- Corrosion damage/products and mineral deposits can restrict water flow and impair mechanical operation, leaving facilities vulnerable (+ PINHOLE LEAKS).
- Corrosion occurs in ALL fire protection sprinkler systems.
Why Test with Dyne:
- Test reports in 5-business days or less
- Free Corrosion & MIC sample kits
- Free shipping within the contiguous United States (limited free 1-way shipping to Alaska, Hawaii, Puerto Rico, and Canada, inquire for details)
- Rush 24 hour turn-around available
- Comprehensive reports
- Online access to results and return forms
- Immediate communication with our quality technicians and customer service staff
More Dyne Advantages:
- Preservation buffer is included in our sample kit to ensure your sample (microbial activity) doesn’t change in transit. This eliminates the need for shipping overnight on ice.
- Polymerase Chain Reaction (PCR) We are bringing PCR to the fire protection market.The go-to technology already in other markets (pharmaceutical, oil & gas, etc.), PCR is a technique used to quickly and accurately extract, amplify (thermal cycling) and then quantify (fluorescence) targeted DNA.As a result, MIC results can be obtained in hours instead of days/weeks, as is common with the incubation methods on the market today.
NFPA 25 Standard for Inspection, Testing and Maintenance of Water-Based Fire Protection Systems 2026 Edition
14.2.1.1 An assessment of the internal condition of piping shall be conducted at a minimum of every 5 years or in accordance with 14.2.1.2 for the purpose of inspecting for the presence of foreign organic and inorganic material.
14.2.1.3 Tubercules or slime, if found, shall be tested for indications of microbiologically influenced corrosion (MIC).
A representative sample is important as corrosion and MIC can vary throughout a system. Consider sampling in areas of concern based on the visual inspection or where pockets of air may be trapped.
NFPA 13 Standard for the Installation of Sprinkler Systems 2025 Edition
5.1.4.1 Water supplies and environmental conditions shall be evaluated for the existence of microbes and conditions that contribute to microbiologically influenced corrosion (MIC).
5.1.4.2 Water supplies and environmental conditions shall be evaluated for conditions that contribute to unusual corrosive properties.
A sample of the supply water for a system can provide information on the water corrosivity and microorganisms in the water that may be helpful for implementing corrosion mitigation techniques or water treatment needs.
The corrosion panel of tests will provide an evaluation of corrosion risk instead of pass/fail result. This information can be used when implementing the appropriate corrosion mitigation technique or to evaluate the effectiveness of a mitigation technique over time with ongoing testing.
A sample with more aggressive/higher risk results will indicate the system is more likely to have issues related to general corrosion and/or MIC.
