UL, ULC and FM Testing Gallery

This is a gallery of pictures from the week of UL, ULC and FM testing at the CIT laboratory in Fresno. Almost all readers will find this gallery very boring, but we are certain that a few people will find this gallery very interesting.

Completed 100% of the product testing requirements for UL, ULC and FM for the entire Deringer backflow product line! In ONE WEEK!

How to properly represent the significance of this post was definitely a challenge. In a single week the Backflow Direct Team successfully completed 100% of the product testing requirements for UL, ULC and FM for the entire Deringer backflow product line. To our knowledge, no company in the backflow industry has ever accomplished such a feat. A recap of the week in a simple parody: Backflow Direct Team: ONE Standard Inspectors: TWO  Approval Agencies Represented: THREE (UL, ULC and FM) Product Models Tested: FOUR (DC/DCDA/RP/RPDA) Product Sizes Tested: FIVE (2 ½", 3", 4", 6" and 8") Days to Complete: SIX Dedicated Participants: SEVEN Weeks of Preparation: EIGHT Unique Products Tested: 35 Test Requirements Completed: 316 100% Successful: PRICELESS… …because of the evolving nature of the backflow approval process, it is also very likely that such a feat will never be duplicated. Without a doubt this is the most significant accomplishment in the young life of this company. Lou and Matt your loyalty and hard work are greatly appreciated! Hunter (my son)…your participation in this adventure made it all the more special!

We have spent the last few weeks designing and building the vertical flow systems necessary to complete the UL and FM testing scheduled for next week. The lab testing on these systems was successful, pretty cool and really LOUD!

We would like to thank Suzanne Tosterud from Underwriters Laboratory (UL) for her dedication and energy during the preparation and arduous testing of Deringer product line. Her efforts relative to pre-test planning, fusing of UL and ULC standards, calibration certificate acquisition, days of tedious data recording, knowledge of standards and commitment to an orderly testing process were invaluable in the successful completion of this massive project. Thank you Suzanne!!

We would like to thank Chris Tolentino from Factory Mutual (FM) for his positive attitude and engineering perspective throughout the planning and testing of the Deringer product line. Chris’s commitment to completely understanding the engineering behind the Deringer product line, was critical in the elimination any redundant testing required by FM standards. His efforts helped create a very efficient and thorough testing schedule resulting in the successful completion of this likely unprecedented project. Thank you Chris!!
