Sprinkler Testing

Interested in knowing at what temperature a head goes off?  While the sensitivity and functionality testing required for periodical testing per NFPA 25 Section 5.3 should involve the RTI plunge test, the sprinkler testing equipment at Dyne also has the capability to tell you at what temperature a head will activate.  Where the RTI plunge test involves plunging a sprinkler head into a specified temperature and determining how long it takes to go off, this custom work would involve increasing the temperature in the sprinkler oven over time until it is hot enough to activate the head.  A report would be issued with the response temperature instead of response time.  This would be great for research into sprinkler performance issues unrelated to periodical testing.  For this custom sprinkler testing, the parameters of the test would be specified by the customer (rate of temperature rise, dwell time between temperature increases, start and end points, etc.) and then programmed into our equipment. Please note that the testing parameters can greatly increase the amount of time required.  Since some testing parameters may require a considerable amount of time, turnaround time may vary.  Contact a technician at Dyne for more information at 800-632-2304 or

Dyne Technologies will no longer be identifying recalled heads on the response time report going forward - March 2017

Dyne Technologies will no longer be identifying recalled heads on the response time report for sprinklers going forward.  All heads received will be put through the testing process and will receive a response time result.

This decision was made in response to the lack of a centralized, readily available list of recalled heads.  Dyne Technologies has discussed the topic of recalled heads with a variety of manufacturers who confirm there is no centralized list of all recalled heads but also stress they are up front with customers about recalls and take a proactive approach to them.  Furthermore, there are voluntary recalls and requests for replacement made by the authority having jurisdiction without a manufacturer’s recall that make it difficult to know in which circumstances replacement is actually required.

According to NFPA 25 4.1.5, it is the responsibility of the property owner or designated representative to correct or repair deficiencies or impairments.  This includes identifying and replacing or remedying any recalled products.  Please consult the manufacturer of any heads you feel may be recalled.

As always, Dyne Technologies is available to assist with any questions about sprinkler head testing as well as help customers get the information they need to understand the issue of recalled sprinkler heads.  Contact us today if you have questions or need test kits sent out.

Dyne Technologies is excited to announce that we now offer Sprinkler Head Testing

We are excited to announce that we have expanded our testing lab services to include Sprinkler Head Testing beginning in December 2016. Our state-of-the-art sprinkler test tunnel will be used to ensure that sprinkler heads are in compliance.

The National Fire Protection Association (NFPA) Standard for Inspecting, Testing and Maintenance of Water-Based Fire Protection Systems, NFPA 25, requires building owners to have a sample of their installed sprinklers periodically tested by a recognized testing laboratory.  NFPA states “a representative sample of the sprinklers in a system should consist of a minimum of 4 sprinklers or 1% of the number of sprinklers per individual sample, whichever is greater.”

Our independent laboratory services customers throughout the world.  Dyne’s primary business has been testing firefighting foam and antifreeze solution but will now also include testing sprinkler heads.  Using a state-of-the-art sprinkler test tunnel, Dyne will test the sprinklers’ thermal sensitivity and make sure the waterway is properly functioning according to the standards.   We pride ourselves on “Quick, Easy, Accurate and Independent Testing”,  says Mark Spaniol, President of Dyne Technologies.  “Accuracy and being Independent is a cornerstone of our lab, we are ISO 9001 certified and take pride in the quality of our test results.  Our customers demand and deserve a quick and easy testing process and this is why we offer free test kits with free shipping and five day turnaround on testing results.” 

We perform a visual inspection in addition to subjecting the sprinkler head to a plunge oven test to determine the release time. This test is designed to ensure the sprinkler head will release in a specified time when exposed to a specified temperature. As required by Underwriters Laboratory 199, International Standards Organization  6182-1, and Factory Mutual Class Number 2000, the Response Time Index (RTI) value (meter/second)1/2 between 80 and 350 is required for a standard sprinkler while a maximum value of 50 is required for a quick response head.

Dyne Technologies was founded in 1999 by Joan Leedy, who is the Technical Director at Dyne Technologies.  She explains, ”Our number one goal is accurate test results to ensure that our customers’ fire protection products are performing as designed. This holds true for firefighting foam, antifreeze solutions and sprinklers.”

Why Foam Fails

The National Fire Protection Association Standard on Foam - NFPA 11 - recommends foam concentrate be tested at least annually. There are several reasons why fire-fighting foam may fail NFPA 11 testing. Understanding the reasons a foam may fail can help you to prevent these failures and ensure your system will work properly in an emergency.

Dilution with water is the most common reason why fire-fighting foam fails. If the tank is not properly isolated, water can inadvertently get into a tank and dilute the foam concentrate. A properly designed system has isolation valves and backflow prevention valves to prevent inadvertent dilution. When fire-fighting foam becomes diluted, it will not work effectively in the event of a fire.
