BACnet Testing Laboratories (BTL) provide industry members with verification testing services to ensure interoperability between BACnet devices. As manager of BTL, I see the benefits of verification through testing. I also see the hurdles of verification through testing. I am constantly learning from the experience, and I strive continuously to incorporate what the testing reveals into improving the process for both testers and testing applicants. Testing starts when BTL receives a testing application form that helps us gauge and estimate the amount of time, and which tests, will be performed on the device.
