Why Sprinkler Testing Compliance Matters

Fire sprinkler performance can change over time in ways that are not always visible during inspections. Corrosion, obstructions, coating degradation, loading, and other age-related conditions may affect sprinkler operation.

NFPA 25 requires periodic sprinkler testing to verify continued performance against established acceptance criteria. Test results help support maintenance decisions, identify potential deficiencies, and demonstrate compliance with inspection, testing, and maintenance requirements.

Fire Sprinkler Testing Overview

NFPA 25 requires building owners to have a sample of the installed sprinklers tested by an approved testing lab. Dyne tests the response time of the sprinklers to confirm they will release in a specified amount of time when exposed to a defined temperature and air flow. The acceptable response time is based on a response time index (RTI). The RTI requirements are listed below. Note that a sprinkler coated with a material for corrosion resistance (wax for example) is allowed extra time as defined in UL 199. The response time of the coated standard response sprinkler is 180 seconds or the maximum response time (whichever is greater).

Sprinkler Definitions:

ESFR RTI value should not exceed 50 (meters-seconds)^1/2

Fast Response RTI value should not exceed 65 (meters-seconds)^1/2

Standard Response RTI value should not exceed 350 (meters-seconds)^1/2

If the response time does not meet the RTI requirement, the sprinkler response time will be marked as “FAIL”. Failure to meet the RTI requirement may result from, but is not limited to, the following:

Loading
Corrosion
Paint (other than that applied by manufacture)
Missing fluid in glass bulb (if applicable)

Additionally, if the release mechanism does not activate, the water seal does not release, pressure loss is not detected due to a blocked waterway, or the water seal remains partially attached, the sprinkler will be marked as “FAIL” on the report. If a sprinkler fails to meet the requirements as defined above, all sprinklers within the area represented by the failure shall be replaced per NFPA 25 2026 Ed. Section 5.3.1.3.

Key Capabilities Include:

Evaluation of sprinkler thermal sensitivity andfunctionality as established by NFPA 25, helping owners determine whethersprinklers can remain in service or require replacement.
Identification of degradation detrimental to sprinkler performance that may not be visible during routine visual inspections.
Images of the sprinkler pre- and post-testing that can be used to help identify any obstructions that may still impede functionality.
Actionable test reports that provide clear results and recommendations, helping system owners, contractors, and authorities having jurisdiction make informed maintenance and compliance decisions.

How Fire Sprinkler Testing Reduces Risk and Supports Compliance

Overtime, corrosion, obstructions, mechanical damage, environmental exposure, and degradation can impact sprinkler performance in ways that are not always apparent through visual inspection alone. Left unaddressed, these conditions can compromise system reliability and increase the risk of impaired fire protection. Fire sprinkler testing helps reduce this risk by identifying issues that could be detrimental to a sprinkler’s ability to function as intended prior to a fire event.

Laboratory testing provides objective data on sprinkler operating characteristics, including operating characteristics, including sensitivity and functionality. This information allows owners, contractors, facility managers, and fire protection professionals to make informed maintenance, replacement, and risk management decisions before performance issues lead to system failures. Testing also supports compliance with NFPA requirements that include the testing of representative sprinkler samples and the evaluation of sprinklers that may be affected by age, environmental conditions, corrosion, loading, or physical damage.

By proactively evaluating and documenting sprinkler performance, fire sprinkler testing helps support code compliance, maintain system reliability, and protect life safety.

Fire Sprinkler Certifications

Dyne is accredited for ISO/IEC 17025 - Mechanical Testing of Automatic Field Sprinklers.
Dyne is also ISO 9001 Certified.

Relevant Fire Sprinkler Standards and Test Methods

NFPA 25: Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems (*Testing fulfills NFPA 25 2023 Edition 5.3.1.1.)
Procedure based on UL 199, Edition 13 (Section 33.2 and NFPA 25 2023 Edition 5.3.1.1.)

What types of samples are tested?

Dyne Fire Protection Labs tests all types of fire sprinklers:

• Standard

• Fast Response

• Dry

When is Fire Sprinkler testing typically required?

See fire sprinkler testing intervals chart (link).

How are test results delivered?

Test results are delivered via email within 5 business days or less from the receipt of the sample(s). System tags for passing samples are mailed via USPS by request on the sample return form.

Do dry sprinklers need to be tested?

Yes dry sprinklers are also required to be tested. In fact, dry sprinklers have been shown to be more likely to fail sooner in the field and as a result, they must be either replaced or tested every 20 years (previous versions 15 years) and every 10 years after that.

How should I mark or label each sprinkler?

We provide sprinkler tags in our kits, but we also have a downloadable PDF (link) under Resources that you can use to make tags. We recommend that the sprinklers are labeled to match the sprinkler sample return form (ie #1 office, #2 garage, #3 warehouse, #4 lab).

Who should I contact to get started?

You can contact Dyne Fire Protection Labs to discuss your testing needs.
