Field Sprinkler Testing Tool

The cost is determined by the number of sprinklers and the speed of service (regular or expedited). For accurate pricing, look at the Sprinkler Order Request form in the Field Sprinkler Testing tool. You can calculate the amount of an order in the Product Information section. Review the demo video for a preview of the calculation step.

For orders under $5,000, we accept all major credit cards including Visa, Mastercard, American Express and Discover. For orders $5,000 and over, payment must be completed by purchase order.

If paying with a credit card, your card will be processed once samples have been received and we have confirmed the number of submitted samples. For all other payment methods, an invoice will be submitted after testing has been completed.

Review the demo video for an overview of how to submit an order.

Navigate to the “Order Request – Submitted” tab. In this view, you will see order information like your company name, contact name, number of sprinklers, number of sample tags, lab status and project number. The lab status will update as the project progresses.

You can update occupant information in the tool if the sample testing has yet to be completed. To update occupant information, click on “Update Occupant,” search by order number and select “Edit.”

All prior submittals can be found under the “Historical Data” tab. Data migration is still in progress and is expected to be completed by the end of September 2025. If you require a copy of a report prior to that date, please send a request including the Lot and Occupant details to nbk.fieldsprinkler@ul.com.

In accordance with NFPA 25, a representative sample should consist of a minimum of four sprinklers or 1% of the number of sprinklers per individual sprinkler sample, whichever is greater. Additionally, similar sidewall, upright and pendent sprinklers produced by the same manufacturer within an environment could be considered part of the same sample, but additional sprinklers must be included if produced by a different manufacturer.

Customers must first submit an order in the Field Sprinkler Testing tool prior to sending in sample sprinklers. We are unable to conduct testing on samples without an open order.

• Wrap each sprinkler sample in soft packing firmly but not tightly around parts. Pack snugly for shipment, using adequate dunnage such as foam, air-cellular cushioning or other padding material to fill void spaces to prevent disturbance or damage during transit. Additional packaging may be necessary for transporting dry-type sprinklers. Any sprinkler received by UL Solutions that shows signs of mechanical damage will be recorded as such, regardless of whether the damage occurred during transit or field service.
• Properly replace the samples removed from the system with new sprinklers. UL Solutions testing is destructive, and the samples will not be returned.
• During the sprinkler removal process, attach the UL Solutions provided identification tags to the samples, identifying the on-line order number (SP number), location and room environment on the tag. Please write clearly and provide detailed information on the sprinkler tag.

In the Field Sprinkler Testing tool, navigate to the “Order Request – Submitted” tab. Find the order label you want to print, and select “Print Label.” You should print two copies — one for the outside of the box and one for the inside. This will help us process the receipt of the sprinklers.

If you need to request testing for multiple locations, please enter each location separately into the online ordering website. This will generate a unique order number (SP number) for each location, making it easier to trace any failed results back to the specific location.
